Why is carbon dioxide nonpolar?

1 answer:

8 0

CO2 is a linear molecule and the Oxygen (O) atoms on each end are symmetrical. Polarity results from an unequal sharing of valence electrons. Because of this symmetry there is no region of unequal sharing and CO2 is anonpolar molecule

In terms of shape and volume, how can a gas be defined ?

Gnoma [55]

Particles in a gas are far apart compared to a solid or liquid, allowing it not to have a definitive shape or volume. This also means that gases can fill any container and be easily compressed.

Given the following masses, calculate the mass of water lost & determine the percent hydration.

lisabon 2012 [21]

You are given the mass of hydrate which is 10.24g and the mass of anhydrate which is 8.74g. Hydrate means that it contains water and anhydrate means the substance has lost water during the process. So you just subtract them, 10.24g – 8.74g = 1.5g of water is lost. Percent hydration is equal to one subtracted to the mass of anhydrate divided by the mass of hydrate multiplied by 100. So we have, [1-(8.74g/10.24g)] *100 = 14.65% or 15%. Your answers are correct.

Complete Question

4. A piece of metal weighing 0.0713 g was placed in a eudiometer containing dilute aqueous HCl. After the metal fully dissolved, 23.5 mL of hydrogen gas was collected by displace-ment of water and a 400 mm column of water was observed. The water temperature was 258C and the barometric pressure was 758.8 mm Hg (torr). Refer to the Introduction and data sheet to solve the following problems.

a) What is the vapor pressure of the water vapor in the column? (Consult Appendix E.)

b) What is the pressure of the water column expressed in mm Hg (torr)? The density of mercury is 13.6 g/mL.

c) Calculate the pressure of the hydrogen gas above the water in the column.

d) Calculate the volume occupied by the hydrogen gas at STP.

Answer:

a) $25\textdegree C=23.8 torrs$
