Question

chemistry problem, should be easy

Answer 1

What coefficients must be added to balance the following equation?

_____LiOH + _____H2 SO4 yields _____ Li2SO4 + _____ H2O

2, 1, 1, 1,
3, 1, 1, 3
2, 1, 1, 2
4, 2, 2, 1

Answer 2

first count the number of each atom on the reactant side: then the product side.,

Answer 3

ok

Answer 4

Reactants:
Li - 1
O - 1
H - 3
SO4 - 1

Products:
Li - 2
O - 1
H - 2
SO4 - 1

Answer 5

Using the first combination: 2LiOH + 1H2SO4 ---> 1Li2SO4 + 1H2O

Reactants:
Li - 2
O - 2
H - 4
SO4 - 1

Products:
Li - 2
O - 1
H - 2
SO4 - 1
That one doesn't work because the reactants and products aren't balanced

Using the second combination: 3LiOH = 1H2SO4 ---> 1Li2SO4 + 3H2O

Reactants:
Li - 3
O - 3
H - 5
SO4 - 1

Products:
Li - 2
O - 3
H - 6
SO4 - 1
That one also doesn't work because the reactants and products aren't balanced

Answer 6

Using the third combination: 2LiOH + 1H2SO4 ---> 1Li2SO4 + 2H2O

Reactants:
Li - 2
O - 2
H - 4
SO4 - 1

Products:
Li - 2
O - 2
H - 4
SO4 - 1
This one works, but let's check the last one just in case

Using the fourth combination: 4LiOH + 2H2SO4 ---> 2Li2SO4 + 1H2O

Reactants:
Li - 4
O - 4
H - 8
SO4 - 2

Products:
Li - 4
O - 1
H - 2
SO4 - 2
The one doesn't work because the reactants and products aren't balanced.
