Carbon dioxide molecules can absorb and emit infrared radiation, and they are one of the most abundant constituents of Earth's atmosphere.

Thus, the correct options are:d) Are one of the most abundant constituents of Earth's atmospheree) Can move in many ways, thus absorbing and emitting infrared radiation

Carbon dioxide is a trace gas present in the Earth's atmosphere. It's a vital component of Earth's carbon cycle, which helps to regulate Earth's temperature and support life as we know it. Carbon dioxide molecules are one of the most common gases in the atmosphere, accounting for around 0.04% of the Earth's atmosphere.

The greenhouse effect is caused by carbon dioxide, methane, and other greenhouse gases. When the Sun's energy reaches the Earth's surface, it is absorbed and then radiated back into space as infrared radiation. Greenhouse gases absorb this radiation and trap it in the atmosphere, which causes the Earth's temperature to rise and the climate to change.

Carbon dioxide molecules are capable of absorbing and emitting infrared radiation due to their molecular structure, which consists of one carbon atom and two oxygen atoms. This property of carbon dioxide is the main reason it's classified as a greenhouse gas.

Explanation:

The final temperature can be calculated using the calorimetric equation. Here, the final temperature of water is 27.71 °C.

The calorimetric equation connecting the heat energy absorbed or released q by a system with the mass m, temperature difference ΔT and the specific heat capacity c as follows:

q = m c ΔT

The specific heat capacity of water = 4.15 J/ °C g.

given that heat energy absorbed q = 9000 J

mass = 800 g

initial temperature = 25 °C.

Then,

9000 J = 4.15 J/ °C g. × 800 g (25 °C + T)

then T = [ 9000 J/  4.15 J/ °C g. × 800 g ] + 25 °C = 27.71  °C.

Therefore, the final temperature of water is 27.71  °C.

On the periodic table, the ionization energy often decreases as one moves down a group (column). This is due to the fact that there are more energy levels (shells) and valence electrons are located further away from the positively charged nucleus as you progress down a group. As a result, they are not held as firmly and are easier to remove.

Additionally, as the number of energy levels rises, the shielding effect of inner electrons grows, further lowering the effective nuclear charge experienced by the valence electrons and making them simpler to remove.

For instance, due to the stability of the half-filled p-orbitals in Group 13, the first ionization energy of Group 3A (or Group 13) elements, such as boron and aluminium, is higher than that of Group 2A (or Group 2) elements, such as beryllium and magnesium.

Similar to this, the first ionisation energy of Group 6A (or Group 16) elements, such as oxygen and Sulphur, is higher than that of Group 5A (or Group 15) elements, such as nitrogen and phosphorus, because the smaller and more highly charged oxygen and Sulphur atoms exhibit more electron-electron repulsion.

In conclusion, there can be exceptions due to various causes, but the overall trend of ionisation energy when advancing down a group of the periodic table is a decrease due to growing distance between valence electrons and the nucleus and the shielding effect of inner electrons.

Answer:

1425 mmHg.

Explanation:

The following data were obtained from the question:

Initial volume (V1) = 1.5 L

Initial pressure (P1) = 1 atm

Final volume (V2) = 0.8 L

Final pressure (P2) =?

Next, we shall determine the final pressure of the gas by using the Boyle's law equation as follow:

P1V1 = P2V2

1 × 1.5 = P2 × 0.8

1.5 = P2 × 0.8

Divide both side by 0.8

P2 = 1.5/0.8

P2 = 1.875 atm

Finally, we shall convert 1.875 atm to mmHg.

This can be obtained as follow:

1 atm = 760 mmHg

Therefore,

1.875 atm = 1.875 × 760 = 1425 mmHg.

Therefore, the new pressure of the gas is 1425 mmHg.

Determine the volume of the sample of CO2(g) if the temperature and pressure are changed to 336K and 152.0 kPa. Answer-->151 mL (PV/T=PV/T ) 60.

The combined gas law gives the value of the volume. The final volume at 336 K is 151.3 mL.

Charle's, Boyle's, and Gay-Lussac's laws together give the combined gas law. It is given as:

PV / T = k

Given,

Initial volume = 200 mL

Initial pressure = 101.3 kPa

Initial temperature = 296 K

Final pressure = 152 kPa

Final temperature = 336 K

The final volume is calculated as:

(P₁V₁) ÷ T₁ = (P₂V₂) ÷T₂

(101.3 × 200) ÷ 296 = (336 × V) ÷ 152

V = 151.3 mL

1344.6 grams of K are needed to obtain 27.6 grams of H2 with an 80.2% yield.

To determine the mass of K needed, we first need to balance the chemical equation:

2K + 2HCl → 2KCl + H2

Next, use the molar mass of H2 (2 g/mol) to find moles of H2:

27.6 g H2 * (1 mol H2 / 2 g H2) = 13.8 mol H2

Since the ratio of K to H2 is 2:1, we need twice the moles of K:

13.8 mol H2 * (2 mol K / 1 mol H2) = 27.6 mol K

Now, we must account for the 80.2% yield:

27.6 mol K / 0.802 = 34.4 mol K

Finally, use the molar mass of K (39.1 g/mol) to find the mass of K:

34.4 mol K * (39.1 g K / 1 mol K) = 1344.6 g K

So, 1344.6 grams of K are needed to obtain 27.6 grams of H2 with an 80.2% yield.

