The isomerization of methylisonitrile to acetonitrile (CH3NC(g) ???? CH3CN) is first order in CH3NC. The rate constant for the r

Hoochie [10]

Answer:

The half life is $H_{1/2}= 7333.3sec$

Explanation:

The half life of a first order reaction is mathematically represented as

$H_{1/2} = \frac{0.693}{Rate Constant }$

Substituting $9.45 * 10^{-5}s^{-1}$ for the rate constant

$H_{1/2} = \frac{0.693}{9.45*10^{-5}}$

$H_{1/2}= 7333.3sec$

What is the relationship between a chemical equation and a chemical reaction? What are reactants and products in a chemical equa

Sergio039 [100]

Answer:

A chemical reaction occurs when reactants are converted into products. A chemical equation is a representation of a chemical reaction using chemical symbols. The chemical equation also indicates the physical state of the reactants and products. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.

When water vapor changes to a liquid what is it called

Mademuasel [1]

Answer:

$hello \: your \: answer \: is \: here.$

Explanation:

<h2>Condensation is the change of water from its gaseous form (water vapor) into liquid water. Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets.</h2>
