Chemistry Honors:
Calculations Involving a Limiting Reactant
For each of the following unbalanced chemical equations, suppose that exactly 5.00 g of each reactant is taken. Determine which reactant is limiting, and calculate what mass of each product is expected (assuming that the limiting reactant is completely consumed).
S(s) + 2H2SO4(aq) --> 3SO2(g) + 2H2O(l)

Answer 1

h2so4 is the limiting reagent ....
since moles of h2so4 are 5/196 and moles of s is 5/32
therrfore moles of h2so4 less than moles of s
and using this u can further cal mass of so2 and h20 my using proper molar ratio

Answer 2

For stoichiometry-:
check two things...
1)the equation shd be balanced.
2) U have to determine u've to find the product formation or reactant available.
If product formation is confirmed then finding limiting reagent shd be the first step, rest is simple unitary method.
stoichiometry is about law of conservation of mass actually.

Answer 3

i still dont get it can u guys explain please?

Answer 4

like do the problem for me?

Answer 5

where ru facing the problem?

Answer 6

yes for an hour actually and i still don't get it.. i thought i did but when i looked at the answer from the back of the book it was wrong :(

Answer 7

is the ans for so2 4.89 and for h20 0.46 g ?

Answer 8

no, it was 4.52 and .989 or something..
