Answer:
The total mass of the reactants is <u>equal to </u> the total mass of the products in a chemical reaction.
Explanation:
Answer & Explanation:
- The neutralization of H₂SO₄ with NaOH is occurred according to the balanced equation:
<em>H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O,</em>
It is clear that every 1.0 mol of H₂SO₄ needs 2 mol of NaOH to be neutralized completely.
<em>So, when you mix one mole of sulfuric acid with 1 mole of sodium hydroxide, there will be an excess of sulfuric acid.</em>
<em>Thus, the pH of the solution remain below 7.</em>
Newton's first law is the answer.
When an iron is dipped in Copper Sulphate
Solution this reaction between them and
copper sulphate change into blue color to light
green color. This show that iron is more
reactive then copper, it can to replace copper
from CuSO4 , CuSO4 is of blue color and
FeSO4 is light green color.
