A catalyst increases the rate of a reaction without being consumed. It accomplishes this by providing another mechanism that has

a lower activation energy.

Chemistry

sineoko [7]4 years ago
5 0

Answer: The given statement is true.

Explanation:

A catalyst is defined as the substance that lowers the activation energy of a chemical reaction without itself getting consumed so that there will be increase in rate of reaction.

As catalyst lowers the activation energy so, reactant molecules with lower energy also participates in the reaction. Hence, more collisions occur due to which there is rapid formation of products take place through another path.

Therefore, we can conclude that the statement a catalyst increases the rate of a reaction without being consumed. It accomplishes this by providing another mechanism that has a lower activation energy, is true.

1.5 moles are present in 60.0 grams of calcium.
Andrew [12]

Answer:

True.

Explanation:

To know which option is correct, let us calculate the number of mole present in 60g of calcium. This is illustrated below:

Mass of Ca = 60g

Molar Mass of Ca = 40g/mol

Number of mole Ca =....?

Number of mole = Mass/Molar Mass

Number of mole of Ca = 60/40

Number of mole Ca = 1.5 moles.

From the calculations made above, we can see that 1.5 moles are present in 60.0 grams of calcium

The mass of Fe(NO3)2 you have is 245 g * 0.805 = 197.23 g 

<span>The molar mass of Fe(NO3)2 is 179.85 g/mole so you have 1.0966 moles </span>

<span>From the balanced equation, that is the number of moles of Fe you make since both Fe(NO3)2 and Fe have a 3 in front of them. </span>

<span>The mass of Fe is 1.0966 moles * 55.85 g/mole (atomic mass of iron) = 61.246 g. From the information you are given, your answer should be in 3 sig figs so 61.2 g </span>

<span>Moles of HCl = 8.2 L * 3.5 mole/L = 28.7 moles </span>

<span>From the balanced equation, you need 1/2 the moles of zinc as you have of HCl so you need 14.35 moles. </span>

<span>To get the mass of zinc, multiply moles of zinc by its atomic mass = 938.2 g. From the information given, your answer should be in 2 sig figs so I would report it as 9.4 * 10^2 g, that clearly shows 2 sig figs.</span>

The heat energy required to change a unit mass of a solid into a liquid at constant temperature is called thermal equilibrium. 

'Equilibrium' means balance, and thermal is used to define temperature.
