Answer:
1.6 × 10³ s
Explanation:
Let's consider the following generic reaction.
A → B
The rate law is:
![rate=k \times [A]^{m}](https://tex.z-dn.net/?f=rate%3Dk%20%5Ctimes%20%5BA%5D%5E%7Bm%7D)
where,
rate is the reaction rate
k is the rate constant
[A] is the molar concentration of the reactant A
m is the reaction order
When m = 1, we have a first-order reaction. We can calculate the half-life for this reaction using the following expression.
A: because lets say u have baking soda and vinegar when you mix the they make a gas that can fill a balloon meaning the gas increased so that would mean a solid would decreased
It represents a chemical change
<span>I would figure this out slowly. So the percentage would be 25 2.6 billion years ago. That would leave it at 50 percent 5.2 billion years ago. If you double that 50 percent to get 100% and double the 5.2 billion years you get 10.4 billion years. This would make the answer, the rock is 10.4 billion years old</span>
Hiii,so the problem is ♀️
