When 7.524 is rounded to 3 significant figures, it will be 7.52.

The process of changing a number to a nearby number with fewer significant digits is known as rounding.

Rounding can be done to the nearest integer, the nearest tenth, the nearest hundredth, and so on.

Here are some pointers on rounding numbers to a certain number of significant digits:If the digit following the last significant digit is less than 5, simply drop it and all following digits.

(round down)For example, 2.832 rounded to two significant digits is 2.8 since the 3 is followed by a 2 which is less than 5.

If the digit following the last significant digit is greater than 5, add 1 to the last significant digit, then drop all of the digits that follow it.

(round up)For example, 4.673 rounded to two significant digits is 4.7 since the 3 is followed by a 7 which is greater than 5.

If the digit following the last significant digit is exactly 5, the preceding digit is odd, and no other digits follow, increase the last significant digit by 1.

If the digit following the last significant digit is exactly 5, the preceding digit is even, and no other digits follow, simply leave the last significant digit alone.

For example, 2.875 rounded to two significant digits is 2.9 since the 5 is followed by an odd number, which means that the 8 should be rounded up, while 2.765 rounded to two significant digits is 2.8 since the 5 is followed by an even number, which means that the 6 should be left alone.

Answer:

The answer is C

Explanation:

It just makes the most sense to me

The mass percentage of C in morphine would be 4.21%.

The mass percentage of a composition in a compound is the mass of the composition relative to the mass of the entire compound. This can be mathematically expressed as:

Mass percentage = mass of component/mass of substance x 100%

In this case, we are looking for the mass percentage of C in \(C_{17}H_{19}NO_3\).

Molar weight of C = 12 g/mol

Molar mass of  \(C_{17}H_{19}NO_3\) = (12x17) + (1x19) + (14x1) + (16x3)

                                             = 285 g/mol

Mass percentage of C = 12/285

                                     = 4.21% to 2 decimal places.

In other words, the mass percentage of C in morphine is 4.21%.

To name Type 2 ionic compounds such as AuCl₃, you need to use the Stock system or Roman numeral system to indicate the oxidation state of the cation. Some steps are; Identify the cation, Determine the charge, Write the name, and combine two names.

Here are the steps to name AuCl₃; Identify the cation and anion. In this case, the cation is Au³⁺ and the anion is Cl⁻.

Determine the charge on the cation by using the anion's charge and balancing the charges to zero. Since Cl⁻ has a charge of -1 and there are three Cl⁻ ions in the compound, the total negative charge is -3. Therefore, the Au³⁺ ion has a charge of +3.

Write the name of the cation first, followed by the name of the anion with an -ide ending. Since the cation is Au³⁺, we use the name "gold(III)" to indicate the oxidation state of +3. The anion is Cl⁻, so we add the -ide ending to get "chloride".

Combine the two names to get the compound's name: "gold(III) chloride".

Therefore, the name of the Type 2 ionic compound AuCl₃ is "gold(III) chloride".

Considering the definition of isotopes and atomic mass of an element, the percentages of Z-29 and Z-30 in nature are 4.66% and 3.11% respectively.

The same chemical element can be made up of different atoms with different numbers of neutrons. These atoms are called isotopes of the element.

The atomic mass of an element is the weighted average mass of its natural isotopes, considering the relative abundance of each of them.

In this case, you know:

Being the total percent natural abundance equal to 92.23% + x% + y%= 100%, then:

y%= 100% - 92.23% - x%

y%= 7.77% - x% or y=0.0777 - x

Then, the average mass of Z can be calculated as:

27.977 amu×0.9223 + 28.976 amu× x +29.974 amu× y= 28.0855 amu

Replacing the expression of y:

27.977 amu×0.9223 + 28.976 amu× x +29.974 amu× (0.0777 - x)= 28.0855 amu

Solving:

27.977 amu×0.9223 + 28.976 amu× x +29.974 amu× 0.0777 - 29.974 amu× x= 28.0855 amu

28.132 amu - 0.998 amu× x= 28.0855 amu

- 0.998 amu× x= 28.0855 amu - 28.132 amu

- 0.998 amu× x= -0.0465 amu

x= (-0.0465 amu)÷ (-0.998 amu)

x= 0.0466= 4.66%

Remembering that y%= 7.77% - x%, you get:

y%= 7.77% - 4.66%

y%= 3.11%

Finally, the percentage of Z-29 is 4.66% and the percentage of Z-30 is 3.11%.

It's a chemical change.

Explanation:-

Formation of crystals of sugar from a sugary syrup is a chemical change. Because, we cannot get sugary syrup back from the sugar crystals. Yet, it is chemical change.

