2. The temperature of CO2 gas at 99.3 mmHg was measured at 455 K. What will be the new temperature if the
pressure is adjusted to 202.6 mmHg? Assume constant volume.

928.33K

Explanation:

The following were obtained from the question:

P1 = 99.3 mmHg

T1 = 455 K

P2 = 202.6 mmHg

T2 =?

P1/T1 = P2 /T2

99.3/455 = 202.6/ T2

Cross multiply to express in linear form

99.3 x T2 = 455 x 202.6

Divide both side by 99. 3

T2 = (455 x 202.6) /99.3

T2 = 928.33K

The new temperature will be 928K

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
