The smell, the color change , change in temperature, it bubbles and it turns into a solid
Answer:physical: a part falling off or changing a tire. chemical:rust
Explanation:
Answer:
H^+(aq) + OH^-(aq) -------> H2O(l)
Explanation:
We must first write the molecular reaction equation as follows;
HNO3(aq) + NaOH(aq) ------>NaNO3(aq) + H2O(l)
The complete ionic equation is;
H^+(aq) + NO3^-(aq) + Na^+(aq) + OH^-(aq) -------> Na^+(aq) + NO3^-(aq) + H2O(l)
The net ionic equation therefore is;
H^+(aq) + OH^-(aq) -------> H2O(l)
Answer:
[H⁺] = 1.30X10⁻⁴ M
Explanation:
the problem will be solved by using Nernst's equation, which is :
In the given equation
n = 2
Q = ![=\frac{[Zn^{+2}][p_{H2}]}{[H^{+}]^{2}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5BZn%5E%7B%2B2%7D%5D%5Bp_%7BH2%7D%5D%7D%7B%5BH%5E%7B%2B%7D%5D%5E%7B2%7D%7D)
Putting values
![0.53= 0.76 - \frac{0.0592}{n}log(\frac{1X1}{[H^{+}]^{2}})](https://tex.z-dn.net/?f=0.53%3D%200.76%20-%20%5Cfrac%7B0.0592%7D%7Bn%7Dlog%28%5Cfrac%7B1X1%7D%7B%5BH%5E%7B%2B%7D%5D%5E%7B2%7D%7D%29)
on calculating
[H⁺] = 1.30X10⁻⁴ M
