Thank you in advance <3

Answer 1

Answer:a

Explanation:just trust me

Answer 2

1. A) In chemical equilibrium The sign between the reactants and products is used to represent a chemical equilibrium. In a chemical equilibrium, the rate at which product is being produced is the same as the rate at which the product is being consumed to form the reactant again. 2 B) More products form This is in accordance to Le Chatelier's principle, which basically states that a reaction mixture at equilibrium will resist any change that is produced in it. Therefore, if the temperature is increased, the mixture will move towards the products side, which has a lower temperature due to it being an endothermic reaction. 3 A) Saturated When a solution is saturated, it is no longer able to dissolve any more solute within it. A crystal of solute sitting at the bottom is an indicator that no more solute can be dissolved, meaning the solution is saturated.
