Answer:
fe3o4+4h2 - 3fe + 4h2o
therefore coefficient is 4
I can if you give man example I'll show you how to do it.
Answer:
5.52cm³ of water will rise and might spill over the edge
Explanation:
Use the change in volume of a liquid with changing temperature equation which is written as
ΔV = β x V₀ x ΔT, where β is the coefficient of expansion, V₀ is the volume being submerged and ΔT is the difference in temperature
ΔV = (69 x 10⁻⁶) x (0.1 x 0.1 x 0.1) x (85 - 5)
ΔV = 5.52 x 10⁻⁶ m³
ΔV = 5.52cm³
Answer:
11.22 gm
Explanation:
32.07 gm / mole * .350 mole = 11.22 gm
2H2+O2→2H2O
We have to be aware that the number of atoms are the same on both reactant side and product side.
