Answer:

Explanation: Volume versus Temperature: Raising the temperature of a gas increases the average kinetic energy and therefore the rms speed (and the average speed) of the gas molecules. Hence as the temperature increases, the molecules collide with the walls of their containers more frequently and with greater force.

when the average kinetic energy of a gas increases, it causes the tempature to also Increase.

A student wants to make a 0.600 M aqueous solution of barium sulfate, BaSO4, and has a bottle containing 12.00 g of barium sulfa

love history [14]

<u>Answer: </u>The volume of the solution is 85.7 mL

<u>Explanation:</u>

Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:

$\text{Molarity of solution}=\frac{\text{Given mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (mL)}}$ .....(1)

We are given:

Molarity of solution = 0.600 M

Given mass of $BaSO_4$ = 12.00 g

We know, molar mass of $BaSO_4=[(1\times 137.33)+(1\times 32.07)+(4\times 16)]=233.4g/mol$

Putting values in equation 1, we get:

$0.600=\frac{12.00\times 1000}{233.4\times \text{Volume of solution}}\\\\\text{Volume of solution}=\frac{12.00\times 1000}{233.4\times 0.600}=85.68mL=85.7mL$

The rule of significant number that is applied for the problems having multiplication and division:

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

Here, the least number of significant figures is 3 that is determined by the number, 0.600. Thus, the answer must have these many significant figures only.

Hence, the volume of the solution is 85.7 mL

A. When calcium metal reacts with water, the gas evolved will not catch fire, but the same gas evolved on Potassium metal to wat

Phoenix [80]

Answer:

a. Due to the evolved hydrogen from potassium to water reaction being able to reach the flash point of the reaction temperature

b. Non-metal

The molecular formula is N₂O₃

Explanation:

a. The heat of the reaction between calcium and water is given as follows

Ca + 2 H₂O → H₂ + Ca(OH)₂ ΔH = -431.15 kJ which is exothermic, Entropy = -125.29 J/K

The heat of the reaction between potassium and water is given as follows

2 k + 2 H₂O → 2 KOH + H₂ ΔH = -393.15 kJ Entropy = 44.91 J/K

Therefore, the reaction between potassium and water occurs more vigorously than the reaction between calcium and water such that the flash point for the released hydrogen gas is reached in the case of potassium

b. The acidic oxides are oxides of metals or non-metals that react with water to produce an acid

Given the valence of the oxide which is +3, the oxide can be aluminium, Al or nitrogen, N, however, Al₂O₃ behaves both as an acid and a base, therefore, the likely candidate is nitrogen, which shows that X is a non-metal

The molecular formula is therefore;

N₂O₃
