Answer:
6
Explanation:
if you start with 12 atoms of carbon and its called the half life of carbon what is half of 12
Solubility,,,,,add water to the mixture,salt will dissolve to form a solution while sand is insoluble,,,,,decant the salt solution as filtrate and remain with sand as residue,,,,,if salt crystals are needed,,,,evaporate the filtrate to dryness.
The rate of a reaction is not affected by C) the magnitude of the equilibrium constant.
<h3>What is the rate of a reaction?</h3>
The rate of a reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time.
Let's consider which of the following factors affect the rate of a reaction.
- A) the concentration of the reactants. YES. The relationship between the concentrations of the reactants and the reaction rate depends on the reaction orders.
- B) presence of a catalyst. YES. Positive catalysts increase the reaction rate whereas negative catalysts decrease it.
- C) the magnitude of the equilibrium constant. NO. The equilibrium constant does not affect the reaction rate.
- D) the temperature of the reaction. YES. Usually, the higher the temperature, the faster the reaction.
- E) the surface area of the solid reactants. YES. The more surface area exposed to react, the faster the reaction.
The rate of a reaction is not affected by C) the magnitude of the equilibrium constant.

Answer:
0.1 M
Explanation:
Molarity = number of moles / litres of solution.
4 g of calcium bromide = 0.02 mol
(found by dividing 4 g by the atomic mass of CaBr2, which is 199.886)
200 mL of solution = 0.2 litres
Molarity = 0.02 mol / 0.2 L = 0.1 M
Answer:
keeping things above 40 degrees Celsius as that can fasten the rot process of fruits and vegetables
