Answer:
The answers to the questions are given below.
Explanation:
According to Le Chatelier's principle, if an external constrain such as change in concentration, temperature or pressure is imposed on a chemical system in equilibrium, the equilibrium will shift in order to neutralize the effect.
A. Effective of removing ammonia, NH3.
N2(g) + 3H2(g) ⇌ 2NH3(g)
Removing NH3 from the reaction simply means we are left with more reactants and no product. Therefore, the reactant will react to produce the product. Hence, the equilibrium position will shift to the right.
2. Effect of removing H2
N2(g) + 3H2(g) ⇌ 2NH3(g)
Remoing H2 simply means we have more products and less reactant. Therefore, the product will be convert to reactant. Hence, the equilibrium position will shift to the left.
C. Effect of adding a catalyst.
N2(g) + 3H2(g) ⇌ 2NH3(g)
Catalyst does not affect the equilibrium position. It only creates an alternative path to arrive at the product within a short time. Hence, it has no effect.
D. Rock because it is not living
Answer:
beakers and flasks
Explanation:
its better to use accurate measuring instruments for measuring volume
Answer:
See explaination for details and diagram
Explanation:
We can say that Chemical reaction is a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds.
A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