Answer:

First, let's calculate the number of moles of H₂SO₄:

Number of moles of H₂SO₄ = mass of H₂SO₄ / molar mass of H₂SO₄

Number of moles of H₂SO₄ = 583 g / 98.079 g/mol

Number of moles of H₂SO₄ = 5.944 mol

Next, let's calculate the number of moles of water:

Number of moles of water = mass of water / molar mass of water

Number of moles of water = 1.50 kg / 18.0153 g/mol

Number of moles of water = 83.277 mol

The mole fraction of H₂SO₄ can now be calculated as follows:

Mole fraction of H₂SO₄ = moles of H₂SO₄ / total moles

Mole fraction of H₂SO₄ = 5.944 mol / (5.944 mol + 83.277 mol)

Mole fraction of H₂SO₄ = 0.0666

Therefore, the mole fraction of H₂SO₄ in the solution is 0.0666 (rounded to four significant figures).

Answer:

C₅H₁₀.

Explanation:

To determine the molecular formula of the compound, we need to know the molar mass of the compound. Since the empirical formula is CH₂, the empirical molar mass can be calculated as:

Empirical molar mass = 12.01 g/mol (atomic mass of C) + 2(1.01 g/mol) (atomic mass of H)

Empirical molar mass = 14.03 g/mol

The molecular mass of the compound is given as 70.15 g/mol. To find the molecular formula, we need to know how many empirical units are present in the molecule. This can be calculated by dividing the molecular mass by the empirical molar mass:

Number of empirical units = Molecular mass / Empirical molar mass

Number of empirical units = 70.15 g/mol / 14.03 g/mol

Number of empirical units = 5

This means that there are 5 empirical units (CH₂) present in the molecular formula of the compound. Therefore, the molecular formula is:

Molecular formula = 5(CH₂) = C₅H₁₀

Thus, the molecular formula of the compound is C₅H₁₀.

Hello!

In this case, since addition reactions imply that a radical or some radicals are added to the parent chain, we notice that only unsaturated hydrocarbons are able to undergo addition whereas saturated ones undergo substitution reactions as they already have all the carbon bonds bonded to leaving groups.

In such a way, we can rule out C2H6, C3H8 and CH4 as they are all alkanes; therefore, only С3Н6 is able to undergo an addition reaction due to the C=C which is able to lose one of those bonds and allow an incoming radical to get included into the parent chain.

An increased temperature generally causes a reaction to occur faster rather than slower. Therefore option C is correct.

The increased temperature leads to a higher average kinetic energy of the molecules, which results in more frequent and energetic collisions between the reactant particles.

This increased collision frequency and energy facilitate the breaking of chemical bonds and the formation of new bonds, leading to an accelerated reaction rate.

When the temperature is raised, the kinetic energy of the molecules increases. This means that the individual molecules move faster and possess a greater amount of energy. As a result, the molecules collide more frequently and with higher energy, enhancing the likelihood of successful collisions that lead to a reaction.

In summary, an increased temperature leads to a faster reaction rate by increasing the average kinetic energy of the particles, causing more frequent and energetic collisions.

Global warming is a phenomenon that has become an increasing concern worldwide.

The increase in Earth's average surface temperature due to rising levels of greenhouse gases, particularly carbon dioxide, in the atmosphere is referred to as global warming.

It is most closely associated with climate change.

It is a long-term trend that has become one of the most pressing environmental problems facing our planet today.

The primary cause of global warming is human activity.

Human beings are responsible for releasing large amounts of carbon dioxide, methane, and other greenhouse gases into the atmosphere through the burning of fossil fuels such as coal, oil, and natural gas.

These gases trap heat from the sun's rays and cause the Earth's temperature to rise, leading to global warming.

The effects of global warming can be seen in rising sea levels, more frequent and severe weather events such as hurricanes, droughts, and floods, and the melting of ice caps and glaciers.

It is also having a significant impact on the world's ecosystems, with changes in temperature and precipitation patterns affecting the distribution and abundance of plant and animal species.

Although global warming is a serious issue, there are ways to reduce its impact.

Reducing our dependence on fossil fuels by transitioning to renewable energy sources such as wind and solar power can help to reduce greenhouse gas emissions.

Additionally, planting trees and other vegetation can help to absorb carbon dioxide from the atmosphere and store it in the ground. Education and awareness-raising can also help individuals and communities take action to mitigate the effects of global warming.

When dissolved in water, most Group 1 metal salts can be described as strong electrolytes.

When Group 1 metal salts are dissolved in water, they can be described as strong electrolytes. This is because Group 1 metals, such as lithium (Li), sodium (Na), potassium (K), and so on, readily lose their outermost valence electron to form positive ions (cations). These cations then dissociate completely in water, separating from the anions to which they were originally bonded.

The dissociation of Group 1 metal salts in water results in the formation of positively charged metal ions and negatively charged non-metal ions (anions). These ions are free to move and conduct electric current, making the solution a good conductor of electricity. The complete dissociation of Group 1 metal salts in water and the presence of freely moving ions make them strong electrolytes.

Strong electrolytes are substances that ionize completely or almost completely in solution, producing a high concentration of ions. This is in contrast to weak electrolytes, which only partially ionize and produce a lower concentration of ions.

In summary, when Group 1 metal salts are dissolved in water, they form strong electrolytes due to their ability to dissociate completely into ions, leading to a high concentration of freely moving ions in the solution, thus enabling efficient electrical conductivity.
