Aqueous hydrobromic acid will react with solid sodium hydroxide to produce aqueous sodium bromide and liquid water . Suppose 17.

Marysya12 [62]

<u>Answer:</u> The mass of NaBr that can be produced is 6.3 grams

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$ .....(1)

<u>For HBr:</u>

Given mass of HBr = 17 g

Molar mass of HBr = 81 g/mol

Putting values in equation 1, we get:

$\text{Moles of HBr}=\frac{17g}{81g/mol}=0.210mol$

<u>For NaOH:</u>

Given mass of NaOH = 2.44 g

Molar mass of NaOH = 40 g/mol

Putting values in equation 1, we get:

$\text{Moles of NaOH}=\frac{2.44g}{40g/mol}=0.061mol$

The chemical equation for the reaction of HBr and NaOH follows:

$HBr+NaOH\rightarrow NaBr+H_2O$

By Stoichiometry of the reaction:

1 mole of NaOH reacts with 1 mole of HBr

So, 0.061 moles of NaOH will react with = $\frac{1}{1}\times 0.061=0.061mol$ of HBr

As, given amount of HBr is more than the required amount. So, it is considered as an excess reagent.

Thus, NaOH is considered as a limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

1 mole of NaOH produces 1 mole of NaBr

So, 0.061 moles of NaOH will produce = $\frac{1}{1}\times 0.061=0.061moles$ of carbon dioxide

Now, calculating the mass of NaBr from equation 1, we get:

Molar mass of NaBr = 103 g/mol

Moles of NaBr = 0.061 moles

Putting values in equation 1, we get:

$0.061mol=\frac{\text{Mass of NaBr}}{103g/mol}\\\\\text{Mass of NaBr}=(0.061mol\times 103g/mol)=6.28g$

Hence, the mass of NaBr that can be produced is 6.3 grams

BRAINLIESTTT ASAP! PLEASE HELP ME :)

Lisa [10]

The definition of potential energy is the energy that is absorbed within an object. The object is holding but not using the energy. In contrast, kinetic energy is the energy of motion so whenever something is moving it has kinetic energy.

The most classic example of going from potential to kinetic energy is the idea of a roller coaster. Once the roller coaster is going up towards a hill, it’s building up in potential energy. Once the coaster comes to the top of the hill, it contains total potential energy. And while the coaster begins to come down and pick up speed, this potential energy is being transferred as kinetic energy.

Hope that helps! :)
