Half-life means that the matter degrades by 50% at each interval. 48.2 days is 2 intervals.
So, it would go down by 50% in the first interval, making it 50g. Then it would go down by another 50% from there, making the final amount of undecayed thorium-234 25g.
Answer:
<em>Rate</em> = k * [C₄H₆]²
Explanation:
It is possible to write the reaction as:
The differential rate law for a simple second order reaction of the type 2A → B is:
With the above information in mind, the rate law for the reaction of butadiene would be:
- <em>Rate</em> = k * [C₄H₆]²
Answer:
1) some of the gas maybe metal but non metal directly refers it self to not begin metal
2) gases are present in only air . non metals are available in solid form too
Water is held together by hydrogen bonds.
