N2 H2 ——> NH3

Add a 3 in front of H2 and a 2 in front of NH3

So the answer would be

N2 3H2 ——> 2NH3

Use your understanding of the ideal gas law to identify the correct relationships among the variables. Pressure is . Temperature

MAXImum [283]

Answer:

Pressure is inversely proportional to the volume of a gas at constant temperature and number of moles

Temperature is directly proportional to volume at constant pressure and number of moles

Volume is directly proportional to the number of moles of a gas at constant temperature and pressure

Explanation:

The ideal gas law is derived from a combination of the Boyle's, Charles' and Avogadro's law of gases.

Boyle's law states that at constant temperature, the volume of a given mass of gas (number of moles of gas is constant) is inversely proportional to the pressure exerted by the gas.

V ∝ 1/P (at constant n, T)

Charles'law states that at constant pressure, the volume of a given mass of gas (constant amount, n) is directly proportional to the temperature of the gas; V ∝ T (at constant n, P)

Avogadro’s law states that at constant temperature and pressure, the volume of a given mass of gas is directly proportional to the number of moles of gas present; V ∝ n(at constant T, P)

Combining the three equations gives the following relationship: V ∝ nT/P

By inserting a proportionality constant called the molar gas constant, R, in the relationship above, the ideal gas equation is derived as follows:

V = nRT/P or PV = nRT

Would you expect the carbonyl carbon of benzaldehyde to be more or less electrophilic than that of acetaldehyde? Explain using r

Slav-nsk [51]

Answer:

Benzaldehyde is less electrophilic than acetaldehyde

Explanation:

Electrophilicity of carbonyl carbon depends on it's positive charge density.

In benzaldehyde, phenyl group can act as an electron donating group towards carbonyl group due to it's electron donating resonating effect.

In acetaldehyde, methyl group can act as an electron donating group towards carbonyl group due to it's electron donating inductive effect.

We know that resonating effect are more stronger than inductive effect.

Henece, it is expected that positive charge density on carbonyl carbon is much lower in benzaldehyde than acetaldehyde.

So, benzaldehyde is less electrophilic than acetaldehyde.

Resonating effect of phenyl group has been shown below.
