Answer:
A
Explanation:
its A because of how oxygen can come out of plants during the time of photosynthesis
Answer:
8.909*10^-4 moles
Explanation:
The mixture contains MgCl
and NaCl with a total mass of 0.4015 g. The mass of precipitate AgCl(aq) is 1.032 g and it has a molar mass of 143.32 g/mol. Therefore, the moles of the precipitate is:
n = 1.032/143.32 = 7.2007*10^-3 moles
Molar mass of NaCl = 58.44 g/mol and the molar mass of MgCl
is 95.21 g/mol. Let the mass (g) of MgCl
in the original mixture be 'x'. Thus:
7.2007*10^-3 = (0.4015-x)/58.44 + 2x/95.21
(7.2007*10^-3)*58.44*95.21 = 95.21(0.4015-x) + 2x(58.44)
40.06505 = 38.227 -95.21x + 116.88x
40.06505 - 38.227 = -95.21x + 116.88x
1.83805 = 21.67x
x = 1.83805/21.67 = 0.0848 g
moles of MgCl
= 0.0848g/95.21 g/mol = 8.909*10^-4 moles
It's formed by the hydrogen ion of the acid and the hydroxide of the base.

Sulfuric Acid + potassium superoxide --> Potassium Sulfate + Heavy Water
Hope this Helps :)
I don't know what you mean by just good, but electricity wise, no. In electricity they can't conduct very well and are just so called "heat carriers." They also have higher melting and/or boiling points. I found most of this on google so if you still are lost try looking up your question. Good luck! :)
