Answer:
1.17%
Explanation:
The pressure using vander waals' equation = 610.955atm
The difference
- 610.955-494.4 =116.555atm
The % difference = 1.17%
Answer:
<u>4</u>H₂O(l) →<u> 4</u>H₂(g) + <u>2</u>O₂(g)
Balancing equations
1. 3Fe(s) + 4H₂O(g) → Fe₃0₄(s) + 4H₂(g)
2. 2AlBr₃(aq) + 3Cl₂(g) → 2AlCl₃(aq) + 3Br₂(l)
3. 2HNO₃(aq) + Ba(OH)₂(aq) → Ba(NO₃)₂(aq) + 2H₂O(l)
4. 2Al(s) + 3Pb(NO₃)₂ → 2Al(NO₃)₃(aq) + 3Pb(s)
5. 3NaOH(aq) + Fe(NO₃)₃ → Fe(OH)₃(s) + 3NaNO₃(aq)
Explanation:
From the question given, I have been able to balance the chemical equations correctly.
In balancing chemical equations, the chemical equation must have equal number of atoms for each element that are both in the reactant side and in the product side.
For the above to be achieved, the number of atoms in each element will have to be multiplied and added.
A look at the balanced chemical equation above, you will discover that each element has the same number of atoms both in the reactant side and in the product side.
Answer:
<h2>3.18 × 10²³ atoms</h2>
Explanation:
The number of atoms can be found by using the formula
N = n × L
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 0.529 × 6.02 × 10²³
We have the final answer as
<h3>3.18 × 10²³ atoms</h3>
Hope this helps you
BaCl₂(aq) + Na₂SO₄(aq) = BaSO₄(s) + 2NaCl(aq)
Ba²⁺(aq) + 2Cl⁻(aq) + 2Na⁺(aq) + SO₄²⁻(aq) = BaSO₄(s) + 2Na⁺(aq) + 2Cl⁻(aq)
Ba²⁺(aq) + SO₄²⁻(aq)= BaSO₄(s)
