Cancer is a genetic disease—that is, it is caused by changes to genes that control the way our cells function, especially how they grow and divide. Genetic changes that cause cancer can happen because: of errors that occur as cells divide.
D. A force that acts between charged and uncharged particles. I think it’s D because the electrostatic force is the attractive or repulsive force between two electrically charged objects. D is the closest answer to the definition of electrostatic force
CO2 (s) + CO2 (g)
This is a physical change because only the state of matter changes, not the chemical makeup.
Answer: Hmmmmm that's crazy....
There are a couple of equations one could use for this type of problem, but I find the following to be the easiest to use and to understand.
Fraction remaining (FR) = 0.5n
n = number of half lives that have elapsed
In this problem, we need to find n and are given the FR, which is 1.56% or 0.0156 (as a fraction).
0.0156 = 0.5n
log 0.0156 = n log 0.5
-1.81 = -0.301 n
n = 6.0 half lives have elapsed

Just wanted to help. Hopefully it's correct wouldn't want to waster your time ;)
