What is the limiting reactant in each of the following reactions?
a 0.1 mol Sb. O react with 0.5 mol H2SO4
Sb.06 +6H2SO4 → 2Sb2(SO4)3 + 6H2O
b 0.20 mol AsClz react with 0.25 mol H2O
4AsCl3 + 6H2O → As 06+12HCI
c 0.25 mol copper react with 0.50 mol dilute
HNO3 according to the equation:
3Cu+8HNO3
→ 3Cu(NO3)2 + 4H2O+2NO
d 0.10 mol NaCl react with 0.15 mol MnO2 and
0.20 mol H2SO4
2NaCl + MnO2+2H2SO4
→ Na2SO, +MnSO4 +2H2O + Cl2

- decrease the number of plants and animals living in the water.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
