Please, please, please answer!! This is due today! For each of the following unbalanced chemical equations, suppose 10.0 g of each reactant is taken. Show by calculation which reactant is the limiting reagent. Calculate the mass of each product that is expected.

a. C3H2(g) + O2(g) → CO2(g) + H2O(g)

b. Al(s) + Cl2(g) → AICI3(s)

c. NaOH(s) + CO2(g) → Na2CO3(s) + H2O(1)

d. NaHCO3(s) + HCl(aq) - NaCl(aq) + H2O(l) + CO2(g)​

What do you need with it’s not a question your just stating what it says

Radon-222 or rn-222 has a half-life of 3.82 days. to determine the fraction of an original sample of rn-222 that remains unchanged after 7.646 days, we calculate the amount of rn-222 remaining after 7.646 days and divide it with the original amount. using 1 gram as a basis and using half-life calculation methods, we can determine that  0.249 or 0.25  grams of rn-222 will remain, and thus the fraction remaining is 0.25 or 1/4.
