_____NaOH + _____H2 SO4 _____ Na2SO4 + _____ H2O ,
To balance this equation,
Step 1:
Balance the number of sodium on both side:
by multiplying the NaOH by 2 that is:
2NaOH+H2SO4-------->Na2SO4+H2O
Step2:
As NOW the number of oxygen atom and hydrogen atom are not equal on both sides. So we multiply this H2O by 2 that is:
2NaOH+H2SO4-------->Na2SO4+2H2O
Now the no of all atoms on product side is equal to no of all atoms in the reactant side.
so the coefficient is 2 NaOH+1 H2SO4-------->1 Na2SO4+2 H2O.
Nₐ=6.02*10²³ mol⁻¹
n(Na₂O)=0.5 mol
n(Na⁺)=2n(Na₂O)
N(Na⁺)=n(Na⁺)Nₐ=2n(Na₂O)Nₐ
N(Na⁺)=2*0.5*6.02*10²³=6.02*10²³ ions
A solar panel works by talking in light and transforming it into energy and a windmill collects kinetic energy to transform it into energy.
Answer:
When our bodies are dry and wind blows by, we lose some energy to the air molecules. When are bodies are wet, we have a substance on our skin that likes to absorb heat. So when wind blows by, we lose a LOT of energy to the air molecules. When the body loses heat energy, our body temperature drops.

Answer:
A. The reaction will proceed forward forming more CH4
B. The reaction will proceed forward forming more CH4
C. Since the reaction is exothermic, raising the temperature will cause the reaction to proceed backward, thus forming C and H2.
D. Lowering the volume makes the gas particles to be more close together thereby enhancing their collisions leading to reaction. Therefore the reaction will proceed forward forming more CH4
E. Catalyst only reduce the activation energy so the reaction can proceed faster. The reaction will proceed forward forming.
F. The following will favour CH4 at equilibrium
i. Catalyst to the reaction mixture,
ii. Both adding more H2 to the reaction mixture and lowering the volume of the reaction mixture
iii. Adding more C to the reaction mixture.
