<u>Answer:</u> The volume of the gas is 178.76 L
<u>Explanation:</u>
The ideal gas equation is given as:
.......(1)
where
P = pressure of the gas = 675 torr
V = volume of gas = ?
n = number of moles of gas = 6.45 moles
R = Gas constant = 62.36 L.torr/mol.K
T = temperature of the gas = ![27^oC=[27+273]K=300K](https://tex.z-dn.net/?f=27%5EoC%3D%5B27%2B273%5DK%3D300K)
Putting values in equation 1, we get:
Hence, the volume of the gas is 178.76 L
Answer:
686.43363984 is the answer when 7.8 moles is converted.
Answer:
Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
Explanation:
The thing that two changes have in common that snails growing shells and rust forming on a bicycle frame is option D. Both are caused by cooling.
<h3>How come snails develop shells?</h3>
Calcium carbonate is said to be the material that makes up the shell. The snail's shell expands as it grows to accommodate its growing body. Snails and slugs are also members of the mollusc family of creatures.
Therefore, note that air that has been mixed with the metal can make rust to develop. and as such, option D. Both are caused by cooling. is correct.

C. Both are chemical changes.
D. Both are caused by cooling
Answer:
solution given:
Explanation:
4Fe +3O2------------>2Fe2O3
4mole. 3mole. 2 mole
224g. 96g. 320g
we have
224 g of fe needed to react completely with 96 g of O2
500g of fe needed to react completely with
96 ×500/224=214.3g of O2
214.3g of O2 is a required answer.
