Explanation:

Carbonic acid, Sulfuric acid, and Nitric acid are the primary components of acid rain, all resulting from air pollution in the form of sulfur and nitrogen compounds respectively, reacting with water molecules in the atmosphere.

The primary components of acid rain are Carbonic acid, Sulfuric acid, Nitric acid. Acid rain is a result of air pollution, specifically sulfur and nitrogen compounds released from burning fossil fuels, which react with the water molecules in the atmosphere to form acids.

These acids then fall to the ground in the form of precipitation, giving us what we know as 'acid rain'. Sulfuric acid is formed from sulfur dioxide, while nitric acid forms from nitrogen oxides. Carbonic acid is formed by the reaction of carbon dioxide with water.

Answer: 43.5g of carbon dioxide it produce at 95% efficiency

Explanation:

[tex]2C_4H_{10}+13O_2\rightarrow 8CO_2+10H_2O[/tex]

To calculate the moles, we use the equation:

moles of butane =[tex]\frac{\text {given mass}}{\text {molar mass}}=\frac{15.0g}{58g/mol}=0.26moles[/tex]

According to stoichiometry:

2 moles of butane gives = 8 moles of carbon dioxide

Thus 0.26 moles of butane gives= [tex]\frac{8}{2}\times 0.26=1.04[/tex] moles of carbon dioxide

Mass of [tex]CO_2[/tex] produced=[tex]moles\times {\text {Molar mass}}=1.04\times 44=45.8g[/tex]

As yield of the reaction is 95%, the amount of [tex]CO_2[/tex] produced =[tex]\frac{95}{100}\times 45.8=43.5g[/tex]

Thus 43.5g of carbon dioxide it produce at 95% efficiency

To determine the molecular mass of the acid used in the esterification reaction, additional information about the alcohol involved or the identity of the acid is needed. Without these details, an accurate determination of the acid's molecular mass is impossible.

To find the molecular mass of the acid used in the esterification reaction to create a fat with the molecular mass of 386 g/mol, further information is needed. This would typically include the molecular mass of the alcohol also involved in the reaction, or the identity of the acid or alcohol. The molecular mass of the acid or the alcohol could be deduced from the formula of the reaction itself:

Fat = Acid + Alcohol - Water

However, without knowing the molecular mass of the alcohol or the identity of the acid or alcohol, we cannot accurately determine the molecular mass of the acid alone.

Answer:

The number of moles of potassium hydroxide, KOH required to make 4 moles of K₂SO₄ is 8 moles of KOH

Explanation:

2KOH + H₂SO₄ → K₂SO₄ + 2H₂O

From the above reaction, we have 2 moles of KOH combining with 1 mole of H₂SO₄ to produce 1 mole of K₂SO₄  and 2 moles of H₂O.

Therefore the number of moles of potassium hydroxide that will be needed to make 4 moles of K₂SO₄ is;

8KOH + 4H₂SO₄ → 4K₂SO₄ + 8H₂O

8 moles of KOH is required to make 4 moles of K₂SO₄.

Final answer:

To make 4 moles of K2SO4, 8 moles of KOH are needed.

Explanation:

To find the number of moles of potassium hydroxide (KOH) needed to make 4 moles of K2SO4, we need to use the balanced chemical equation:

2KOH + H2SO4 → K2SO4 + 2H2O

From the equation, we can see that 2 moles of KOH react with 1 mole of H2SO4 to form 1 mole of K2SO4. Therefore, the mole ratio is 2:1.

Since we want to make 4 moles of K2SO4, we can set up the following proportion:

(2 moles KOH) / (1 mole H2SO4) = (x moles KOH) / (4 moles K2SO4)

Cross multiplying gives:

2 moles KOH = 4 moles K2SO4 * 2 moles KOH / 1 mole H2SO4 = 8 moles KOH

Therefore, 8 moles of KOH are needed to make 4 moles of K2SO4.

O:                     3                            1

Mg:                         1                 1

Let's guess and make the number of oxygens equal on both sides.

