Which of the following is true about this type of chemical reaction?

It is a single replacement reaction, and all four compounds are different.

It is a double replacement reaction, and all four compounds are different.

It is a single replacement reaction, and each compound has the same set of ions.

It is a double replacement reaction, and each compound has the same set of ions.

Answers

Answer 1

Answer: The given type of chemical reaction is a double replacement reaction, and each compound has the same set of ions.

Explanation:

When two different compounds chemically react with each other and their ions get exchanged with each other then it leads to the formation of two new compounds. This type of reaction is called double displacement reaction.

For example, [tex]KBr + AgNO_{3} \rightarrow KNO_{3} + AgBr(\downarrow)[/tex]

Here, both KBr and [tex]AgNO_{3}[/tex] are ionic compounds that leads to the formation of two new ionic compounds which are [tex]KNO_{3}[/tex] and AgBr.

Thus, we can conclude that the given type of chemical reaction is a double replacement reaction, and each compound has the same set of ions.

Which statement about the mass of an electron is correct? A The mass of an electron is equal to the mass of the proton. B The mass of an electron is less than the mass of the proton. с The mass of an electron is equal to the mass of a neutron. D The mass of an electron is greater than the mass of a neutron.​

Answers

Answer:

B

Explanation:

because mass of an electron is 1/2000.

The statement about the mass of an electron which is correct is: B. The mass of an electron is less than the mass of the proton.

An atom refers to a smallest, indivisible unit that comprises the matter that forms all chemical elements. Therefore, atoms are typically considered as the fundamental building blocks of matter which determines the structure of a chemical element.

Basically, an atom consists of three (3) distinct particles and these include;  

Protons. Neutrons. Electrons.

Electrons are the subatomic particles of a chemical element that are negatively charged with a magnitude of -1.

On the other hand, protons can be defined as the subatomic particles of a chemical element that are positively charged.

All of these subatomic particles of a chemical element has a mass. However, the mass of an electron is significantly less than the mass of proton, as a result of its extremely small size.

In conclusion, the mass of an electron is approximately 2000 times smaller than that of a proton and as such contributes almost nothing to the total mass of an atom.

Atoms are attracted to each other because____

A) electrons are attracted to protons because they have opposite charges
B) magnets pull them together
C) the protons are attracted to each other because they have the same charge
D) they have some energy

SOMEONE PLEASE HELP:/!

Answers

Answer:

A

Explanation:

Opposite charges attract therefore the electrons of one atom would be attracted by the nucleus (which contains protons). This heavily relies on a property called electronegativity. Which deals with the level of attraction a nucleus (the protons in the nucleus) have for electrons of other atoms.

Explanation:

Let's consider the following oxidation half-reaction that takes place in basic aqueous solution.

Mn(s) ⇒ MnO₄⁻(aq)

First, we will perform the mass balance. We will add 4 H₂O to the products side and 8 OH⁻ to the reactants side.

8 OH⁻(aq) + Mn(s) ⇒ MnO₄⁻(aq) + 4 H₂O(l)

Finally, we will perform the charge balance by adding 7 electrons to the products side.

8 OH⁻(aq) + Mn(s) ⇒ MnO₄⁻(aq) + 4 H₂O(l) + 7 e⁻

Cholesterol has a formula of C27H46O. What is the mass in grams of one molecule of cholesterol?

Answers

The molar mass of cholesterol = 386.654 g/mol = 387 g/mole

3.2 mg cholesterol x 1 g/1000 mg x 1 mole/387 g x 6.02x1023 molecules/mole = 5.0x1018  molecules.

The mass in grams of one molecule of cholesterol, C27H46O is 6.43×10⁻²² g

Avogadro's hypothesis

6.02×10²³ molecules = 1 mole of Cholesterol

But,

1 mole of Cholesterol = 387 g

Thus,

6.02×10²³ molecules = 387 g mole of Cholesterol

How to determine the mass of one molecule

6.02×10²³ molecules = 387 g mole of Cholesterol

1 molecule = 387 / 6.02×10²³

1 molecule = 6.43×10⁻²² g of Cholesterol

Thus, the mass of 1 molecule of cholesterol is 6.43×10⁻²² g

Which is an effect of burning fossil fuels?
A. Alkanes are converted to alkenes.
B. Natural gas forms underground.
C. Pollution is released into the atmosphere.
D. Oxygen gas is given off.

Answers

Answer:

C

Explanation:

When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air.

Burning fossil fuels, such as coal, oil, and natural gas, releases various pollutants into the atmosphere. The correct answer is C. Pollution is released into the atmosphere.

Burning fossil fuels involves the combustion of carbon-based compounds, such as hydrocarbons, present in these fuels. When these fuels are burned, they react with oxygen in the air, releasing energy in the form of heat and producing combustion byproducts.

One significant effect of burning fossil fuels is the release of pollution into the atmosphere. Carbon dioxide (CO₂) is the primary greenhouse gas emitted during the combustion process. It contributes to the greenhouse effect, trapping heat in the Earth's atmosphere and leading to global warming and climate change. These pollutants include carbon dioxide (CO₂), sulfur dioxide (SO₂), nitrogen oxides (NOx), particulate matter, and other harmful substances. These pollutants contribute to air pollution and can have negative effects on human health, ecosystem health, and climate change.

Hence, the correct option is option c.

2P(s) + X(g) ↔ P2X(g) at 20°C, Keq= 4.0 Initially, 2.0 moles of P(s) and 1.0 mole of X(g) are put into a 1.0L flask and allowed to react until they reach equilibrium. The molarity of P2X (g) present at equilibrium is: a. 1.0 M b. 0.8 M c. 0.4 M d. 0.1 M

Answers

Answer:

b. 0.8 M

Explanation:

Based on the reaction, Keq is defined as:

Keq = 4.0 = [P2X] / [X]

As P is a pure solid, its concentration is not taken into account

The initial concentration of X is 1.0mol/L = 1M, the equilibrium concentrations are:

[X] = 1M - X

[P2X] = X

Where X is the reaction coordinate

Replacing:

4.0 = X / 1-X

4.0 - 4.0X = X

4.0 = 5.0X

0.8M = X = [P2X]

Right answer is:

b. 0.8 M

distilling ethanol from a wine to determine the percentage of alcohol in a wine uses what type of property

physical property
bonding property
homeowner's property​

Answers

Answer:

Bonding property

Explanation:

Distillation deals with boiling solutions. Therefore the boiling point has a major part to play. Boiling point of a substance deals with the type of bonds present. For example water has hydrogen bonding which is a weak intermolecular force therefore the boiling point of water isn't that high. If we were to focus on an ionic compounds the boiling point would be higher because ionic compounds have ionic bonding which are stronger bonds which therefore requires more energy to break those bonds therefore a higher boiling point.

In this case for the ethanol to distill the property it's focusses on is the bonds. The strength of the bonds really.
