Answer:
Explanation:
The step wise reaction mechanism for the formation of 1-methylcyclohexene is as follows.
I believe that east Texas is shaded green because it either has a grassy plain or there are a lot of grassy hills and I think that west Texas is shaded brown because it is like a desert.
a) (NH4)2SO4 --- 1 mole of it contains 2 moles of N, 8 moles of H, 1 mole of S, and 4 moles of O.
MM = (2 moles N x 14.0 g/mole) + (8 moles H x 1.01 g/mole) + (1 mole S x 32.1 g/mole) + (4 moles O x 16.0 g/mole) = 132 g/mole.
6.60 g (NH4)2SO4 x (1 mole (NH4)2SO4 / 132 g (NH4)2SO4) = 0.0500 moles (NH4)2SO4
b) The molar mass for Ca(OH)2 = 74.0 g/mole, calculated like (NH4)2SO4 above.
4.5 kg Ca(OH)2 x (1000 g / 1 kg) x (1 mole Ca(OH)2 / 74.0 g Ca(OH)2) = 60.8 moles Ca(OH)2
Answer:
Mass = 199.21 g
Explanation:
Given data:
Moles of HCl = 3.59 mol
Mass of CaCl₂ = ?
Solution:
Chemical equation:
2HCl + Ca(OH)₂ → CaCl₂ + 2H₂O
we will compare the moles of HCl with CaCl₂ from balanced chemical equation:
HCl : CaCl₂
2 : 1
3.59 : 1/2×3.59 = 1.795
3.59 moles of HCl will produced 1.795 moles of CaCl₂.
Mass of CaCl₂.
Mass = number of moles × molar mass
Mass = 1.795 mol × 110.98 g/mol
Mass = 199.21 g
