Suggest an experimental method for measuring the change in concentration with time for each of the following reactions:(b) 2NO(g
USPshnik [31]

The experimental method for measuring the change in concentration with time for the given reaction is by measuring the amount of gas a reaction releases over time.

2NO(g) + Cl₂(g) → 2NOCl(g)

<h3>What is reaction rate?</h3>
  • The reaction rate is the rate at which a chemical reaction proceeds.
  • Which is proportional to both the increase in a product's concentration per unit time and the decrease in a reactant's concentration per unit time.
  • There is a wide range in reaction times.
  • The general definition is that the term "rate of a reaction" refers to the pace at which a reaction occurs.
  • As an illustration, iron rusting has a low reaction rate since the process is slow but wood burning has a high reaction rate because the process is quick.

Calculate the energy required to move from solid water at 0 degrees C to liquid water at 0 degrees C
Serhud [2]

Answer:

Q = 334\,kJ

Explanation:

Let assume that 1 kilogram of water in solid state at one atmosphere of pressure. The fussion latent heat of 334\,\frac{kJ}{kg}, the heat required to change the phase of water is:

Q = m \cdot L_{f}

Q = (1\,kg)\cdot \left(334\,\frac{kJ}{kg} \right)

Q = 334\,kJ

What is the total number of nitrogen atoms in two mol of NH4NO3 ?
Fynjy0 [20]

Answer:

2.409 x 10²⁴

Explanation:

There are two nitrogens for every mole of NH₄NO₃

Since there are two moles, that means there are 4 nitrogens

There are 6.022 x 10²³ atoms in every mole of any element

(6.022 x 10²³) x 4 = 2.4088 x 10²⁴

Use sig figs to round it to 2.409 x 10²⁴
