Answer:

AB + CD → AD + BC

Explanation:

This is a double displacement reaction. It is also known as precipitation reaction.

Answer: The double bonds in an aromatic ring are not fixed in position as in an alkene. The electrons are considered to be in conjugation and are delocalized around the ring.

Explanation:

Chemical compounds that have conjugated planar ring systems where there are delocalized pi-electron clouds are present in place of individual alternate and single bonds.

This means that electrons present in a double bond of alkene are in conjugation.

Therefore, we can conclude that the double bonds in an aromatic ring are not fixed in position as in an alkene. The electrons are considered to be in conjugation and are delocalized around the ring.

Answer:

C. About 50 more grams ammonia would be able to dissolve as the solution has become unsaturated

Explanation:

From the question, we have;

The mass of ammonia dissolved in water = 60 grams

The mass of the water solvent which dissolves the ammonia = 100 g

The temperature to which the ammonia water solution is raised = 90°C

Therefore, given that the solubility of a solute in a solvent increases with temperature, when the temperature is raised, we have, that the solution will more unsaturated and will be able to dissolve more ammonia, therefore, option 'C' is the most correct option that corresponds with the relationship of temperature and solubility

Nitrogen and hydrogen react to form ammonia and is a combination reaction. The grams of hydrogen used in the reaction with nitrogen to form ammonia is 2.0 grams.

Mass is the weight or the product of the volume and density of the substance. It can be calculated as, [tex]\rm volume \times density.[/tex]

Given,

Mass of nitrogen = 10.0 grams

Mass of ammonia = 12.0 grams

Mass of hydrogen = x gram

Solving for x:

[tex]\begin{aligned}\rm 10 + x &= 12\\\\\rm x &= 12.0 - 10.0\\\\&= 2.0 \;\rm grams\end{aligned}[/tex]

Therefore, 2.0 grams of hydrogen is required to react with 10.0 grams of nitrogen to produce 12.0 grams of ammonia.

Answer:

When a substance changes states, it requires energy when it goes to a higher energy state and releases energy when it goes to a lower energy state. Gas has a higher energy than liquid and liquid has a higher energy than solid. The three state changes from a lower energy to a higher energy are: solid to liquid: fusion. liquid to gas: vaporization

Answer:

Different compounds are formed.

Explanation:

Due to this switching of chemicals, the result of both beakers will be different because the chemicals react with the different solution in the beaker. The composition of both chemicals are different from one another which produces different compounds or products when they are mixed with the solution so we can say that this switching of chemicals will definitely affect the results of the experiment. The student will observe the formation of different compounds and different colour of the solution.

The statement which is true about the fuel cell is that It has an electrolyte that acts as a salt bridge.

A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) into electricity.

The fuel cell has an electrolyte that acts as a salt bridge.

As electrolytes are nothing but the salts which are present at the inner side of the U-Tube considered as Salt bridge present in fuel cell.

In this way, Fuel cell has electrolyte that acts as a salt bridge.

Answer:

2M

Explanation:

Molarity refers to the molar concentration of a solution. It can be calculated by using the formula as follows:

Molarity (M) = number of moles (n) ÷ volume (V)

Based on the information provided in this question, 2 moles of salt is dissolved to form 1 liter of solution. This means that n = 2mol, V = 1L

Molarity = n/V

Molarity = 2/1

Molarity = 2M

no. of mole = 88 ÷ ( 12 + 2(16) )

= 2 mol

mass of C = 2 × 12

= 24g ( A )

Answer:

Explanation:

I think you mean

2N2H4 + N2O4 ==> 3 N2 + 4H2O

The equation says that for Every mol of N2O4, you need 2 moles of N2H4.

1/2 = x/3,5       Multiply both sides by 3.5

3.5*1 / 2 = x

1.75 = x

Therefore you need 1.75 moles N2O4 are needed for 3.5 moles of N2H4

This is most easily solved using Gay-Lussac's Law, which relates temperature and pressure as follows:

[tex]P_{1} T_{1} =P_{2} T_{2}[/tex]

According to Gay-Lussac's law, the pressure of oxygen gas at 273 K is 1.34 atmospheres.

Gay- Lussac's law is defined as a gas law which states that the pressure which is exerted by the gas directly varies with its temperature and at a constant volume.The law was proposed by Joseph Gay-Lussac in the year 1808.

The pressure of the gas at constant volume reduces constantly as it is cooled till it undergoes condensation .Given by P₁/T₁=P₂/T₂ which on substitution gives P₂=3.5×273/713=1.34 atm.

Thus, the pressure of oxygen gas at 273 K is 1.34 atmospheres.
