Answer:
In acid – base chemistry, salts are ionic compounds that result from the neutralization reaction of an acid and a base. Basic salts contain the conjugate base of a weak acid, so when they dissolve in water, they react with water to yield a solution with pH greater than 7.0.

Answer:
500 years
Explanation:
The original carbon-14 was 100%, and after 100 years, it decays 1.202%. So after 100 years it goes to 98.798%, after more 100 years (200 years), it will be 97.596% (98.798 - 1.202), thus, after n 100 years "package", the percenatge will be:
100% - actual% = n*1.202
n = (100% - actual%)/1.202
n = (100% - 94%)/1.202
n = 4.992
So, the number of years is n*100 = 4.992*100 = 499.2 ≅ 500 years.
Answer:
See below.
Explanation:
It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's.
