Answer:
3 is oxygen and ozone and 4 is only methane.
Explanation:
Note, a compound consists of 2 or more elements.
Answer:
The NH⁺₄ and SO₄²⁻ are spectator ions.
Explanation:
Chemical equation:
NH₄OH(aq) + H₂SO₄(aq) → (NH₄)₂SO₄(aq) + H₂O(l)
Balanced Chemical equation:
2NH₄OH(aq) + H₂SO₄(aq) → (NH₄)₂SO₄(aq) + 2H₂O(l)
Ionic equation:
2NH⁺₄(aq) + 2OH⁻(aq) + 2H⁺(aq) + SO₄²⁻(aq) → 2NH⁺₄ (aq) + SO₄²⁻(aq) + 2H₂O(l)
Net ionic equation:
2OH⁻(aq) + 2H⁺(aq) → 2H₂O(l)
The NH⁺₄ and SO₄²⁻ are spectator ions that's why these are not written in net ionic equation. The water can not be splitted into ions because it is present in liquid form.
Spectator ions:
These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
Answer:
Moles of Hydrogen produced is 5 moles
Explanation:
The balanced Chemical equation for reaction between zinc and sulfuric acid is :
![Zn(s) + H_{2}SO_{4}(aq) \rightarrow ZnSO_{4}(aq) + H_{2}(g)](https://tex.z-dn.net/?f=Zn%28s%29%20%2B%20H_%7B2%7DSO_%7B4%7D%28aq%29%20%5Crightarrow%20ZnSO_%7B4%7D%28aq%29%20%2B%20H_%7B2%7D%28g%29)
This equation tells that ; when 1 mole of Zn react with 1 mole of sulfuric acid, it produces 1 mole of zinc sulfate and 1 mole of hydrogen.
Since sulfuric acid is in excess so Zinc is the limiting reagent
(Limiting reagent : Substance which get consumed when the reaction completes, limiting reagent helps in predicting the amount of products formed)
Limiting reagent (Zn) will decide the amount of Hydrogen produced
![Zn(s) + H_{2}SO_{4}(aq) \rightarrow ZnSO_{4}(aq) + H_{2}(g)](https://tex.z-dn.net/?f=Zn%28s%29%20%2B%20H_%7B2%7DSO_%7B4%7D%28aq%29%20%5Crightarrow%20ZnSO_%7B4%7D%28aq%29%20%2B%20H_%7B2%7D%28g%29)
![1\ mole\ zinc\rightarrow 1\ mole\ H_{2}](https://tex.z-dn.net/?f=1%5C%20mole%5C%20zinc%5Crightarrow%201%5C%20mole%5C%20H_%7B2%7D)
So,
![5\ mole\ zinc\rightarrow 5\ mole\ H_{2}](https://tex.z-dn.net/?f=5%5C%20mole%5C%20zinc%5Crightarrow%205%5C%20mole%5C%20H_%7B2%7D)
Hence moles of Hydrogen produced is 5 moles
Answer:
I think it's B. Nonmetal
(I'm so sorry if it's wrong)
Hope this Helps!
Answer:
C5H12 + 8O2 → 6H2O + 5CO2
Explanation:
Pentane + Oxygen --> Water + Carbon dioxide
C5H12 + O2 --> H2O + CO2
The balanced equation is given as;
C5H12 + 8O2 → 6H2O + 5CO2
The principle is the law of conservation of matter that states that matter cannot be created nor destroyed. Hence, the reactants pretty much recombine to form the products.
The number of atoms remains conserved.
