The answer to this question is <span>b) hydrogen chloride (HCl) is added to the system. This is the only acid/base on the list. Only acids and bases have the potential to directly change pH as they contribute hydronium and hydroxide ions. Glucose, sodium chloride, and sodium bromide do not affect pH in the first place.</span>

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?
Anna11 [10]

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.

What is the number of moles in 432g Ba(NO3)2
777dan777 [17]

First there is a need to calculate the molar mass of Ba(NO₃)₂:

137.3 + 2 (14.0) + 6 (16) = 261.3 grams/mole

The molar mass, denoted by M in chemistry refers to a physical characteristic illustrated as the mass of a given component divided by the amount of the component. The molar masses are always denoted in grams/mole.

After finding the molar mass, the number of moles can be identified as:

432 grams / 261.3 g/mol = 1.65 moles of Ba(NO₃)₂.
