Answer: Evaporation of salt water

Explanation: During the process of evaporating salt water which involves simple distillation, pure water is separated with salt molecules.

When heated water evaporates from the solution since it is less dense. When condensed it becomes pure water and salt is left out since it is more denser.

A student collects 629ml of oxygen at 0.500at, the student collected 0.0337 moles. At what temperature did the student collect t

VashaNatasha [74]

Answer:

114 K

Explanation:

Given data

Volume of oxygen (V): 629 mL = 0.629 L

Pressure of oxygen (P): 0.500 atm

Moles of oxygen (n): 0.0337 mol

Temperature (T): ?

We can calculate the temperature at which the student collected the oxygen using the ideal gas equation.

$P \times V = n \times R \times T\\T = \frac{P \times V}{n \times R} = \frac{0.500atm \times 0.629L}{0.0337mol \times 0.0821atm.L/mol.K} = 114 K$

The oxygen gas was collected at 114 K.

Answer:

The answer to your question is given below

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

Zn + 2HCl —> ZnCl2 + H2

Thus, we can write out the atoms present in both the reactant and the product by doing a simple head count. The atoms present are listed below:

Element >>> Reactant >>> Product

Zn >>>>>>>> 1 >>>>>>>>>> 1

H >>>>>>>>> 2 >>>>>>>>> 2

Cl >>>>>>>>> 2 >>>>>>>>> 2
