4HCl + MnO₂ → MnCl₂ + 2H₂O + Cl₂
2Cl⁻ → Cl₂ + 2e⁻
MnO₂ + 4H⁺ + 2e⁻ → Mn²⁺ + 2H₂O
2Cl⁻ + MnO₂ + 4H⁺ → Cl₂ + Mn²⁺ + 2H₂O
The heat released : -110560.632 J
<h3>Further explanation</h3>
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
<h3>Known</h3>
m =465 g
c water = 4.186 J/gram °C
∆T = temperature difference = 18.2 - 75 = - 56.8 °C
Then the heat :

Answer:
B
Explanation: Lithium, sodium, and potassium, etc. all react with water
Explanation:
Adding logs of same base is equivalent to multiplying the arguments. You get:

Use the definition of the log to turn this into an exponential function:
