The proper word equation for
4Fe + 3Sn(NO3)4 = 4Fe(NO3)3 + 3Sn is as below
Iron + Tin (iv) nitrate = iron(iii) nitrate + Tin
iron displaces tin from it compound ( Tin (iv) nitrate to form iron (iii) nitrate and tin.
from the equation above 4 moles of Fe displaces 3 moles of Sn(NO3)4 to form 4 moles of Fe(NO3)3 and 3 moles of SN

Explanation:
Both theoretical and actual yields would be needed to calculate percent yield.
The percent yield of a reaction is defined as the ratio of the actual yield to that of the theoretical yield. It can be mathematically expressed as:
percent yield = actual yield/theoretical yield x 100%
The actual yield is the amount of a specific product produced from a reaction while the theoretical yield is the stoichiometric amount of the same product.

E. Molarity of vinegar
i hope u get this i tried to figure it out hopefully im right
good luck!
Answer:
HCl solution - H30+ and Cl ions. pH 3
NaCl - Na+ and Cl-. pH 7
Explanation:
a) HCl solution - the hydrogen ion combines with water molecule to form the hydronium molecule which is responsible for acidity. The chloride ion is also found in solution.
pH = -log [H+] = -log(10^-3) = 3
b) NaCl 10-3 g. The solid dissocates in water forming the Na+ and Cl- ions. None of these ions affect pH
