1. Laughing gas (nitrous oxide, N2O) is sometimes used as an anesthetic in dentistry. It is produced when ammonium nitrate is decomposed according to the reaction
NH4NO3(s) −→ N2O(g) + 2 H2O(ℓ).
How much NH4NO3 is required to produce
29.7 g of N2O?
2. Carborundum (SiC) is a hard substance made
by combining silicon dioxide with carbon (C)
as follows:
SiO2(s) + 3 C(s) −→ SiC(s) + 2 CO(g).
What mass of SiC is formed from the complete reaction of 1.43 mol of carbon?
Answer in units of g

Your answer is a just took the test

The correct answer would be b) volume versus temperature, because they are also directly proportional.

Sink to the bottom. addition of potassium nitrate past it’s dissolution capacity at a particular temperature will cause the extra to just sink to the bottom of the glass.however, if you were to raise the temperature of the solution prior to dissolving it, and then slowly decrease the temperature after the dissolution, you would create a “supersaturated” solution - a solution that has more solute dissolved into it than should be allowed. if you add any extra solute past this, the entire solution would “crystallize,” and this is how you get those cool videos on youtube.

No, because shearing causes strike-slip faults and normal faults are caused by tension.
