Answer : The pressure at this new altitude is, 364.2 mmHg
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
![P\propto \frac{1}{V}](https://tex.z-dn.net/?f=P%5Cpropto%20%5Cfrac%7B1%7D%7BV%7D)
or,
![P_1V_1=P_2V_2](https://tex.z-dn.net/?f=P_1V_1%3DP_2V_2)
where,
= initial pressure = 760 mmHg
= final pressure = ?
= initial volume = 62.3 L
= final volume = 130 L
Now put all the given values in the above equation, we get:
![760mmHg\times 62.3L=P_2\times 130L](https://tex.z-dn.net/?f=760mmHg%5Ctimes%2062.3L%3DP_2%5Ctimes%20130L)
![P_2=364.2mmHg](https://tex.z-dn.net/?f=P_2%3D364.2mmHg)
Thus, the pressure at this new altitude is, 364.2 mmHg
Out of the four answers, only increasing the temperature will speed up the dissolution rate. The 4th option will increase the total amount of solute that can be dissolved but will not affect the dissolution rate. The 1st and 3rd options are just wrong.
The density of a 167.4 g sample of magnesium having a volume of 96.32 ml is <u>1.737 g/cm3.</u>
<h3>What is density?</h3>
The mass per unit volume is known as density. A scalar quantity, density. It is represented by the letter D, and the Greek letter rho is used as the sign for density. Mass divided by volume is how density is computed.
Mass is a physical body's total amount of matter. Mass is defined as the sum of the moles of the material and the compound's molar mass.
Given the mass is 167.4 g
The volume is 96.32 ml
mass / volume
167.4 / 96.32 = 1.737
Thus, the density of a 167.4 g sample of magnesium is 1.737 g/cm3.

Answer:
Total pressure of the mixture is 12.2 atm
Explanation:
Let's apply the Ideal Gases law to solve this
Total pressure . V = Total moles . R . T
Total moles = 0.4 m of He and 0.6 mole of Ne → 1 mol
P . 2L = 1 mol . 0.082 L.atm/mol. K . 298K
P = ( 1 mol . 0.082 L.atm/mol. K . 298K) /2L
P = 12.2 atm
Answer: product
Explanation:
Each substance written to the right of the arrow in a chemical equation is referred to as a product.
When writing a chemical equation, the substance that's written to the left of arrow in the equation is the reactants.
On the other hand which is the right side is the product.