The molarity of the solution is 1.4 M, calculated by dividing the number of moles of solute (0.35) by the volume of the solution in liters (0.25).

Molarity (M) is a unit of concentration that expresses the number of moles of solute dissolved in one liter of solution. To calculate the molarity of a solution, you need to know the number of moles of solute and the volume of the solution in liters.

In this case, the solution contains 0.35 moles of solute and has a volume of 250 ml. To convert the volume to liters, you need to divide it by 1000 ml/L, which gives:

250 ml / 1000 ml/L = 0.25 L

Now, you can use the formula for molarity:

M = moles of solute/liters of solution

Substituting the values, you get:

M = 0.35 moles / 0.25 L = 1.4 M

Therefore, the molarity of the solution is 1.4 M.

Electron affinity is a measure of an atom's ability to attract and gain an electron. It quantifies the energy change that occurs when an atom in the gaseous state acquires an electron, indicating how readily an atom can accept an additional electron.

Electron affinity is defined as the energy change when an isolated gaseous atom gains an electron to form a negatively charged ion. It is expressed in units of energy (usually kilojoules per mole) and can be either positive or negative. A positive electron affinity indicates that energy is released when an atom gains an electron, while a negative electron affinity indicates that energy must be supplied for the atom to accept an electron.

The magnitude of an atom's electron affinity depends on various factors, including its atomic structure and the electron configuration in its valence shell. Generally, atoms with a higher effective nuclear charge and a smaller atomic radius tend to have a higher electron affinity. Elements on the right side of the periodic table, such as halogens, typically have high electron affinities since they strongly desire to attain a stable electron configuration by gaining one electron. In contrast, noble gases have low electron affinities since their electron configurations are already highly stable.

Explanation:

Based on Charles's law, the volume of a gas is directly proportional to absolute temperature. The formrula is:

V₁ / T₁ = V₂ / T₂

Where 1 represents the initial state and 2 the final state of the gas

Using the values of the problem:

V₁ = 10.0L

T₁ = 127°C + 273.15K = 400.15K

V₂ = 20.0L

Thus, replacing in the formula:

10.0L / 400.15K = 20.0L / T₂

T₂ = 800K

In Celsius:

800K - 273.15 = 526.85K

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 5.33 L

Initial temperature (T₁) = 21 °C

Final temperature (T₂) = 10 °C

Final volume (V₂) =?

Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

Initial temperature (T₁) = 21 °C

Initial temperature (T₁) = 21 °C + 273

Initial temperature (T₁) = 294 K

Final temperature (T₂) = 10 °C

Final temperature (T₂) = 10 °C + 273

Final temperature (T₂) = 283 K

Finally, we shall determine the final volume. This can be obtained as follow:

Initial volume (V₁) = 5.33 L

Initial temperature (T₁) = 294 K

Final temperature (T₂) = 283 K

Final volume (V₂) =?

V₁/T₁ = V₂/T₂

5.33 / 294 = V₂ / 283

Cross multiply

294 × V₂ = 5.33 × 283

294 × V₂ = 1508.39

Divide both side by 294

V₂ = 1508.39 / 294

V₂ = 5.13 L

To calculate the theoretical yield of potassium alum, we need to determine the number of moles of aluminum present in the 1.16 g sample and then use the stoichiometry of the reaction to find the corresponding number of moles of potassium alum.

Therefore, the theoretical yield of potassium alum that could be obtained in the reaction is approximately 10.23 grams.

First, we calculate the number of moles of aluminum using its molar mass:

Number of moles of aluminum = Mass of aluminum / Molar mass of aluminum

= 1.16 g / 26.98 g/mol (molar mass of aluminum)

≈ 0.043 moles

Next, we use the balanced chemical equation for the reaction between aluminum and potassium alum to find the mole ratio between aluminum and potassium alum. The balanced equation is:

2 Al + K2SO4 · Al2(SO4)3 + K2SO4

From the balanced equation, we see that 2 moles of aluminum react to form 1 mole of potassium alum.

Therefore, the theoretical yield of potassium alum is:

Theoretical yield = Number of moles of aluminum * (1 mole of potassium alum / 2 moles of aluminum)

= 0.043 moles * (1 mole / 2 moles)

= 0.0215 moles

Finally, we convert the number of moles of potassium alum to grams using its molar mass:

Theoretical yield in grams = Theoretical yield in moles * Molar mass of potassium alum

= 0.0215 moles * 474.39 g/mol (molar mass of potassium alum)

≈ 10.23 g

Therefore, the theoretical yield of potassium alum that could be obtained in the reaction is approximately 10.23 grams.
