A gas tank holds 20000 liters at 850 torr. If the temperature remains constant, what will the volume, in L, of the gas be at sta
nekit [7.7K]

Answer: 22368.4 Liters

Explanation:

Initial Volume of gas V1 = 20000 liters

Initial pressure of gas P1 = 850 torr

Final volume V2 = ?

Final (standard) pressure P2 = 760 torr

Apply the formula for Boyle's law:

P1V1 = P2V2

850torr x 20000L = 760torr x V2

V2 = (850torr x 20000L)/ 760torr

V2 = (17000000)/760torr

V2 = 22368.4L

Thus, the volume of the gas at standard pressure is 22368.4 Liters

How many moles of NaCl (s) can be formed from 32 moles of Cl2 (g) reacting with an excess of Na (s)?
blagie [28]

Answer:

64 moles

Explanation:

Let us begin by writing a balanced equation for the reaction. This is illustrated below:

2Na + Cl2 —> 2NaCl

From the equation above,

1 mole of Cl produced 2 moles of NaCl.

Therefore, 32 moles of Cl will produce = 32 x 2 = 64 moles of NaCl.

Therefore, 64 moles of NaCl are produced
