1. Why is it necessary to equalize the pressure(i.e, have the water level the same in each tube) before taking a volume reading?

Answer:

If you contact water with a gas at a certain temperature and (partial) pressure, the concentration of the gas in the water will reach an equilibrium ('saturation') according to Henry's law.

Explanation:

This means: if you increase the pressure (e.g. by keeping the vial closed), the CO2 concentration will increase. So it simply depends what concentration you need for your assay: 'CO2-saturated' water at low pressure or 'CO2-saturated' water at high pressure.

Is exposure to oxygen a type of mechanical weathering
evablogger [386]
Weathering is the name given to the process of breaking-down rocks at Earth's surface. This is accomplished due to the exposure to oxygen through the process of oxidation and to the exposure to water in its various forms (liquid, solid, & gas). ... Water is the primary agent for mechanical weathering.

What is the volume of 1.50 lb (pounds) of mercury? The density of mercury is 13.546 g/mL. Use the conversion that 1 kg = 2.20 lb
Arada [10]

Answer:

50.3mL of mercury are in 1.50lb

Explanation:

Punds are an unit of mass. To convert mass to volume we must use density (13.546g/mL). Now, As you can see, density is in grams but the mass of mercury is in pounds. That means we need first, to convert pounds to grams to use density and obtain volume of mercury.

<em>Mass mercury in grams:</em>

1.50lb * (1kg / 2.20lb) = 0.682kg = 682g of mercury.

<em>Volume of mercury:</em>

682g Mercury * (1mL / 13.546g) =

Can you use volume to measure out a mole of a gas? Why or why not?
Rashid [163]

The volume of a gas is defined by the volume of its container.  

However, given the number of moles, and standard temperature and pressure, you can use the Ideal Gas Law to calculate the volume.
