NH4OH --> Predict the products

Chemistry
1 answer:
Sav [38]3 years ago
4 0

Answer: NH3 and H2O

Explanation:

NH4OH(l) --> NH3(g) + H2O(g)

Ammonia liquor, NH4OH is an highly unstable hydroxide of ammonium, hence it decomposes on heating to produce ammonia gas, NH3 which is liberated to the surroundings and water, H2O evaporated as steam. In a reverse reaction, ammoniacal liquor is formed by dissolving gaseous ammonia in cold water.

Thus, the products of NH4OH break down are NH3 and H2O

A system gains 687 kJ of heat, resulting in a change in internal energy of the system equal to 156 kJ. How much work is done?
Maslowich

Answer:

w = -531 kJ

1. Work was done by the system.

Explanation:

Step 1: Given data

  • Heat gained by the system (q): 687 kJ (By convention, when the system absorbs heat, q > 0).
  • Change in the internal energy of the system (ΔU°): 156 kJ

Step 2: Calculate the work done (w)

We will use the following expression.

ΔU° = q + w

w = ΔU° - q

w = 156 kJ - 687 kJ

w = -531 kJ

By convention, when w < 0, work is done by the system on the surroundings.

Classify the following alcohol as primary,
Nata [24]

The classification of the alcohols gives;

  • Compound 1 - Primary alcohol
  • Compound 2 - Tertiary alcohol
  • Compound 3 - Secondary alcohol
  • Compound 4 - Secondary alcohol

<h3>What are alcohols?</h3>

Organic compounds occurs in families. The family of compounds is called a homologous series. The homologous series always have a functional group. The functional group is the atom, group of atoms or bond that is responsible for the chemical reactivity of the members of a given homologous series.

Now we know that the alcohols are those organic compounds that contains the -OH group. The could be aliphatic or alicyclic compounds. We shall now proceed to name the kind of alcohols that each of the compounds shown are;

  • Compound 1 - Primary alcohol
  • Compound 2 - Tertiary alcohol
  • Compound 3 - Secondary alcohol
  • Compound 4 - Secondary alcohol

Which of the following processes have a ΔS &lt; 0? Which of the following processes have a ΔS &lt; 0? carbon dioxide(g) → carbon
Umnica [9.8K]

Answer:

All of the above processes have a ΔS < 0.

Explanation:

ΔS represents change in entropy of a system. Entropy refers to the degree of disorderliness of a system.

The question requests us to identify the process that has a negative change of entropy.

carbon dioxide(g) → carbon dioxide(s)

There is  a change in state from gas to solid. Solid particles are more ordered than gas particles so this is a negative change in entropy.

water freezes

There is  a change in state from liquid to solid. Solid particles are more ordered than liquid particles so this is a negative change in entropy.

propanol (g, at 555 K) → propanol (g, at 400 K)

Temperature is directly proportional to entropy, this means higher temperature leads t higher entropy.

This reaction highlights a drop in temperature which means a negative change in entropy.

methyl alcohol condenses

Condensation is the change in state from gas to liquid. Liquid particles are more ordered than gas particles so this is a negative change in entropy.
