Acylinder fitted with a movable piston and filled with a gas has a volume of 16.44 liters at 22.4°c when the applied pressure is 772.2 torr.
the temperature of the oil bath surrounding the piston was increased to 184.4°c, and the pressure on the piston was changed. careful measurement now gave a value of 39.03 liters for the new volume.

what is the final pressure in the cylinder, expressed in torr?

a) 494.0 torr

b) 503.6 torr

c) 1184 torr

d) 1207 torr

e) 6295 torr

with explanation .

b) 503.6 torr

Explanation:

Given data

We can find the final pressure applying the combined gas law.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

b. examine and describe cells
