1 mole of AGNO3 weighs 170g
so 0.6322 miles will weigh 170 X 0.6322=107.474 g
Answer:
Explanation:
Hello,
In this case, since the entropy of vaporization is defined in terms of the enthalpy of vaporization and the boiling point of the given substance, nitrous oxide, as shown below:
Solving for the boiling point of nitrous oxide, we obtain:
Which in degree Celsius is also:
Best regards.
Answer:
710,33 g NO2
Explanation:
2 C8H18 + 25 O2 → 16 CO2 + 18 H2O
(800 g octane) / (114.2293 g C8H18/mol x (25/2)) = 87.54 mol O2 used to combust the octane
= 15.44 mol O2 used to form NO2
O2 + 2NO → 2NO2
(15.44 mol O2) x (2/2) x (46.0056 g NO2/mol) = 710,33 g NO2
The simplified solubility of glucose at 30°C is 1.25 g/g of water. Considering that the density of water at 30°C is 1 g/mL, the equivalent mass of 400 mL of water is also 400g.
The concentration of the solution in water is,
550 g/400g of water = 1.375 g glucose / g of water
Since the concentration is higher compared to the solubility of glucose at the specified temperature, it can be said that the solution is SATURATED.
Acid precipitation should be a concern for the new age environmentalist, as they are one of the many consequences of a polluted and warming world, such is the one we live in. Acid precipitation comes from the evaporation of acid sea water, due to global warming and the fact that when more heat is trapped into the sea, more acid substance are released.

It can be answered by science because it is a question that is been solved via some experiments and it is in fact been proven recently as proofs correlates global waming with the acidification of the ocean and then acid rain. So this is a physic and environmental question, with ramification and consequences in other fields of science.

Acid precipitation in forests could affect the reproduction rate in birds. There are multiple factor that affect the reproduction rate in birds, and environment is one of the most complex and yet undiscovered. The two could have a potential entaglement as, for hyphotesis, acid precipitation could cause certain plant to die, and than the birds do not have a place where to reproduce.

It can be answered by science, via experiments and study. The relationship between environment and biology is a well-know correlation, so it does not represent a strech in this sense. Moreover, while it could be difficult to assure this for different reason, this is a problem that science could solve in different ways.
