What is the pressure exerted by a 0.500 mol sample of nitrogen in a 10.0 L container at 20°C?

Enter your answer in the provided box.

Answer:

V₂ = 50.93 L

Explanation:

Initial volume, $V_1=43.1\ L$

Initial temperature, $T_1=24^{\circ} C=24+273=297\ K$

Final temperature, $T_2=78^{\circ} C=78+273=351\ K$

We need to find the final volume of the gas. The relation between the volume and the temperature is given by :

$\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}\\\\V_2=\dfrac{V_1T_2}{T_1}\\\\V_2=\dfrac{43.1\times 351}{297}\\\\V_2=50.93\ L$

So, the final volume of the gas is 50.93 L.

The cis and trans geometric isomers of a compound have different chemical and physical properties. Draw the structure of the geo

frutty [35]

Answer: The structure of the geometrical isomers are attached below.

Explanation:

Cis- and Trans- isomers are the geometrical isomers which have same chemical formula but different structural formula

According to CIP rule, the groups on the doubly bonded carbon atoms are given priorities based on the the atomic masses of first connected atom.

If the highest priority groups are on the same side, it is known as cis-form and if the highest priority groups are on opposite side, it is known as trans-form.

We are given a chemical compound, which is 2-pentene.

In this the highest priority groups are methyl and ethyl groups.

When the groups are on the same side, it forms cis-form and when the groups are on the opposite side, it forms trans-form

The structure of the geometrical isomers are attached below.

Debora [2.8K]

The complete balanced chemical equation is:
4 NH3 (g) + 5 O2 (g) → 4 NO (g) + 6 H2O (g)

In statement form: 4mol NH3 reacts with 5 mol O2 to produce 6 mol H2O

First let us find for the limiting reactant:
>molar mass NH3 = 17 g/mol
moles NH3 = 54/17 = 3.18 mol NH3
This will react with 3.18*5/4 = 3.97 mol O2

>molar mass O2 = 32g/mol
moles O2 = 54/32 = 1.69 mol O2
We have insufficient O2 therefore this is the limiting reactant

From the balanced equation:
For every 5.0 mol O2, we get 6.0 mol H2O, therefore

moles H2O formed = 1.69 mol O2 * 6/5 = 2.025 mol
Molar mass H2O = 18g/mol
mass H2O formed = 2.025*18 = 36.45 grams H2O produced

A substance made of two or more elements chemically combined in a set ratio, or proportion, is called a ___.

snow_lady [41]

Hey there!

The correct answer to your question is a compound.

A substance of two or more elements chemically combined in a set ratio, or proportion, is called a compound.
This is because compounds are made of two or more elements. Table salt is an example of a compound because it is made up of the elements chlorine and sodium.

Hope this helps you.
Have a great day!
