In the reaction below, 150.0 g of water is collected. how many liters of sulfuric acid were used if the concentration is 0.650 m? h2so4 + na2co3 → na2so4 + co2 + h2o 1. 17.0 l 2. 0.670 l 3. 4.23 l 4. 12.8 l 5. 4130 l 6. 10.6 l

Answer is: 12,8 l of H₂SO₄.
Chemical reaction: H₂SO₄ + Na₂CO₃ → Na₂SO₄ + CO₂ + H₂O.
m(H₂O) = 150 g.
c(H₂SO₄) = 0,650 mol/dm³.
V(H₂SO₄) = ?
n(H₂O) = m(H₂O) ÷ M(H₂O) 
n(H₂O) = 150 g ÷ 18 g/mol = 8,33 mol.
from reaction: n(H₂SO₄) : n(H₂O) = 1 : 1.
n(H₂SO₄) = 8,33 mol.
c = n ÷ V, V = n ÷ c.
V(H₂SO₄) = 8,33 mol ÷ 0,650 mol/dm³ = 12,81 dm³.

The answer is c) pyrite

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
