I would research the job of being a fitness coach, that is very popular in health and fitness
you are given the number of moles, from the given formula you can get the molar mass which is 12.00g/mol + 16 g/mol =28 g/mol. using the formula n=m/Mr rearrange the formula and make m subject, you thn have m=nMr therefore 7.60x 1021 mol x 28g/mol= m
m = 217268.8 g, you will notice that mol cancel out each other leaving you with g.
now convert g to litres
1 litre is equal to 1000 grams therefore
217268.8g x 1l/1000g = 217,269 litres
The answer is A because water can only evaporate if a liquid substances becomes gas , in this case it’s the water. When water is heated it evaporates. The molecule moves and vibrates so quickly that they can move to the atmosphere
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.
