Explanation:
<span>The atmosphere is a thin layer of gases that surrounds the Earth. It seals the planet and protects us from the vacuum of space. It protects us from electromagnetic radiation given off by the Sun and small objects flying through space such as meteoroids.</span><span>
So it's like a blanket protecting us but it has air hole/patches where sunlight can get through</span>
Answer:
Concentration of the reactants decreases;
Rate of a reaction decreases
Explanation:
Since volume is held constant in a solution, the concentration of the reactants will decrease.
Simply speaking, concentration is the ratio between moles and volume. Volume is constant here. Over time, the number of moles of the reactants will decrease, as they react to produce products and they are disappearing. Since moles are directly proportional to concentration, this implies that concentration will also decrease, while the concentration of the products will increase, as they're formed.
The rate of a reaction decreases as the reaction continues, as we have lower and lower amounts of the reactants remaining in the solution as time progresses. Therefore, the probability of a successful collision leading to products decreases.
Answer:
Equilibrium position shifts right.
Explanation:
According to Le Châtelier's principle, when a chemical system at equilibrium is distributed by a change in conditions, the equilibrium position will shift in a direction that tends to counteract the change.
So, when the concentration of reactant increases, the equilibrium will counteract the change by increasing the concentration of the products, hence shifting right to increase the concentration of water.
