Answer:I’m not 100% sure but I think it’s the first answer.
Explanation:
The pressure would increase as the molecules are pushing out word more and more, leading to more space being taken and more pressure. But then again, I’m not sure. I’m just a freshman with below average grades.
Explanation:
Notice the spikes, it increases on the top and decreases at the bottom
Molar mass NaCl = 58 g
Mass of solute = 29 g
number of moles: mass of solute / molar mass
n = 29 / 58
n = 0.5 moles

The orange would have more energy since it used it to grow while the pasta was baked causing all its energy to leave it
The combustion reaction of acetylene has a balanced equation
C2H2+3O2--->2H2O+2CO2
Using the ratio 1:3:2:2, if 1.10 mols of CO2 are produced, assuming complete combustion, than that means that 0.55 mols of acetylene (C2H2) must have been combusted. The molar mass of acetylene is 26, so the answer is 26*0.55 = 14.3 grams
