If a liquid is sealed in a container and kept at constant temperature, how does its vapor pressure change over time?
a. It continues to steadily increase.
b. It increases at first, then remains constant.
c. It increases at first, then decreases.
d. It continues to steadily decrease.
Answer
The vapor pressure of the container sealed with liquid will increase first and then it will remain constant when kept at constant temperature.
Explanation
The vapor pressure in the container containing liquid will increase at first then remain constant. This trend of vapor pressure follows because pressure and vapor is generated by heat. Since the heat container is constant as it is kept at a constant temperature the pressure changes accordingly to the temperature and will remain there unless it is released.
Hence, the vapor pressure of the container containing liquid which is kept at constant temperature increases and remain constant.

which of the following statements about the nucleus of a typical atom is false? group of answer choices the nucleus contains both protons and neutrons the nucleus repels the electrons which move around it the nucleus contains most of the mass of the atom the nucleus has an overall positive charge
False, Protons and neutrons are both present in the nucleus.
What is the nuclear force?
One of the four fundamental forces of nature, along with gravitational and electromagnetic forces, is the nuclear force. In fact, they are also referred to as strong forces since they are 10 million times more powerful than chemical binding forces. A force known as the nuclear force interacts with the protons and neutrons of atoms. The force that holds protons and neutrons in a nucleus together is known as the nuclear force. Protons and protons, neutrons and neutrons, or neutrons and neutrons can all be affected by this force. The nucleus is held together by this force.
The nucleus is at the center of an atom and accounts for the maximum mass of the atoms, a nucleus contains both protons and neutrons giving it an overall positive charge because the neutrons are of neutral or zero charges. As electrons are negatively charged and are very light in comparison to a proton or neutron, it is considered negligible in front of them. Due to the negative charge of the electron, it is under an attractive force known as the nuclear force from the nucleus, as we know opposite charges attract.

If an element has an atomic number of 15 then (a) the atomic mass must also be 15 (b) the atom has 15 electrons (c) there are 7 electrons in the outermost shell (d) the atom has 15 neutrons (e) the atom must have only one orbital
Answer:
if an element has atomic number of 15 then the atom has 15 electrons also.
Option (b)
Explanation:
remember the atomic number of an element is also the number of protons of that element, we know that protons have a positive charge, neutrons have no charge and electrons have a negative charge.
we also know that an element is atomically neutral, meaning it overall has no charge, this is because the positive proton attracts a negative electron and hence their charges cancel off.
this is why in all elements, the atomic number(proton number) will always be equal to the electron number.
Note the neutron number cannot be predicted this way, as far as I know, the neutron purpose is mainly to add Mass to the atom so that it can be more stable, though often times the neutron number is similar to the proton number also. You're not required to learn off atomic masses as far as I know because it will be given to you in the exams

Silicon Penta Fluoride: What is it?Fluoride in silicon pentoxide SiF₅ is a covalent compound created when silicon and fluorine share electrons. The 14th element, silicon, has four valence electrons. So, in order to reach octet, it needs 4 more electrons.
The 17th element, fluorine, has seven valence electrons. So, to reach an octet, one electron is required. Each F shares one of its valence electrons with silicon, giving silicon more electrons than an octet by receiving nine. Each of the five bonds is a single bond.

It is a state function that is frequently used in measurements of chemical, biological, as well as physical systems at constant pressure, which the sizable surrounding atmosphere conveniently provides. The pressure-volume term describes the effort needed to create space for the system by displacing it's own surroundings in order to determine its physical dimensions. For solids and liquids under typical conditions, the pressure-volume word is very small, whereas it is only moderately small for gases. Therefore, enthalpy serves as a stand-in for energy throughout chemical systems; enthalpy differences are what are commonly referred to as bond, lattice, and solvation "energies" in chemistry.

When solutions of strontium chloride and sodium sulfate react, which of the following is a spectator ion? A) strontium ion B) chloride ion C) sodium ion D) sulfate ion E) two of these
When solutions of strontium chloride and sodium sulphate react, two of these is a spectator ion.
So, option E is correct.
What do you mean by spectator ion?
Spectator ions may be either cations (positively-charged ions) or anions (negatively-charged ions). The ion is unchanged on both sides of a chemical equation and does not affect equilibrium. When writing a net ionic equation, spectator ions found in the original equation are ignored. Thus, the total ionic reaction is different from the net chemical reaction.
Spectator Ion Examples:
Consider the reaction between sodium chloride (NaCl) and copper sulfate (CuSO4) in aqueous solution.
2 NaCl (aq) + CuSO4 (aq) → 2 Na+ (aq) + SO42- (aq) + CuCl2 (s)
The ionic form of this reaction is:
2 Na+ (aq) + 2 Cl- (aq) + Cu2+ (aq) + SO42- (aq) → 2 Na+ (aq) + SO42- (aq) + CuCl2 (s)
The sodium ions and sulfate ion are the spectator ions in this reaction. They appear unchanged in both the product and reactant side of the equation. These ions just "spectate" while the other ions form the copper chloride. The spectator ions are canceled out of a reaction when writing the net ionic equation, so the net ionic equation for this example would be:
2 Cl- (aq) + Cu2+ (aq) → CuCl2 (s)

Answer is option B- Oxaloacetate/aspartate is an alpha-keto acid/alpha-amino acid pair used in transamination.
To create the amino acid version of the keto-acid and the keto-acid version of the original amino acid, amino groups are removed from amino acids and transferred to acceptor keto-acids by the process of transamination.
An amino group is transferred from one molecule to another during transamination. The formation of -ketoglutaric acid and aspartic acid from the interaction of glutamic acid and oxaloacetic acid serves as an example of this.
The reversible transfer of an amino group from glutamate to oxaloacetate, which results in the production of aspartate, is physiologically catalyzed by the enzyme AST. The enzyme was therefore previously known as serum glutamic-oxaloacetic transaminase.
Hence, Oxaloacetate/aspartate is an alpha-keto acid/alpha-amino acid pair used in transamination.
