The process of a chemical change is when it occur when a substance called chemical synthesis or alternatively chemical decomposition into two or more different substances
Answer:
b. has a low specific heat capacity.
Explanation:
Hello,
In this case, since the specific heat is defined as the heat required to increase or decrease 1 degree Celsius 1 gram or mole of a specific substance, we infer that the lower the specific heat, the less energy will be needed for such increase or decrease, therefore, it turns out easier to modify the temperature in a substance that b. has a low specific heat capacity.
Best regards.
Answer: It increases the reaction rate.
Step-by-step explanation:
The particles gain kinetic energy.
Answer:
pH = 5.47
Explanation:
The equilibrium that takes place is:
HIO ↔ H⁺ + IO⁻
Ka = ![\frac{[H+][IO-]}{[HIO]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BH%2B%5D%5BIO-%5D%7D%7B%5BHIO%5D%7D)
= 2.3 * 10⁻¹¹
At equilibrium:
<u>Replacing those values in the equation for Ka and solving for x:</u>
Then [H⁺]=3.39 * 10⁻⁶, thus pH = 5.47
