What will happen if 2.3 L of nitrogen gas is added to a 5 L flask that contains a mixture of carbon monoxide, oxygen, and carbon

stiks02 [169]

Answer:

The equilibrium will remain at the same conditions because there is no effect and difference in the partial pressure which in turn affect the equilibrium state.

Explanation:

As Nitrogen is an inert gas therefore it will not react with either the reactants or products.
Also as the addition is being made by maintaining the volume of flask as constant, thus there will be no difference in the partial pressure of the individual components of the mixture by addition of the Nitrogen gas.
An increase in pressure is observed but the effect is not aiding or retreating the equilibrium conditions

Calculate the molarity of the solution if 80.0 g of Kool-Aid is dissolved in 1.0<br> L of solution.

Serga [27]

Answer:

.234 M

Explanation:

Molarity, or concentration, of a substance is simply found by dividing the amount of that substance in moles by its volume. Here, we are given the mass (in grams) of Kool-Aid, so we need to convert that to moles. To do this, we simply need the chemical formula of Kool-Aid, which I have found to be C12H22O11. The molar mass of C12H22O11, using the periodic table, is 342.296 g. Next, take this molar mass and divide the given mass of Kool-Aid by it. You then get about .234 mol Kool-Aid.

Lastly, divide this by the volume of 1.0 L. You get .234 M as your final molarity.

A) What volume of butane (C 4 H 10 ) can be produced at STP, from the reaction of 13.45 g of carbon with 17.65 L of hydrogen gas

UNO [17]

From the stoichiometry of the reaction, carbon is in excess and 5.856 g s left over.

<h3>What is the volume of butane produced?</h3>

The reaction can be written as; 4C(s) + 5H2(g) -----> C4H10(g)

Number of moles of C = 13.45 g/1 2g/mol = 1.12 moles

If 1 mole of hydrogen occupies 22.4 L

x moles of hydrogen occupies 17.65 L

x = 0.79 moles

Now;

4 moles of carbon reacts with 5 moles of hydrogen

1.12 moles of carbon reacts with 1.12 moles * 5 moles/4 moles

= 1.4 moles of hydrogen

Hence hydrogen is the limiting reactant here and carbon is in excess.

If 4 moles of carbon reacts with 5 moles of hydrogen

x moles of carbon reacts with 0.79 moles of hydrogen

x = 0.632 moles

Number of moles of carbon unreacted = 1.12 moles - 0.632 moles

= 0.488 moles

Mass of carbon unreacted = 0.488 moles * 12 g/mol

= 5.856 g

Volume of butane produced is obtained from;

5 moles of hydrogen produces 1 mole of butane

0.79 moles of hydrogen produces 0.79 moles * 1 mole/ 5 moles

= 0.158 moles

1 mole of butane occupies 22.4 L

0.158 moles of butane occupies 0.158 moles * 22.4 L/ 1 mole

= 3.53 L
