Answer:
The correct answer would be C) Support
Chemical Property
<u>Explanation:</u>
When a substance is changed into another substance, may be due to addition of some other substance or removal of water from that substance.
* its identity changes
*its reactivity changes
*reactivity towards water, air and many other substances will change
*its chemical composition changes
and all these changes occurs due to the chemical properties.
If the physical property changes then there will be change in the state of matter, but its boiling point, melting point , reactivity towards water, air and other substances will not change, and it will not lose its identity.
Answer: 8.38 seconds
Explanation:
Integrated rate law for second order kinetics is given by:
= initial concentartion = 0.860 M
a= concentration left after time t = 0.230 M
k = rate constant =
Thus it will take 8.38 seconds for the concentration of A to decrease from 0.860 M to 0.230 M .
