The figure above shows two closed containers. Each contains the same volume of acetone in equilibrium with its
Yanar at the same temperature. The vapor pressure of the acetone is
Answers
The vapor pressure of a liquid and the prevailing atmospheric pressure,
determines the boiling point temperature.
The vapor pressure of the acetone is the same in both containers because
the temperature is the same.
Reasons:
The vapor pressure of a liquid is the pressure at which the number of
molecules entering the gaseous phase are in (dynamic) equilibrium with
the number of molecules entering the liquid phase.
The factors that affect vapor pressure are;
The type of molecules that make up the liquid or solidThe temperature of the liquid or solidChanging the surface area changes the instantaneous concentration of
molecules of vapor above the liquid, however, an equilibrium vapor
pressure is reached with time as more molecules enter or exits the liquid
(or solid) due being over or under saturated.
Therefore, the surface area of the liquid has no effect on a liquid's vapor
pressure therefore;
The vapor pressure in both containers will be the same because the temperature is the same.

Type the formula "H2" into the Reactants box. What is the molar mass of hydrogen gas, H2?
Answers
The molar mass of hydrogen gas H₂ is 2.016 grams.
What is molar mass?The mass of a substance divided by its concentration, expressed in grams per mole (g/mol), is known as its molar mass.
Mass is the quantity of matter in a physical body. The product of the molar mass of the compound and the moles of the substance are defined as mass.
The mole is a SI unit of measurement that is used to calculate the quantity of any substance.
M = m /n
M = molar mass
m = mass of a substance (in grams)
n = number of moles of a substance
The mass of hydrogen is 1
The number of moles of hydrogen is 6.022 x 10²³
Hydrogen gas has a molar mass of 2.016 grams per mole. When two hydrogen atoms join forces to create a molecule with the formula H2, hydrogen gas is created.
Therefore, the molar mass of hydrogen gas H₂ is 2.016 grams

Answers
Answer:
protons and neutrons
Explanation:
Neutrons and protons are the particles that are found in the nucleus of an atom.
What are protons and neutrons?Protons and neutrons are subatomic particles. They are present in the nucleus of an atom and constitute most of the mass of the atom. There are three kinds of subatomic particles that are present in an atom.
These are -
Electrons: Electrons are negatively charged particles. These are present in the atomic shells of the atom. The number of electrons in the last shell of the atom constitutes the valency of the atom. Protons: Protons are positively charged particles. These are present in the nucleus of the atom.Neutrons: Neutrons are neutral molecules with no charge. These are also present in the nucleus of the atom.Since most of the mass of the atom, in the form of protons and neutrons, is present in the nucleus, the mass number is denoted as the sum of the number of protons and neutrons. Protons and neutrons together are sometimes also called nucleons.
Therefore, neutrons and protons are present in the nucleus of an atom.

energy?
o Block A (copper) because it has a lower specific heat value.
o Block B (aluminum) because it has a higher specific heat value.
o Block A (copper) because it has a higher specific heat value.
o Block B (aluminum) because it has a lower specific heat value.
Answers
Block B will need to absorb more energy as it has higher specific heat value.
What is specific heat?Specific heat is defined as the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius rise. Units of specific heat are calories or joules per gram per degree Celsius.
Specific heat capacity varies with temperature often and is different for each state of matter. While the substance which undergoes phase transition then it's specific heat is technically infinite.
Specific heat of a gas is significantly higher when it is allowed to expand as it is heated .It may also be referred to as a ratio between the specific heat capacities of two substances at a given temperature.It is calculated by the formula ,Q=mcT
For copper, it is 100×0.385×473=18210.5 J
For aluminium ,it is 100×0.90×473=42570 J
As the specific heat of aluminium is higher it will absorb more energy.

What will be the new pressure of a gas at 36.0 atm and 108 C if the temperature of the gas is increased to 441 C?
Answers
Answer
199 ATM
EXPLANATION
assume that the volume is constant. At higher temp the gas molecules move faster and the pressure goes up.
P=kT
CONVERT C TEMP TO K TEMP FOR GAS PROBLEMS!!!!!!
108C = 108 +273 = 381 K
441C = 441 + 273 = 714K
P=kT
108 =k x 381
K=108/381 = 0.279
AT THE HIGHER TEMP
P =0.279 X 714 =199ATM

in an oxidation-reduction reaction, how is the reducing agent changed?
Answers
Explanation: The additional terminology comes from the definition that, within redox processes, a reductant transfers electrons to an oxidant; hence, the reductant (reducing agent) loses electrons, so is oxidized, while the oxidant (oxidizing agent) gains electrons, so is reduced.
In an oxidation-reduction reaction, the reducing agent loses electrons and loses potential energy, Therefore, option (C) is correct.
What is a reducing agent?A substance that loses its electrons in a redox reaction to other substances and gets oxidized is called a reducing agent. A reducing agent is one of the reactants which reduces the other reactant by donating the electrons to the reactant of an oxidation-reduction reaction.
If the reducing agent can't pass electrons to another reactant in a reaction, then the reduction process does not occur and the reaction cannot proceed.
In redox reactions, when an electron loses potential energy as a result of the transfer and energy is released. Electrons with more potential energy are associated with less electronegative atoms and less potential energy is associated with a more electronegative atom (such as O).
Therefore, the reducing agent loses electrons and loses potential energy in a redox reaction.
