Explanation:

Warm wind is present at the equator and because the molecules of warm air has more kinetic energy, therefore, they move away from the equator towards the poles.

Now, at the poles cold or cooler air is present which is replaced by warm air. Then this cooler air moves towards the equator.

Flow of these winds is due to the heat which helps in their movement.

Answer:

ΔG° = -5.4 kJ/mol

ΔG = 873.2 J/mol = 0.873 kJ /mol

Explanation:

Step 1: Data given

ΔG (NO2) = 51.84 kJ/mol

ΔG (N2O4) = 98.28 kJ/mol

Step 2:

ΔG = ΔG° + RT ln Q

⇒with Q = the reaction quatient

⇒with T = the temperature = 298 K

⇒with R = 8.314 J / mol*K

⇒with ΔG° = ΔG° (N2O4) - 2*ΔG°(NO2 )

⇒ ΔG° = 98.28 kJ/mol - 2* 51.84 kJ/mol

⇒ ΔG° = -5.4 kJ/mol

Part B

ΔG = ΔG° =RT ln Q

⇒with G° = -5.4 kj/mol = -5400 j/mol

⇒ with R = 8.314 J/K*mol

⇒with T = 298 K

⇒with Q = p(N2O4)/ [ p(NO2) ]² = 1.63/0.36² = 12.577

ΔG = -5400 + 8.314 * 298 * ln(12.577)

ΔG = -5400 + 8.314 * 298 * 2.532

ΔG = 873.2 J/mol = 0.873 kJ/mol

Wine goes bad soon after opening because the ethanol (CH,CH,OH) in it reacts with oxygen gas (0.) from the air to form water (11

daser333 [38]

<u>Answer:</u> The mass of water produced is 1.8 grams

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$ .....(1)

Given mass of ethanol = 4.59 g

Molar mass of ethanol = 46.07 g/mol

Putting values in equation 1, we get:

$\text{Moles of ethanol}=\frac{4.59g}{46.07g/mol}=0.0996mol$

The chemical equation for the reaction of ethanol with oxygen gas follows:

$CH_3CH_2OH+O_2\rightarrow CH_3COOH+H_2O$

By Stoichiometry of the reaction;

1 mole of ethanol produces 1 mole of water.

So, 0.0996 moles of ethanol will produce = $\frac{1}{1}\times 0.0996=0.0996mol$ of water.

Now, calculating the mass of water from equation 1, we get:

Molar mass of water = 18 g/mol

Moles of water = 0.0996 moles

Putting values in equation 1, we get:

$0.0996mol=\frac{\text{Mass of water}}{18g/mol}\\\\\text{Mass of water}=(0.0996mol\times 18g/mol)=1.8g$

Hence, the mass of water produced is 1.8 grams

Which taxonomic classification level is the largest or most broad?(1 point)

patriot [66]

According to the research, domain is the taxonomic classification level that is the largest or most broad.

<h3>What is domain?</h3>

It is the broadest taxonomic category in which known living things are classified.

In other words, it is the broadest category in which the different kingdoms of life can be organized, according to the classification models that are most widely accepted in the scientific community.

Therefore, we can conclude that according to the research, domain is the taxonomic classification level that is the largest or most broad.
