Answer:
See explanation
Explanation:
A balanced chemical reaction equation has the same number of atoms of each element on both sides of the reaction equation.
Hence, for the reaction between KOH and H2SO4, the balanced chemical reaction equation is;
H2SO4(aq) + 2KOH(aq) ---------> K2SO4(aq) + 2H2O(l)
Complete ionic equation;
2H^+(aq) + SO4^2-(aq) + 2K^+(aq) +2OH^-(aq) -------> SO4^2-(aq) + 2K^+(aq) + 2H2O(l)
Net ionic equation;
2H^+(aq) + 2OH^-(aq) -------> 2H2O(l)
Answer:
denotes the molar hydrogen ion concentration
Explanation:
The balance equation is :
<span>SO2 + CaO → CaSO3
</span>
1.
<span>(2100 tons) x (0.025 S) / (32.0655 g S/mol) x (1 mol SO2 / 1 mol S) x </span>
<span>(1 mol CaO / 1 mol SO2) x (56.0778 g CaO/mol)
= 91.81 tons CaO
</span>
2. <span>(2100 tons) x (0.025 S) x (907185 g/ton) / (32.0655 g S/mol) x (1 mol SO2 / 1 mol S) x </span><span>(1 mol CaSO3 / 1 mol SO2) x (120.1422 g CaSO3/mol)
= 1.784 x 10^8 g CaSO3</span>
Answer:
Covalent-network (also called atomic) solids—Made up of atoms connected by covalent bonds; the intermolecular forces are covalent bonds as well. Characterized as being very hard with very high melting points and being poor conductors. Examples of this type of solid are diamond and graphite, and the fullerenes.
