Solids' particles move a lot faster and closer together. Liquids' are more spread apart and move slower. So there is more energy in the solid
The total number of moles of NaOH needed to react : 4
<h3>Further explanation</h3>
Given
Reaction
2NaOH + H2SO4 → Na2SO4 + 2H2O
Required
moles of NaOH
Solution
The chemical reaction coefficient shows the mole ratio of the components of the compounds involved in the reaction, either in terms of reactants or products
From the equation, mol ratio of NaOH and H2SO4 : = 2 : 1, so mol NaOH :
= 2/1 x mol H2SO4
= 2/1 x 2 moles
= 4 moles
Answer:
Yes, yield.
Explanation:
N2(g) + 3 H2(g) → 2 NH3 (g) balanced equation
First, find limiting reactant:
Moles H2 = 1.83 g x 1 mole/2 g = 0.915 moles H2
Moles N2 = 9.84 g N2 x 1 mole/28 g = 0.351 moles N2
The mole ratio of H2: N2 is 3:1, so H2 is limiting (0.915 is less than 3 x 0.351)
Theoretical yield of NH3 = 0.915 mol H2 x 2 mol NH3/3 mol H2 = 0.61 moles NH3

At first sight, I could recognize you
As if we were calling for each other
The DNA in my blood vessels tell me
That it’s you I was looking all over for
Not sure about any others but I believe 3 goes with B
