Protons + and electrons - must be equal
3 moles of C has a mass of 36, 3 moles of He is 12
so the answer is :
The carbon sample would have three times the mass of the helium sample
hope this helps
Answer: when two atoms do not share electrons equally in a covalent bond.
Explanation:
Less water = less weight to make it rise
More water = more weight to make it dive
Answer:
Explanation: S + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O In the above equation how many moles of water can be made when 115.3 grams of HNO3 are consumed? Round your answer to the nearest tenth. If you answer is a whole number like 4, report the answer as 4.0 Use the following molar masses. If you do not use these masses, the computer will mark your answer incorrect.: Element Molar Mass Hydrogen 1 Nitrogen 14 Sulfur 32 Oxygen 16...

Explanation:
Vapor pressure is defined as the pressure exerted by vapors or gas on the surface of a liquid.
When interaction between the solute and solvent are weak then solution will evaporate readily into the atmosphere. Therefore, it means vapor pressure increases with particularly weak solute-solvent interactions.
On the other hand, when interactions between the solute and solvent of a strong enough in a solution then vapors are not formed easily. This also means that vapor pressure decreases with particularly strong solute-solvent interactions.
