Fluorine gas and water vapor react to form hydrogen fluoride gas and oxygen. What volume of hydrogen fluoride would be produced
mafiozo [28]

Answer:

Hi, the question is incomplete. However, the question is about the calculation of volume of a product when the volume of one of the reactants is provided.

9.587 cm^3

Explanation:

The balanced equation for the chemical reaction is shown below:

2F_{2(g)} + 2H_{2}O_{(g)} ⇒4HF_{(g)} + O_{2(g)}

In the chemical reaction above, 2 moles of water produced 4 moles of hydrogen fluoride. If 4.8 cm^3 of water were consumed, we can calculated the volume of hydrogen fluoride that would be produced as follow:

Using STP, 1 mole of gas has a volume of 22.4 L

Thus, 4.8 cm^3 = 0.0048 L is equivalent to 2.14*10^-4

since 2 moles of water produced 4 moles of hydrogen fluoride, therefore, 2.14*10^-4 would produced 2*2.14*10^-4 = 4.28*10^-4 moles

we can convert the moles to L by multiplying with 22.4

volume of hydrogen fluoride = 4.28*10^-4 * 22.4 = 0.009587 L = 9.587 cm^3

19) What is the molarity of a KOH solution if 200 ml of the solution contains 0.6 moles KOH?
zloy xaker [14]

Answer: 3M

Explanation: Molarity : It is defined as the number of moles of solute present in one liter of solution.

Formula used :

Molarity=\frac{n\times 1000}{V_s}

where,

n = moles of solute KOH = 0.6 moles

V_s = volume of solution in ml= 200 ml

Now put all the given values in the formula of molarity, we get

Molarity=\frac{0.6moles\times 1000}{200ml}=3mole/L

Therefore, the molarity of solution will be 3M.

Mkey [24]

Answer:

Ethane

Explanation:

CH3-CH3 is an alkane by the name of ethane. In organic chemistry there is a systematic way of naming compounds according to the prefix (eth) and the suffix (ane.)

The prefixes vary according to the number of carbon atoms:

1 C = meth

2 C = eth

3 C = prop

4 C = but
