Answer:

4.58g of CO₂ could be produced

Explanation:

Based on the reaction:

C₂H₄(g) + 3O₂(g) → 2CO₂(g) + 2H₂O(g)

1 mole of C₂H₄ reacts with 3 moles of oxygen to produce 2 moles of CO₂

To solve this question we must find the moles of each reactant in order to find limiting reactant. With limiting reactant we can find the moles -And the mass- of CO₂ produced:

Moles C₂H₄ -Molar mass: 28.05g/mol-

2.0g * (1mol / 28.05g) = 0.0713moles

Moles O₂ -Molar mass: 32g/mol-

5.0g * (1mol / 32g) = 0.156moles

For a complete reaction of 0.0713 moles of C2H4 are required:

0.0713 moles C₂H₄ * (3 moles O₂ / 1 mol C₂H₄) = 0.214 moles of O₂

As there are just 0.156 moles, O₂ is limiting reactant.

The moles of CO₂ produced are:

0.156 moles O₂ * (2mol CO₂ / 3mol O₂) = 0.104 moles CO₂

The mass is -Molar mass CO₂: 44.01g/mol-

0.104 moles CO₂ * (44.01g / mol) =

Explanation:

The molarity of a solution with 55 grams of CaCl2 dissolved in 0.78 L is 0.64M. Details about molarity is found below.

The molarity of a solution can be calculated by dividing the number of moles of the substance by its volume.

However, the number of moles of a substance must first be calculated using the following expression:

no of moles = 55g ÷ 111g/mol

no of moles = 0.49mol

Molarity of CaCl2 solution = 0.49mol ÷ 0.78L

Molarity of CaCl2 solution = 0.64M

Therefore, the molarity of a solution with 55 grams of CaCl2 dissolved in 0.78 L is 0.64M.

Explanation:

37Ca and 53Fe have the same decay mode.

Three of the most common types of decay are alpha decay (α-decay), beta decay (β-decay), and gamma decay (γ-decay), all of which involve emitting one or more particles.

The most likely mode of decay for a neutron-rich nucleus is one that converts a neutron into a proton. Every neutron-rich radioactive isotope with an atomic number smaller than 83 decays by electron emission. C, 32P, and 35S, for example, are all neutron-rich nuclei that decay by the emission of an electron.

Explanation:

2.: (i) A hissing sound is observed.

1.ii) The mixture starts boiling and lime water is obtained.

Answer:

Pressure increases to 1.16 atm if the temperature changes to 317 K.

Explanation:

The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C (or 273 K) are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

On the other hand, Gay Lussac's law indicates that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. This law mathematically indicates that the quotient between pressure and temperature is constant:

[tex]\frac{P}{T}=k[/tex]

Studying an initial state 1 and a final state 2 is fulfilled:

[tex]\frac{P1}{T1}=\frac{P2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{1 atm}{273 K} =\frac{P2}{317 K}[/tex]

Solving:

[tex]P2=317 K*\frac{1 atm}{273 K}[/tex]

P2= 1.16 atm

Pressure increases to 1.16 atm if the temperature changes to 317 K.

Answer:

8. 171074.8 mL

9. 3475 mL.

Explanation:

8. Determination of the volume of the diluted solution.

Initial Molarity (M₁) = 14 M

Initial volume (V₁) = 523 mL

Final Molarity (M₂) = 0.0428 M

Final volume (V₂) =?

Using the dilution formula, we can obtain the volume of the diluted solution as follow:

M₁V₁ = M₂V₂

14 × 523 = 0.0428 × V₂

7322 = 0.0428 × V₂

Divide both side by 0.0428

V₂ = 7322 / 0.0428

V₂ = 171074.8 mL

Therefore, the volume of the diluted solution is 171074.8 mL

9. Determination of the volume of water added.

We'll begin by calculating the final volume of the solution. This can be obtained as follow:

Initial Molarity (M₁) = 3.2 M

Initial volume (V₁) = 973 mL

Final Molarity (M₂) = 0.7 M

Final volume (V₂) =?

M₁V₁ = M₂V₂

3.2 × 973 = 0.7 × V₂

3113.6 = 0.7 × V₂

Divide both side by 0.7

V₂ = 3113.6 / 0.7

V₂ = 4448 mL

Thus, the final volume of the solution is 4448 mL

Finally, we shall determine the volume of water added. This can be obtained as follow:

Initial volume (V₁) = 973 mL

Final volume (V₂) = 4448 mL

Volume of water added =?

Volume of water added = V₂ – V₁

Volume of water added = 4448 – 973

Volume of water added = 3475 mL

The other relationship that will have a similar graph is volume versus temperature, because they are also directly proportional according to Charles's Law.

Charles's Law is a gas law that states that the volume of a fixed mass of gas at a constant pressure is directly proportional to its absolute temperature.

This means that as the temperature of a gas increases, the volume of the gas will also increase proportionally, and as the temperature of a gas decreases, the volume of the gas will decrease proportionally.

Therefore, if a graph of gas pressure versus the number of particles in a container is a straight line, a graph of volume versus temperature will have a similar shape and be directly proportional, because they are both affected by changes in temperature.

Answer: The compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.

Explanation:

If electronegativity difference between two atoms is less than 0.4 then bond formed is a pure covalent bond.

If electronegativity difference between two atoms is between 0.4 to 1.8 then bond formed is a polar covalent bond.

If electronegativity difference between two atoms is greater than 1.8 then bond formed is an ionic bond.

The electronegativity value of a nitrogen atom is 3.04. Hence, the electronegativity difference of [tex]N_{2}[/tex] molecule is as follows.

[tex]Electronegativity difference = electronegativity value of N - electronegativity value of N\\= 3.04 - 3.04\\= 0[/tex]As the electronegativity difference is 0 which is less than 0.4.

Hence, we can conclude that the compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.

Answer:

5.12 m³

Explanation:

Using the combined gas law formula as follows:

P1V1/T1 = P2V2/T2

Where;

P1 = initial pressure (atm)

P2 = final pressure (atm)

V1 = initial volume (m³)

V2 = final volume (m³)

T1 = initial temperature (K)

T2 = final temperature (K)

According to this question;

V1 = 5.0 m³

V2 = ?

P1 = 0.84 atm

P2 = 0.89 atm

T1 = 298 K

T2 = 323 K

Using

P1V1/T1 = P2V2/T2

0.84 × 5/298 = 0.89 × V2/323

4.2/298 = 0.89V2/323

Cross multiply

4.2 × 323 = 298 × 0.89V2

1356.6 = 265.22V2

V2 = 1356.6 ÷ 265.22

V2 = 5.12 m³

Answer:

the volume is 18.45 L

Explanation:

The computation of the volume when the temperature is increased to 60.0 K is shown below:

Since the gas occupied 12.3 L at a temperature of 40.0 k

And, the volume when the new temperature is 60.0 k

So, the volume is

= 60.0 k × 12.3 L ÷ 40.0 k

= 18.45 L

hence,  the volume is 18.45 L

Water beneath the earth surface is called ground water. The storage of ground water is a very important in all areas to sustain our need for water and it must be maintained pure without the presence of overdose of heavy metals and other impurities.

Reduction in the level of ground water storage is a serious issue that might leads to a scenario where the drinking water is not sufficient. The uncontrolled use of pump water by factories,  industries and farms results in the drop of ground water level.

The nearby farms might pumping water from sources uncontrollably in the area. That is the main reason of dropping in ground water level. Hence, option B is correct.
