multiplying terrorist to power 23, divided by 96. Multiplied by 12.7. so this is 76.48
7.96 x 10²² particles would be found in a 12.7g sample of ammonium carbonate. A particle is a tiny, localized item.
What is particles in chemistry?A particle is a tiny, localized item that may be defined by a number of physical or chemical characteristics, including volume, density, and mass. They range significantly in size or number from tiny particles like atoms to subatomic particles such as the electron.
Depending upon their density, particles can potentially be utilized to mimic even bigger things, such as moving celestial bodies or a throng of people. Although the meaning of the word particle is quite broad, different scientific disciplines might refine it as necessary. Any substance made up of particles is referred to as a particulate.
number of moles = given mass/ molar mass
= 12.7/ 96.08
= 0.13moles
number of particle= 0.13 × 6.022×10²³
= 7.96 x 10²²
Therefore, 7.96 x 10²² particles would be found in a 12.7g sample of ammonium carbonate.

What happens when a solid is dissolved into a liquid?
O Solid particles float toward the surface layer of liquid particles.
O Solid particles sink down toward the bottom layer of liquid particles.
O Solid particles become evenly dispersed among liquid particles.
O Solid particles become suspended in the middle of liquid particles.
When a solid dissolves in a liquid to form a solution, solid particles become evenly dispersed among liquid particles.
What are solutions?Solutions are formed when a solute particle dissolves in another substance known as a solvent.
Usually, solutions are formed when solids dissolve in liquids.
The solid is the solute while the liquid is the solvent.
When a solid dissolves in a liquid, solid particles become evenly dispersed among liquid particles.
Therefore, solutions are formed when solute particles dissolve in solvents.

The pressure of x ml of a gas was increased from 2 atm to 4 atm at constant temperture. what will be the new volume?
The new volume of the gas given the data from the question is 1/2X mL
Data obtained from the question
Initial volume (V₁) = X mL
Initial pressure (P₁) = 2 atm
New pressure (P₂) = 4 atm
New Volume (V₂) = ?
How to determine the new volume
The new volume of the gas can be obtained by using the Boyles’ law equation as illustrated below:
P₁V₁ = P₂V₂
2 × X = 4 × V₂
2X = 4V₂
Divide both side by 4
V₂= 2X / 4
V₂ = 1/2X mL

during an experiment, the percent yield of calcium chloride from a reaction was 80.34%. theoretically, the expected amount should have been 115 grams. what was the actual yield
from this reaction?
caco, + hc - cacl + co, + h20 (5 points)
a. 090.1 grams
b. 92.4 grams
c. 109.2 grams
d. 115.3 grams
The actual yield of the experiment given the data from the question is 92.4 g (Option B)
What is percentage yield?This is the ratio of the actual yield to the theoretical yield of a given reaction multiplied by 100
Percentage yield = (Actual / Theoretical) × 100
What is actual yield?This is the amount obtained from the expriment procedures
What is theoretical yield?This is the amount obtained from simple calculations as regarding the experiment.
How to determine the actual yieldPercentage yield = 80.34%Theoretical yield = 115 gActual yield =?Actual yield = percentage yield × theoretical yield
Actual yield = 80.34% × 115
Actual yield = 0.8034 × 115

An atom has eight protons and nine neutrons. draw the atomic structure of the atom
An atom has eight protons and nine neutrons. The atomic structure of the atom is attached below in image.
What is an atomic structure ?The term "atomic structure" describes the structure of an atom, which has a nucleus that contains both protons and neutrons . The centre of the nucleus is circled by the negatively charged electrons.
The smallest piece of ordinary matter within an element is called an atom. Protons, neutrons, and electrons are the three subatomic particle types that make up an atom.
An isotope's number is equal to the sum of its protons plus neutrons since their masses are almost identical. Oxygen 16 therefore has 8 protons and 8 neutrons, followed by oxygen 17 with 8 protons and 9 neutrons, and oxygen 18 with 8 protons and 10 neutrons.

how can you explain that even though you continue to add pure water into a substance, even though the resultant ph might differ a little, the acidity or alkalinity of substance still remains the same to that of substance?
Addition of pure water does not change pH of a solution because pure water has neutral pH.
Why the pH does not change when pure water is added?Even though you continue to add pure water into a substance, the acidity or alkalinity of substance still remains the same to that of substance because pure water has neutral pH which can't change the acidity or alkalinity of a solution.
So we can conclude that addition of pure water does not change pH of a solution because pure water has neutral pH.
