A 6.35 l sample of carbon monoxide is collected at 55.0◦c and 0.892 atm. What volume will the gas occupy at 1.05 atm and 59.0◦c?

Sonja [21]

Answer : The final volume of gas will be, 5.46 L

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 0.892 atm

$P_2$ = final pressure of gas = 1.05 atm

$V_1$ = initial volume of gas = 6.35 L

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = $55.0^oC=273+55.0=328K$

$T_2$ = final temperature of gas = $59.0^oC=273+59.0=332K$

Now put all the given values in the above equation, we get:

$\frac{0.892atm\times 6.35L}{328K}=\frac{1.05atm\times V_2}{332K}$

$V_2=5.46L$

Thus, the final volume of gas will be, 5.46 L

If 9.0g of water contain 1.0 g of hydrogen what mass of oxygen is contained in 36 g of water

Mazyrski [523]

9/1 ratio so 9:1=36:x
X is your hydrogen in the 36g sample. To find the mass of Oxygen you subtract the mass of hydrogen from the total.
4 grams H
36-4=32 g h2o

A substance is composed of only one kind of atom and can't be separated into simpler substances or converted into another substa

Svetach [21]

The substance most likely is an inert element because it is only composed of one kind of atom and cant be separated further. Also, it cannot be converted to another type of substance. An inert material doesn't react to any substance. Examples are Neon and Krypton.
