Fe(s) + 2hcl(aq) --> fecl2(aq) + h2(g)

when a student adds 30.0 ml of 1.00 m hcl to 0.56 g of powdered fe, a reaction occurs according to the equation above. when the reaction is complete at 273 k and 1.0 atm, which of the following is true?

a) hcl is in excess, and 0.100 mol of hcl remains unreacted.

d) 0.22 l of h2 has been produced.

the correct answer is d. i can't figure out why a is wrong.

Define the kinetic molecular theory

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
