ability to react with other elements
Explanation:
As size increases<span> or decreases, </span>DENSITY REMAINS THE SAME<span>! As a rule, things that are MORE dense will sink or fall to the bottom of things that are LESS dense (think of oil and water). ... Notice that </span>if<span> you DECREASE the </span>mass<span> of something or</span>INCREASE<span> the </span>volume<span>, the </span>density<span> will be less…</span>

Explanation:
Answer:
k = 4.85 x 10⁻³ / s
Explanation:
For a first order reaction we have two very important equations we need to memorize:
ln ( N/N₀ ) = -kt
and,
0.693/ k = t₁/₂
where k is the rate constant and t i is the halflife which can be derived from the first equation.
0.693/ k = t₁/₂ ⇒ k = 0.693 / t₁/₂
k = 0.693 / 143 s = 4.85 x 10⁻³ / s
