What is the molarity of a solution that has 26 moles of nacl in 2. 7 l of water?.
The molarity of a solution that has 26 moles of NaCl in 2.7L of water is 9.63M.
How to calculate molarity?The molarity of a solution can be calculated by dividing the number of moles of the solute by the volume of the solution as follows:
Molarity = no of moles ÷ volume
According to this question, a solution has 26 moles of NaCl in 2. 7 l of water. The molarity is as follows:
Molarity = 26mol ÷ 2.7L
Molarity = 9.6M.
Therefore, the molarity of a solution that has 26 moles of NaCl in 2.7L of water is 9.63M.

How do you figure out the number of protons in an atom?
How do you figure out the number of protons in an atom?
Answer:
Atomic number shows u the amount of protons there are in the atom
The protons are equal to the number of electrons
The group number tells you the number of electrons on the outer shell
(Sorry if u didn’t want the extra info but really it’s simple like magnesium has 12 so it has 12 protons/ 12 electrons)
Answer:
To calculate the numbers of subatomic particles in an atom, use its atomic number and mass number:
1. number of protons = atomic number.
2. number of electrons = atomic number.
3.number of neutrons = mass number - atomic number.

The Correct choice is : D
if temperature is held constant, then they have same average kinetic Energy because there's no change in energy caused by transfer of heat or something.
According to the forces of attraction, if temperature is constant the particles have the same average kinetic energy.
What are forces of attraction?Forces of attraction is defined as a force by means of which atoms in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in case of gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as the melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.

A sample of no2 occupies 16,500 ml at stp. How many no2 molecules are in the sample?.
According to Avogadro's law equal volume of all gases at the same temperature and pressure contain equal number of molecules. At STP one mole of any gas behaving ideally occupies a volume of 22.414 L.
What is molar volume?The volume occupied by one mole of a substance at a given temperature and pressure is defined as the molar volume at that temperature and pressure. The value of molar volume of an ideal gas at STP is important in stoichiometric calculations.
At STP, the number of molecules of a gas is given as:
Number of molecules of a gas (N) = V₀ in L / 22.414 × 6.022 × 10²³
Here V₀ in L = 16500 = 16.5 L
N = 16.5 / 22.414 × 6.022 × 10²³
N = 4.433 × 10²³
Thus the number of molecules present is 4.432 × 10²³.

Answer:
A high pressure area is an area where the air sinks. As it does, it warms up by the adiabatic effect of a greater pressure and that causes the clouds to evaporate, giving place to a clear sky
Explanation:
A high-stress area, high, or anticyclone, is a location in which the atmospheric stress on the surface of the planet is more than its surrounding environment.
What are the traits of the high-pressure system?In a high-Pressure system, it has better pressure in its center than in the regions around it. Winds blow away from excessive pressure.
Swirling withinside the contrary route from a low-stress system, the winds of an excessive pressure system rotates clockwise north of the equator and counterclockwise south of the equator.

A chemist dilutes a 1.0 ml sample of 2.0M KNO₃ by adding water to it. If the concentration of the solution that is obtained is 0.0080 m, then its volume is 250mL.
How do we calculate volume?Volume for the given equation will be calculated by using the below equation as:
M₁V₁ = M₂V₂, where
M₁ = molarity of KNO₃ = 2M
V₁ = volume of KNO₃ = 1mL
M₂ = molarity of final solution = 0.0080M
V₂ = volume of final solution = ?
On putting these values on the above equation, we get
V₂ = (2)(1) / (0.0080) = 250mL

An atom that has 84 protons and 86 neutrons undergoes a reaction. At the end of the reaction, it has 82 protons and 84 neutrons. What happened to the atom? It accepted radiation in a chemical reaction. It donated neutrons to another atom in a chemical reaction. It emitted an alpha particle in a nuclear reaction. It released a beta particle in a nuclear reaction.
Answer:
C
Explanation:
It denotes a loss of 2 protons and 2 neutrons for the atom. As a result, the atom released an alpha particle, which is composed of two protons and two neutrons, hence option C is correct.
What is an alpha particle?The structure of alpha particles, also known as alpha rays or alpha radiation, is similar to that of the helium-4 nucleus and is made up of two protons and two neutrons bonded together.
They often result from the alpha decay process, although they can also result from other processes.
If an atom has 84 protons and 86 neutrons, after the reaction, the atom has 82 protons and 84 neutrons, it suggests that the atom has lost 2 protons and 2 neutrons.
Therefore, the atom emitted an alpha particle in a nuclear reaction, hence option C is correct.

1. the imbalance of positive and negative charges.
Explanation
The electric dipole moment is a measure of the separation of positive and negative electrical charges within a system, that is, a measure of the system's overall polarity.
2.The atmosphere has recently changed and is mostly greenhouse gases, which have a large impact on climate
Explanation.
They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.
3.melted ice caps
explanation
A stronger greenhouse effect will warm the ocean and partially melt glaciers and ice sheets, increasing sea level. Ocean water also will expand if it warms overexcessively.
4.Yes, the greenhouse effect keeps the planet warm enough to support life.
Explanation
The greenhouse effect is a good thing. It warms the planet to its comfortable average of 59 degrees Fahrenheit (15 degrees Celsius) and keeps life on earth, well, livable. Without it the world would be a frozen, uninhabitable place, more like Mars.

Answer:
true
Explanation:
Covalent bonds are formed through the overlap of half-filled valence orbitals. Because of the overlapping, it is most probable that electrons are located within the region of the bond.
In order to make a covalent bond, the orbitals on each atom in the bond must overlap. Therefore, the given statement is true.
What is covalent bond?A covalent bond is an electron exchange usually results in the production of electron pairs between atoms. These electron couples are referred to as bonding pairs as well as sharing pairs. Covalent bonding seems to be the permanent equilibrium of atoms' forces of attraction versus attraction when atoms share electrons.
Because to electron sharing, each atom in a number of molecules can achieve the corresponding amount of the valence shell, resulting inside a stable electronic configuration. In organic chemistry, covalent bonds are far more common than ionic ones. In order to make a covalent bond, the orbitals on each atom in the bond must overlap.

For an impure sample of potassium hydrogen phthalate, the percentage of potassium hydrogen phthalate is
m'=39.3%
What is the percentage of potassium hydrogen phthalate if 2.81 g of the mixture required 35.61 mL of 0.152 mol/L NaOH to reach the end point?Generally, the equation for the mol base is mathematically given as
mol base = M*V
mol base = 0.152*35.61
mol base = 5.41272 mmol
In conclusion
mass = mmol/1000*MW
m== 5.41272 /1000*204.22
