2CH₃COOH(aq) + Zn(s) → Zn(CH₃COO)₂(aq) + H₂(g)
2CH₃COOH(aq) + BaO(s) → Ba(CH₃COO)₂(aq) + H₂O(l)
CH₃COOH(aq) + NaOH(aq) → CH₃COONa(aq) + H₂O(l)
C=2
D=2
the correct ansssssssssssswwwwwwwwwwwwwweeeeeeeeeeeeeerrrrrrrrrrrr
answer
The best equation which illustrate the law of conservation of mass is
Zn +2 HCl --> ZnCl2 + H2
This is because the mass of the product is equal to the mass of reactant. for example the mass of Zn is 1 in the reactant and product side. According to the law of mass conversation the mass in a isolated system is neither created nor destroyed by chemical reaction or physical transformation
Answer:
18moles of H20
Explanation:
C5H12 + 8O2 —> 5CO2 + 6H2O
From the balanced equation,
1mole of C5H12 were consumed to produce 6moles of H2O.
Therefore, if 3 moles of C5H12 were consumed, it will produce = 3 x 6 = 18moles of H20
Answer:
Final concentration = 0.019 M
Explanation:
Initial Concentration [A]o = 0.27M
Rate constant, k = 0.75 s^-1
Final concentration [A] = ?
Time, t = 1.5s
The relationship between the variables is given by the equation;
ln[A] = ln[A]o - kt
ln[A] = ln(0.27) - (0.75)(1.5)
ln[A] = - 1.309 - 1.125
ln[A] = - 2.434
[A] = 0.019 M
