Answer:
the sun beams down on the pool and heats it up top to bottom the deeper the colder
Answer:
C. A linear, nonpolar molecule
Explanation:
Molecules which are alike usually have the same degree of pull which results in them sharing electrons. This sharing of electrons is known as the molecules exhibiting Covalent bonding between them.
The equal pull also results in the cancelling out of electrons and favoring non polar bonds due to the absence of free electrons which would have been able to interact with H2O in a polar binding system.
The amount of water that could we get if you started with 250.0 grams of hydrogen is 2,250 grams.
<h3>What is moles - mass realation?</h3>
Moles (n) and mass of any substance are related to each other according to the given equation as:
n = W/M, where
W = given mass
M = molar mass
Given balanced chemical reaction is:
2H₂ + O₂ → 2H₂O
Moles of 250g of H₂ = 250g / 2g/mol = 125mol
From the stoichiometry of the reaction it is clear that,
2 moles of H₂ = produces 2 moles of H₂O
125 moles of H₂ = produces 125 moles of H₂O
Now mass of water will be calculated as:
Mass = (125mol)(18g/mol) = 2,250g
Hence required mass of water is 2,250 grams.
