Energy is needed to break the bonds of H-H in H2 and Cl-Cl in Cl2
Answer:
0.007 moles of octane
Explanation:
Balanced Equation: 2C₈H₁₈ + 25O₂ → 16CO₂ + 18H₂O
0.065 mol H₂O * 2 mol C₈H₁₈/18 mol H₂O = 0.00722... = 0.007 mol C₈H₁₈
Answer:
C₇ H₁₆ + 11O₂ → 7CO₂ + 8H₂O
Explanation:
Given equation
C₇ H₁₆ + O₂ → CO₂ + H₂O
To solve this problem,
We use a mathematical approach to balance the equation:
aC₇ H₁₆ + bO₂ → cCO₂ + dH₂O
Conserving C; 7a = c
H ; 16a = 2d
O: 2b = 2c + d
Let a = 1
c = 7
d = 8
b = 11
Now insert the parameters and solve;
C₇ H₁₆ + 11O₂ → 7CO₂ + 8H₂O
Answer
is: The molar solubility of calcium phosphate is 108s⁵ = Ksp.
<span>
Balanced chemical reaction: Ca</span>₃(PO₄)₂(s) → 3Ca²⁺(aq) + 2PO₄³⁻(aq).<span>
[Ca²</span>⁺] =
3s(Ca₃(PO₄)₂) =
3s.<span>
[PO</span>₄³⁻] = 2s.<span>
Ksp = [Ca²</span>⁺]³ · [PO₄³⁻]².<span>
Ksp = (3s)³ · (2s)².
Ksp = 108s</span>⁵.
s = ⁵√(Ksp ÷ 108).
