Answer:

Proteins and nucleic acids

Explanation:

Nitrogen compounds in animals that are no longer of use, or are in access are excreted from the animals body, and are thus called nitrogenous waste. These nitrogenous waste can be excreted in three different ways.

1. Ammonia

2. Urea

3. Uric acid

Answer:

The answer to your question is 8.1 g of ZnCl₂

Explanation:

Data

mass of ZnCl₂ = ?

mass of Zn = 7.0 g

mass of CuCl₂ = 8 g

Balanced chemical reaction

                Zn  +  CuCl₂   ⇒   ZnCl₂  +  Cu

Process

1.- Calculate the molar mass of the reactants

Zn = 65.4 g

CuCl₂ = 63.6 + (35.5 x 2) = 134.6 g

2.- Calculate the limiting reactant

theoretical yield  CuCl₂ / Zn = 134.6/65.4 = 2.06

experimental yield CuCl₂ / Zn = 8/7 = 1.1

The limiting reactant is CuCl₂ because the experimental yield was lower than the theoretical yield.

3.- Use proportions to calculate the mass of ZnCl₂

molar mass of ZnCl₂ = 65.4 + (35.5 x 2) = 136.4 g

                  134.6 g of CuCl₂ ---------------- 136.4 g of ZnCl₂

                      8   g                 ----------------  x

                      x = (8 x 136.4) / 134.6

                      x = 8.1 g of ZnCl₂

Adding a(n) [Select]<br> ' will slow down a chemical reaction.
leva [86]

Inhibitor

Explanation:

Adding an inhibitor will slow down a chemical reaction. Inhibitors works like a negative catalyst.

The addition of a foreign body can influence the rate of a reaction.

  • When a foreign body slows down a reaction, it is called an inhibitor.
  • An inhibitor is a negative catalyst that will slow down a reaction.
  • Such substances do not allow a reaction to proceed freely and very fast.
  • They work in the opposite way a normal catalyst would.
  • It is good to know conditions and chemicals that can inhibit a chemical reaction.
