When the product is added to the solution, it will shift the reaction forward.
What is Carbonation?Carbonation is a form of chemical reaction in which carbon dioxide is added to a solution to give carbonates, bicarbonates, and carbonic acid. In chemistry, the term is used in place of carboxylation to form carboxylic acids
When a product is added to a system, the equilibrium will shift to the left, so as to produce more reactants but if the reactants is remove from the system, equilibrium will also be shifted to the left.
Therefore, When the product is added to the solution, it will shift the reaction forward.

In a molecule of water (H2O), two hydrogen atoms are each bonded to one oxygen atom. What forms each of the two bonds?
A rigid, non-flexible container of O2 gas is being transported to a hospital. What will most likely happen if the vehicle is left unattended and the temperature of the O2 rises?
A. The pressure will increase and the container will leak or explode. B. The pressure will decrease and the container will leak or explode. C. The pressure will increase, but the particles will condense within the container. D. The pressure will decrease and the container will maintain its current temperature.
If the temperature of the O2 in the container rises as a result of being abandoned for quite some time, the pressure in the container will increase and this may either lead to an explosion or leakage of the gas.
What is the relationship between temperature and pressure of a gas?At constant volume, the pressure of a gas increases with increased temperature as a result of an increase in the average kinetic energy of the gas molecules which increases the collision rate among the molecules.
Thus, if the temperature of a gas in a container increases, the pressure inside the container will also increase. This may lead to the gas leaking from the container or the container may even outrightly explode due to pressure.

What is the role of meteorites in the formation of life?
Answer:
Meteorites are consensually considered to be involved in the origin of life on this Planet for several functions and at different levels: (i) as providers of impact energy during their passage through the atmosphere; (ii) as agents of geodynamics, intended both as starters of the Earth’s tectonics and as activators of local hydrothermal systems upon their fall; (iii) as sources of organic materials, at varying levels of limited complexity; and (iv) as catalysts.

Answer:
acidic,non polar,basic
Explanation:
that’s the ones I put and I got a 100% on my test just now
The types of R groups that can exist in amino acids include acidic, non-polar, basic, and polar groups.
1. Acidic R groups: These groups have a negative charge and can donate a proton (H+). An example of an amino acid with an acidic R group is aspartic acid (Asp) or glutamic acid (Glu).
2. Non-polar R groups: These groups are hydrophobic and do not have a charge. They are composed mainly of carbon and hydrogen atoms. Examples of amino acids with non-polar R groups include alanine (Ala), valine (Val), and phenylalanine (Phe).
3. Basic R groups: These groups have a positive charge and can accept a proton. An example of an amino acid with a basic R group is lysine (Lys) or arginine (Arg).
4. Polar R groups: These groups are hydrophilic and have a partial charge. They can form hydrogen bonds with other polar molecules. Examples of amino acids with polar R groups include serine (Ser), threonine (Thr), and asparagine (Asn).
Thus, types of R groups that can exist in amino acids include acidic, non-polar, basic, and polar groups.

5.00 L of a gas is known to contain 0.965 mol. If the amount of gas is increased to 1.80 mol, what new volume will result ( at an unchanged temperature and pressure) ?
SHOW YOUR SOLUTION.
At an unchanged temperature and pressure, if the amount of gas increased by the given value, the final or new volume of the gas is 9.33L
Avogadro's lawAvogadro's law states that equal volumes of different gases contain an equal number of molecules provided temperature and pressure remains in the same conditions. It is expressed;
V₁/n₁ = V₂/n₂
Given the data in the question;
Initial volume; V₁ = 5.0L Initial amount of gas; n₁ = 0.965mol Final amount of gas; n₂ = 1.80mol Final volume; V₂ = ?To determine the new volume, we substitute our given values into the expression above.
V₁/n₁ = V₂/n₂
V₁n₂ = V₂n₁
V₂ = V₁n₂/n₁
[tex]V_2 = \frac{5.00L * 1.80mol}{0.965mol}\\\\V_2 = \frac{5.00L * 1.80}{0.965}\\\\V_2 = \frac{9L}{0.965} \\\\V_2 = 9.22L[/tex]
Therefore, at an unchanged temperature and pressure, if the amount of gas increased by the given value, the final or new volume of the gas is 9.33L

A 1.775g sample mixture of potassium hydrogen carbonate is decomposed by heating. if the mass loss is 0.275g what is the percentage of khco3
A 1.775g sample mixture of KHCO₃ is decomposed by heating. if the mass loss is 0.275g, the mass percentage of KHCO₃ is 70.4%.
What is a decomposition reaction?A decomposition reaction can be defined as a chemical reaction in which one reactant breaks down into two or more products.
Step 1: Write the balanced equation for the decomposition of KHCO₃.2 KHCO₃(s) → K₂CO₃(s) + CO₂(g) + H₂O(l)
The mass loss of 0.275 g is due to the gaseous CO₂ that escapes the sample.
Step 2: Calculate the mass of KHCO₃ that formed 0.275 g of CO₂.In the balanced equation, the mass ratio of KHCO₃ to CO₂ is 200.24:44.01.
0.275 g CO₂ × 200.24 g KHCO₃/44.01 g CO₂ = 1.25 g KHCO₃
Step 3: Calculate the mass percentage of KHCO₃ in the sample.There are 1.25 g of KHCO₃ in the 1.775 g sample.
%KHCO₃ = 1.25 g/1.775 g × 100% = 70.4%
A 1.775g sample mixture of KHCO₃ is decomposed by heating. if the mass loss is 0.275g, the mass percentage of KHCO₃ is 70.4%.

Does electronegativity affect replacement reactions
Elecetronegativity will affect the replacement reactions as it attracts the bonded electrons towards itself.
What is replacement reaction?Replacement reactions are those reactions in which replacement of any one element from any compound is done by any other element.
Electronegativity is the attracting power of any element to hold the bonded electron towards itself so that they will bear a partial negative charge on itself. If in any reaction replacement of anion is required and any compound have more electronegative element which bounded the bonded electron strictly and will not allow the formation of anion then it affects the activity of the reaction.
Hence electronegativity affect the replacement reactions.

Answer these questions based on 234. 04360 as the atomic mass of thorium-234. The masses for the subatomic particles are given. Round the mass defect to the 5th decimal place. Mass of a proton: 1. 00728 amu mass of a neutron: 1. 00866 amu How many protons does Thorium have? How many neutrons does Thorium-234 have? Calculate the mass defect for the isotope thorium-234 = amu.
The mass defect for the isotope thorium-234 if given mass is 234.04360 amu is 1.85864 amu.
How do we calculate atomic mass?Atomic mass (A) of any atom will be calculated as:
A = mass of protons + mass of neutrons
In the Thorium-234:
Number of protons = 90
Number of neutrons = 144
Mass of one proton = 1.00728 amu
Mass of one neutron = 1.00866 amu
Mass of thorium-234 = 90(1.00728) + 144(1.00866)
Mass of thorium-234 = 90.6552 + 145.24704 = 235.90224 amu
Given mass of thorium-234 = 234.04360 amu
Mass defect = 235.90224 - 234.04360 = 1.85864 amu
Hence required value is 1.85864 amu.
