K: 157.8g CaCl2
U: ? mol CaCl2
1Ca = 1(40.08) = 40.08
2 Cl = 2(35.45) =+ 70.90
110.98
157.8g CaCl2 1 mol CaCl2
1 mol CaCl2 110.98g CaCl2
Answer:
Not balanced
Explanation:
You have one sulfer and 6 oxygen on the left
You have one sulfer and 3 oxygen on the right
In order to balance it, you would need 2 sulfer and 6 oxygen on each side
The equation for that is:
2S + 3O2 → 2SO3
Answer:
Li3N
Explanation:
Li+N2=Li3N.........................
Explanation:
Because two sides don't have an equal number of O atoms. The left side has 6 O atoms (3*2) while the right side has only 1 O atom. to balance the equation, you need an equal number of atoms on both sides.
The combustion reaction of hexane:
2 C6H14 + 19 O2 = 12 CO2 + 14 H2O
2 mol C6H14 ---------> 12 mol CO2
x mol C6H14 ---------> 18.4 mol CO2
12 * x = 18.4 * 2
12 x = 36.8
x = 36.8 / 12
x = 3.067 moles of CO2
hope this helps!.
