The percent by weight (w/w%) of sugar in soda : 6.216%

Given

mass of sugar = 23 g

total mass = 370 g

Required

the percent weight

Solution

%weight = (mass of solute : mass of solution) x 100%

solute = sugar

solution = solvent + solute = water + sugar

percent weight of sugar in soda :

= (23 : 370) x 100%

= 6.216 %

0.361 moles of N₂ were required to produce 12.3 g of NH₃, using the balanced chemical equation N₂ + 3H₂ → 2NH₃.

The balanced chemical equation for the reaction is N₂ + 3H₂ → 2NH₃. We can use the balanced equation and the molar mass of NH₃ to calculate the number of moles of N₂ required to produce 12.3 g of NH₃,

1 mol NH₃ = 2 mol N₂ (from the balanced equation)

molar mass of NH₃ = 17.03 g/mol

moles of NH₃ = 12.3 g / 17.03 g/mol

moles of NH₃ = 0.722 mol

moles of N₂ = (0.722 mol NH₃) / 2

moles of N₂ = 0.361 mol

Therefore, 0.361 moles of N₂ were needed to produce 12.3 grams of NH₃.

PLATO ANSWER

Answer:

\(m_{nitrogen}=14g\)

Explanation:

Hello,

In this case, since we are talking about a chemical reaction in which a compound having nitrogen and chlorine is decomposed into chlorine and nitrogen, we must remember that the law of conservation of mass must be obeyed, for that reason, we notice that the mass of the whole reactants must equal the mass of the whole products, as shown below:

\(m_{reactants}=m_{products}\)

Next, we know there is only one single reactant and products are constituted by both chlorine and nitrogen:

\(m_{reactant}=m_{chlorine}+m_{nitrogen}\)

In such a way, we can compute the mass of nitrogen as shown below:

\(m_{nitrogen}=m_{reactant}-m_{chlorine}=120.4g-106.4g\\\\m_{nitrogen}=14g\)

The term that refers to the passing of a wave through an object is "transmission."

Transmission refers to the process by which a wave passes through an object or medium. In the context of sound, transmission occurs when sound waves travel through different substances, such as air, water, or solids.

When a sound wave encounters an object, it can be transmitted through it, reflected off it, or absorbed by it, depending on the properties of the object and the medium through which the sound is traveling.

For example, when you speak into a microphone, the sound waves produced by your voice travel through the air and are transmitted to the microphone's diaphragm. The diaphragm converts the sound waves into electrical signals, which can then be amplified and reproduced as sound through speakers.

In summary, transmission is the term used to describe the passage of a wave, such as a sound wave, through an object or medium. It is an essential concept in understanding how waves interact with their surroundings and how sound propagates through different materials.

The given chemical equation, 2N₂ + 3H₂ <==>2NH3, is an example of a reversible reaction.option A.

The double arrows between the reactants and products indicate that the reaction can proceed in both directions, forming both products and reactants.The reversible reaction, also known as a chemical equilibrium reaction, refers to a chemical reaction that can occur in both forward and reverse directions. It occurs when reactants are converted into products, and the products are also converted back into the original reactants.A reversible reaction can be identified by the symbol “<==>” or “⇌” that appears between the reactants and products in the chemical equation. It denotes that the reaction is in a state of chemical equilibrium. When the reactants and products have achieved equilibrium, the rate of the forward and reverse reactions is equal, and there is no further net change in the amounts of the reactants and products.A combustion reaction is a type of exothermic reaction in which a substance reacts with an oxidizing agent to produce heat and light. A one-way reaction is a type of reaction that occurs in only one direction and cannot be reversed without significant changes to the reaction conditions, such as changing the temperature or pressure.A reversible reaction, unlike a one-way reaction, can occur in both directions and reach equilibrium when the forward and reverse reaction rates are equal.option A.

Answer:

when placed in water, a sodium pellet catches on fire as hydrogen gas is liberated and sodium hydroxide forms. chemical change = fire is a sign of chemical reaction.

Explanation:

When placed in water the sodium pellets catch the fire and liberate the hydrogen gas. On mixing with water solid sodium forms a colorless basic solution.

Sodium is a soft metal. It is a very reactive element with a low melting point. Sodium reacts very quickly with water, snow, and ice to produce sodium hydroxide and hydrogen. It is an alkali metal and the sixth most abundant metal on earth. It has a silvery white color.

It has a strong metallic luster. On reacting with oxygen it produces sodium oxide which on reacting with the water produces sodium hydroxide.

It is used to improve the structure of certain alloys and soaps. It is also used in the purification of metals. Sodium is also present in sodium chloride, an important compound found in the environment.

The best explanation for the increase in the number of plants with long, narrow flowers over time is option D: Individuals with long, narrow flowers produce more seeds than individuals with short, wide flowers.

In this population, short, wide flowers are better suited for bee pollination, while long, narrow flowers are more suitable for hummingbird pollination. Over time, the plants with long, narrow flowers produce more seeds compared to those with short, wide flowers.

This happens because the hummingbirds, which are the main pollinators for long, narrow flowers, are more effective in transferring pollen between these flowers. As a result, the long, narrow flower individuals have a higher reproductive success and pass on their traits to the next generation

The savanna grassy plain environment would best support large land animals like giraffes elephants and lions.

A dry climate with a distinct wet and dry season, as well as moderate to high temperatures is observed in savannas. Grass species which can withstand seasonal droughts and frequent fires, predominate in savanna vegetation. Although they are more widely spaced than in other forested environments, trees and shrubs are still present.

Large land animals thrive in the savanna because it offers a variety of food sources, such as grasses, leaves and fruits, as well as plenty of room to move around and find resources. Animals can see each other clearly and communicate effectively in the open grasslands and the scatted trees and shrubs provide shelter from the sun and wind.

Answer:

THE FRACTION OF IODINE-125 REMAINING AFTER 360 DAYS IS 1/64.

Explanation:

half life of iodine- 125 = 60 days

Time elapsed for a decay = 360 days

using the formula:

                            Nt = No (1/2)^t/t1/2

The fraction left after a decay will be represented as:

Nt / No = (1/2) ^t/t1/2

Nt / No = (1/2) ^ 360 /60

Nt / No = (1/2) ^6

Nt / No = 1 / 64

The fraction of iodine-125 (Nt / No) remaining after 360 days is 1/ 64.
