It's not oxygen production. The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet's living systems are powered by this process.
Explanation:
The answer is TRUE chemical changes do involve breaking and the making of chemical bonds.
Answer:
The answer is given below:
Explanation:
Strong acids have the ability to dissociate quickly as compared to the weak acids which dissociates slowly and can do that up to a certain level.
HCl is a strong acid and HA as stated in the statement is a weak acid.
So, in the beaker which contains HCl will have:
In the beaker with HA will have:
% mass Na = (g Na / g H2O) x 100
<span>g Na = (% mass Na)(g H2O) / 100 = (5.2 x 10^-4 g Na / g H2O) </span>
<span>2.4 g Na x (1 g H2O / 5.2 x 10^-4 g Na) = 4600 g Na </span>
<span>4600 g Na x (1 mL H2O / 1 g H2O) = 4600 mL H2O = 4.6 L H2O which is a little more than a gallon</span>
