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

How many moles of hydrogen are there, if there are 4 molecules of hydrogen?

Scorpion4ik [409]

Answer:

Explanation:

In this case, according to the Periodic table

there is 1g of hydrogen per mole. As we know that dihydrogen (H2) has two hydrogen atoms per molecule. So,there will be 2*1g hydrogen per mole=2g dihydrogen per mole.

If there is 2g dihydrogen per mole,and we have 4g,then we know that there is 2 mole dihydrogen in 4g.And for hydrogen there is 4 moles in 4g of hydrogen

How many isomers are there with the formula c3h4? include both structural and geometric isomers?

sleet_krkn [62]

There are three possible Isomers for Molecular Formula C₃H₄. Isomers are;

1) Propyne

2) Propa-1,2-diene

3) Cyclopropene

Structures of all three isomers are given below.

There are no geometrical isomers for given molecular formula because geometrical isomers are formed in compounds containing double bond with at least two bulky groups at both sp² hybridized carbons. In given isomers, propyne does not contain any double bond, Propa-1,2-diene is symmetrical in nature while cyclopropene is a 3-membered ring. And for cycloalkenes there must be other groups attached to ring other than Hydrogen atom, hence cyclopropene does not contain any other group, so it can not show geometrical isomerism.
