Answers

Answer 1

The reaction that has been shown in the table above is a double replacement reaction, and each compound has the same set of ions. Option D

What is a reaction?

Another word that we can use for reaction is what we call a chemical change. We know that a chemical change is the kind of change that will lead to the formation of a new product. It is an irreversible process as we can not be able to get back the reactants again.

We should note that there are various types of reactions. In a single  replacement reaction, you would notice that there is only one substance that reacts and causes a change while in the double replacement reaction, the anions that are in the compounds that underwent the reaction would just exchange anion partners and we would have two ionic products.

What is neutralization reaction?

A neutralization reaction is a chemical reaction that occurs when an acid and a base react to form a salt and water. This type of reaction is exothermic, meaning that it releases energy in the form of heat. During a neutralization reaction, hydrogen ions from the acid are neutralized by the hydroxide ions from the base. The byproduct of this reaction is a salt and water. The salt produced depends on the acid and base used in the reaction, and the pH of the solution is neutralized to 7.0.

What process makes 2 ATP?

Anaerobic respiration results in the production of 2 ATP molecules.

What is anaerobic respiration?

Anaerobic respiration is the use of electron acceptors other than molecular oxygen in respiration. Despite the fact that oxygen is not the ultimate electron acceptor, the process employs a respiratory electron transport chain. When there is insufficient oxygen for some species to respire, they still require energy to survive. Due to a lack of oxygen, they respire in the absence of oxygen to create the energy they require, which is known as anaerobic respiration. While most aerobic respiration (with oxygen) occurs in the cell's mitochondria, anaerobic respiration (without oxygen) occurs in the cytoplasm.

an empty bottle has a volume of 2.0 L at room temperature 25 C. What will the new volume be if you put it in the freezer (-4C)

Answers

An empty bottle has volume of 2 L at room temperature 25°C . If we put it in the freezer (-4°C), the new volume will be 1.8L.

According to Charles' law, " the volume of a given amount of gas held at constant pressure is directly proportional to the kelvin temperature". The equation is represented as:

V₁/T₁ = V₂/T₂

This means, with increase in temperature, volume will also increase and vice versa.

According to question,

V₁ = 2.0 L

T₁ = 25°C = (25+273)K = 298 K

T₂ = -4°C = (-4 + 273)K = 269 K

Using Charles' law equation,

V₁/T₁ = V₂/T₂

⇒V₂ = V₁×T₂ / T₁

⇒V₂ = 2L × 269 K/298K

⇒V₂ = 1.8 L

Thus, the new volume when the bottle is put in a freezer (-4°C ) is 1.8 L

Coca-Cola is making a version of Coke that uses sucrose (C12H22O11) instead of high fructose corn syrup. If there are 39.24 grams of sucrose in a 12.0 fluid oz. can of this Coke, what is the molarity of sucrose in the Coke.

To find the molarity of sucrose in the Coke, we first need to find the number of moles of sucrose present in the can. We can use the mass of sucrose (39.24 g) and the molar mass of sucrose (342.3 g/mol) to find the number of moles of sucrose:

= (39.24 g) / (342.3 g/mol)

= 0.114 mol

Next, we need to find the volume of the can in liters. We can convert the volume in fluid oz. to liters using the conversion factor 1 fluid oz.

= 0.0295735 L:

= (12.0 fluid oz.) x (0.0295735 L/fluid oz.)

= 0.354882 L

Finally, we can use the formula for molarity (moles of solute / liters of solution) to find the molarity of sucrose in the Coke:

Law of conservation of atoms

According to the law of conservation of atoms or matter, atoms can neither be destroyed nor created during the course of chemical reactions. However, atoms can change forms during reactions.

Going by this law, it means the number of atoms of a particular element must remain constant before and after chemical reactions. Otherwise, we will say the chemical equation of such reactions are not balanced.

Thus, if there are 6 atoms of hydrogen on the products side of a reaction, 6 atoms of hydrogen must also be on the reactants side of the reaction.

What volume of 0.450 M Na3PO4 is required to precipitate all the lead(II) ions from 190.0 mL of 0.600 M Pb(NO3)2

Answers

We need 0.127 L of 0.450 M Na3PO4 to precipitate all the lead(II) ions from 190.0 mL of 0.600 M Pb(NO3)2.

How to determine the amount of Na3PO4 needed?

This is a precipitation reaction. To determine the amount of Na3PO4 needed to precipitate all the lead(II) ions, we need to find the number of moles of Pb(NO3)2 present in the solution.

First, we'll use the formula to convert the volume of the solution to liters:

190.0 mL * (1 L/1000 mL) = 0.19 L

Next, we'll use the molarity formula to find the number of moles of Pb(NO3)2 in the solution:

molarity (M) = moles of solute / liters of solution

moles of Pb(NO3)2 = 0.600 M * 0.19 L = 0.114 moles

Now we can use the balanced equation for the reaction to find how many moles of Na3PO4 are needed to react with all 0.114 moles of Pb(NO3)2

Pb(NO3)2 + 3Na3PO4 -> Pb3(PO4)2 + 6NaNO3

We can see that 2 moles of Pb(NO3)2 react with 3 moles of Na3PO4

So we need 0.114 moles/ 2 moles = 0.057 moles of Na3PO4

Finally we can use the molarity formula again to find the volume of 0.450 M Na3PO4 required

Molarity (M) = moles of solute / liters of solution

0.057 moles = 0.450 M * V

V = 0.057 moles / 0.450 M = 0.127 L

So we need 0.127 L of 0.450 M Na3PO4 to precipitate all the lead(II) ions from 190.0 mL of 0.600 M Pb(NO3)2

The biological evolution via natural selection theory was put out by British biologist Charles Darwin. Darwin believed that species change over time, give rise to new species, and descended from a single ancestor through the process of evolution. Charles Darwin's theory of evolution is known as natural selection. Animals with heritable qualities that aid in survival and reproduction will often generate more offspring than their contemporaries due to the limited resources in nature, increasing the frequency of such traits through subsequent generations.Populations change throughout time through natural selection, becoming increasingly adapted to their surroundings. Natural selection is reliant on the environment and necessitates the presence of heritable variation within a population.
