Answer:
provide rewards to use solar power
Explanation:
Using solar power we can avoid bad energy like Coal, oil, natural gas, uranium and water from a dam.
All these kinds of energy producing air pollution, water pollution, or greenhouse gases.
But solar power has some toxic materials, also, using a lot of water to keep and clean solar power. In addition, if we create a solar power near a river or lake may cause damage.
We must think in these factors before to do a solar power.
Na₂SO₄ → 2Na⁺ + SO₄²⁻
c₁(Na⁺)=2c(Na₂SO₄)
n₁(Na⁺)=c₁(Na⁺)v₁=2c(Na₂SO₄)v₁
NaCl → Na⁺ + Cl⁻
c₂(Na⁺)=c(NaCl)
n₂(Na⁺)=c₂(Na⁺)v₂=c(NaCl)v₂
n(Na⁺)=n₁(Na⁺)+n₂(Na⁺)=2c(Na₂SO₄)v₁+c(NaCl)v₂
v=v₁+v₂
c(Na⁺)=n(Na⁺)/v={2c(Na₂SO₄)v₁+c(NaCl)v₂}/(v₁+v₂)
c(Na⁺)={2*0.400*0.1+0.600*0.2}/(0.1+0.2)=0.667 mol/L
c(Na⁺)=0.667M
