1) HClO4 Strong acid. It will be represented in ionic form in aqueous solution
2) HNO2 weak acid
3) HF weak acid
4) HCN weak acid
a) Oxidised. Oxygen transferred from CuO to Zn.
b) Reduced. Oxygen transferred from Iron oxide to Carbon.
c) Oxidised. Electrons transferred to
d) Reduced. Electrons are gained by $\mathrm{Cu^{+2}}$
Mm = #g / #mol --> 56.2g / 0.492 mol
mm = 114.2g/mol
Answer:
1.14 M
Explanation:
grams/molar mass = ans. / volume
317/110.98=2.86/2.50=1.14 M
