Answer:
We slip when we step on a banana peel because the inner side of banana peel being smooth and slippery reduces the friction between the sole of our shoe and the surface of road.
The answer is A. Increasing temperature of the reactants
Answer:
1.D) CH4 + 2O2 → CO2 + 2H2O
2C)2,1,2
3.D)SIO2 + 4HF → SIF4 + 2H2O
4.D)2As + 6NaOH → 2Na3AsO3 + 3H2
5.C)SiCI4 + 2H2O → SiO2 + 4HCI
Explanation:
equal number of atoms of each elements in both the sides of the chemical equation is required to have an equation in balanced state.
I think your answer is A not sure tho
Answer:
Fe²⁺ = 80mol/Ls
H⁺ = 50mol/Ls
Mn²⁺ = 4.0x10²mol/Ls
Fe³⁺ = 80mol/Ls
H₂O = 1.0x10²mol/Ls
Explanation:
Based on the reaction:
MnO₄⁻ + 5 Fe²⁺ + 8H⁺ → Mn²⁺ + 5 Fe³⁺ + 4H₂O
<em>Where 1 mole of permangante with 5 moles of Fe²⁺ and 8 moles of H⁺ produce 1 mole Mn²⁺, 5 of Fe³⁺ and 4 of H₂O</em>
<em />
If the diappearence of 1 mole has a rate of 4.0x10²mol/Ls, disappearence of 5 moles of Fe²⁺ and 8 moles of H⁺ have a rate of:
Fe²⁺ = 1 mole MnO₄⁻ × ( 4.0x10²mol/Ls / 5 moles of Fe²⁺) = 80mol/Ls
H⁺ = 1 mole MnO₄⁻ × ( 4.0x10²mol/Ls / 8 moles of H⁺) = 50mol/Ls
And rate of appearance of 1 mole Mn²⁺, 5 of Fe³⁺ and 4 of H₂O are:
Mn²⁺ = 1 mole MnO₄⁻ × ( 4.0x10²mol/Ls / 1 moles of Mn²⁺) = 4.0x10²mol/Ls
Fe³⁺ = 1 mole MnO₄⁻ × ( 4.0x10²mol/Ls / 5 moles of Fe³⁺) = 80mol/Ls
H₂O = 1 mole MnO₄⁻ × ( 4.0x10²mol/Ls / 4 moles of H₂O) = 1.0x10²mol/Ls