O:                      3                           3       EQUAL

Mg:                          1                   3

See what we did there? We multiplied the MgO on the products side by 3 so we can have 3 oxygens. Now let's multiply the Mg on the reactants by three so Mg AND O can be equal.

                Cr2O3+3Mg -->Cr + 3 MgO

Cr:              2                      1

Mg:                         3                        3          EQUAL

Finally, we just need to multiply the loner Cr in the products side by two to make it equal for all elements.

D = 28.2g

Explanation:

Initial temperature of metal (T1) = 155°C

Initial Temperature of calorimeter (T2) = 18.7°C

Final temperature of solution (T3) = 26.4°C

Specific heat capacity of water (C2) = 4.184J/g°C

Specific heat capacity of metal (C1) = 0.444J/g°C

Volume of water = 50.0mL

Assuming no heat loss

Heat energy lost by metal = heat energy gain by water + calorimeter

Heat energy (Q) = MC∇T

M = mass

C = specific heat capacity

∇T = change in temperature

Mass of metal = M1

Mass of water = M2

Density = mass / volume

Mass = density * volume

Density of water = 1g/mL

Mass(M2) = 1 * 50

Mass = 50g

Heat loss by the metal = heat gain by water + calorimeter

M1C1(T1 - T3) = M2C2(T3 - T2)

M1 * 0.444 * (155 - 26.4) = 50 * 4.184 * (26.4 - 18.7)

0.444M1 * 128.6 = 209.2 * 7.7

57.0984M1 = 1610.84

M1 = 1610.84 / 57.0984

M1 = 28.21g

The mass of the metal is 28.21g

Option C, (Actual yield ÷ percent yield) × 100

Explanation:

Theoretical yield is defined as the total amount of product formed for given reactants in a chemical reaction.  It is an ideal case which assumes no exceptions or wastage.

The mathematical relation between the actual yield, percent yield and theoretical yield is as follows -

[tex]P.Y. = \frac{M_{A.Y.}}{M_{T.Y.}} * 100[/tex]

Where

P.Y. represents the percent yield a

M A.Y. represents the mass obtained from actual yield

M T.Y. represents the mass obtained from theoretical yield

Hence, if we rearrange the formula, we get -

[tex]M_{T.Y.} = \frac{M_{A.Y.}}{P.Y.} * 100[/tex]

Answer:

1) Adding more NH₃

2) Raising the temperature of the reaction

Explanation:

To answer the question, we are to note that the reaction is a reversible reaction, hence to shift the equilibrium to the left we would alter the equilibrium conditions as follows;

1) Adding more of the product NH₃ to the reaction at equilibrium

Increasing the quantity of products will force the concentration of the reactant product combination at equilibrium to readjust forming more of the reactant, because, for example, at equilibrium we have one mole of N₂ combining with 3 moles of H₂ forming 2 moles of NH₃. If the NH₃ is increased to 4 moles then there will be more H₂ and N₂ formed to regain equilibrium

2) Increasing the reaction temperature

It is also observed that the reaction produces energy, that the the energy of the product is less than those of the reactant. Therefore, to shift the equilibrium to the left, that is towards the reactants, we have to increase the temperature of the reaction so that there will be enough energy for the formation of the higher energy reactants.

2)A solution that is neither acidic nor basic is neutral and has a pH of 7. The pH scale, which ranges from 0 to 14, indicates how acidic or basic a substance is. A substance that has a pH below 7 is and acid and a substance with a pH above 7 is a base.

3)Self raising flour rises due to the baking powder inside.

Self raising flour is different from normal flour as it has baking powder mixed inside already. Baking powder is usually made up of a chemical called sodium carbonate, when mixed with water this will releases the gas carbon dioxide. So when you mix a cake together and pour it into a tin, the heat plus the water in the mixture will cause the baking powder to release small amounts of carbon dioxide which produces bubbles. These bubbles try to rise up and so the mixture starts to rise with all the tiny bubbles. The reason the air does not escape is because the heat from the oven is making the cake solid. Once is it solid the carbon dioxide slowly leaves the bread or cake, so don’t worry you’re not eating loads of carbon dioxide
