solubility of CO2 decreases as water temperature increases. tis cuz' CO2 molecules get heated up w water. they move faster when heated n more OC2 molecules leave the water n its solubility decreases.
Answer:
(5.50) ( 6.02 *10^23)
Explanation:
The number of molecules equals the number of moles times Avagadro's number.
It's between br and si so id go with br
The reactions based on the absorption and release of the energy are called endothermic and exothermic reactions. The reaction is exothermic.
<h3>What is an exothermic reaction?</h3>
Exothermic reactions are the reaction in which the reactant produces products that release energy from the system to the surroundings. In the reaction bond energy of the reactant is less than the product.
Energy from the system is released in the form of heat, sound, light and electricity. The weak bonds of the compounds are replaced with stronger ones and the standard enthalpy of the reaction is negative.
Therefore, option c. reaction is exothermic is correct.
