Consider a balloon with volume V. It contains n moles of gas and has an internal pressure of P. The temperature of the gas is T.

Maksim231197 [3]

Answer:

V₂ = 0.6 V.

Explanation:

We can use the general law of ideal gas: PV = nRT.

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

If n is constant, and have different values of P, V and T:

(P₁V₁T₂) = (P₂V₂T₁).

V₁ = V, P₁ = P, T₁ = T.

V₂ = ??? V, P₂ = 1.25 P, T₂ = 0.75 T.

∴ V₂ = (P₁V₁T₂)/(P₂T₁) = (P)(V)(0.75 T)/(1.25 P)(T) = 0.6 V.

A chemist mixes 71.1 g of carbon tetrachloride with 65.4 g of isopropenylbenzene and 4.02 g of 2-ethyltoluene. Calculate the per

-Dominant- [34]

Answer:

% Carbon tetrachloride = 50.6 %

% isopropenylbenzene = 46.5 %

% 2-ethyltoluene = 2.9%

Explanation:

Step 1: Data given

A mixture contains:

71.1 grams of Carbon tetrachloride (CCl4)

65.4 grams of isopropenylbenzene (C9H10)

4.02 grams of 2-ethyltoluene (C9H12)

Step 2: Calculate total mass

Total mass = mass CCl4 + mass C9H10 + mass C9H12

Totam mass = 71.1g + 65.4g + 4.02g

Total mass = 140.52 grams

Step 3: Calculate % of each component:

% component = (mass component/ total mass) *100%

% Carbon tetrachloride = (71.1 / 140.52) *100 %

% Carbon tetrachloride = 50.6 %

% isopropenylbenzene = (65.4 / 140.52) *100%

% isopropenylbenzene = 46.5 %

% 2-ethyltoluene = (4.02/140.52) *100%

% 2-ethyltoluene = 2.9%

50.6% + 46.5% + 2.9% = 100%

Carbon burns in the presence of oxygen to give carbon dioxide. Which chemical equation describes this reaction?

Phoenix [80]

Answer: Option (B) is the correct answer.

Explanation:

It is known that for writing a chemical reaction equation, reactants are written on left hand side whereas products are written on right hand side.

And in between reactants and products a forward arrow is placed pointing towards the products.

Therefore, the reaction for carbon burns in the presence of oxygen to give carbon dioxide will be written as follows.

$Carbon + Oxygen \rightarrow Carbon dioxide$

Here, carbon and oxygen atoms are the reactants whereas carbon dioxide is the product.
