I think it might be Core Electrons and Valence Electrons respectively. As core electrons are the name of the electrons for the inner levels. While valence is the outer shell electrons.
Economic concerns is the correct one
Answer:
the mass of each gas
Explanation:
Two balloons hold two different gases. The gases are held at the same pressure, volume, and temperature. Which quantity can differ between
the two gases?(1 point)
the gas constant of each gas
the molar volume of each gas
the mass of each gas
Two balloons hold two different gases. The gases are held at the same pressure, volume, and temperature. Which quantity can differ between the two gases?(1 point) the gas constant of each gas the gas constant of each gas the molar volume of each gas the molar volume of each gas the mass of each gas the mass of each gas the number of moles of each gas
the number of moles of each gas
PV = nRT
The gases have the same P.V, T and n
R is constant AND SO constant for both
the only difference is the molar mass of the gas
for the same number of moles, the balloons will have different weights depending on the gas
so the answer is
the mass of each gas
Answer:
Number of moles = 0.003 mol
Explanation:
Given data:
Molarity of HCl = 0.300 M
Volume = 10.0 mL (0.01 L)
Number of moles of HCl added = ?
Solution:
Formula:
Molarity = number of moles / volume in litter
Number of moles = Molarity × volume in litter
Number of moles = 0.300 mol/L × 0.01 L
Number of moles = 0.003 mol
Answer:
10 moles
Explanation:
The first thing to do is to write the balance chemical reaction
According to the balanced chemical equation, if the hydrochloric acid is in excess, one mol of iron forms one mole of iron (II) chloride, which is as many moles as iron. So 10 moles of iron will form 10 moles of iron (II) chloride.
