<u>Answer:</u> The half life of the decomposition reaction is 0.204 s

<u>Explanation:</u>

The equation used to calculate half life for first order kinetics:

t_{1/2}=\frac{0.693}{k}

where,

k = rate constant of the reaction = 3.40s^{-1}

t_{1/2} = half life of the reaction = ?

Putting values in above equation, we get:

t_{1/2}=\frac{0.693}{3.40s^{-1}}\\\\t_{1/2}=0.204s

Hence, the half life of the decomposition reaction is 0.204 s

Hey There:

First order  half life equation :

T 1/2  = ln ( 2 ) /K

T 1/2 = 0.693 / 3.40

T 1/2 = 0.204 s

Kinetic energy is energy of motion. What below is considered to be a form of kinetic energy?
gregori [183]

Answer:

In physics, the kinetic energy of an object is the energy that it possesses due to its motion It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity Having gained this energy during its acceleration the body maintains this kinetic energy unless its speed changes

Example:

A semi-truck travelling down the road

A river flowing at a certain speed

REY [17]

Answer:

See explaination

Explanation:

Chiral carbons are carbons that have four different groups, so C atoms 1, 4, and 5 are chiral carbons and thus H atoms are shown for those atoms.
