Replacement reaction.
Further explanationGiven
A chemical reaction
AB + C → CB + A
Required
reaction type
Solution
There are several types of reactions that can occur
synthesis: 2 elements combine to form a single product
polymerization: monomers combine to produce a polymer
decomposition: One compound breaks down into 2 components
oxidation : a change in oxidation number
replacement can be divided into 2
single replacement if one element replaces the other elements of a compound
double replacement if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds
AB + C → CB + A
If we look at this reaction, element C replaces element A to form a new compound CB. So it is single replacement. But this reaction can also be said to be an oxidation-reduction reaction because there is a change in oxidation number
element A undergoes a reduction reaction
element C undergoes an oxidation reaction
So types of redox reactions can be combination, decomposition, displacement, combustion, and disproportion.

The oxidation # (charge) of an element called "lindenium "Ld is + 1 and the oxidation # (charge) of an element called "mendezine symbol "Mz, is -2. What is the chemical formula for the compound called lindenium mendezide?
Answer:
Ld₂Mz
General Formulas and Concepts:
Chemistry - Compounds
Valence shellsWriting chemical compoundsBalancing chargesExplanation:
Step 1: Define
"Lindenium" Ld w/ oxidation charge of +1
"Mendezine" Mz w/ oxidation charge of -2
Step 2: Write Compound
To balance out the charges to be neutral (0), we must counter balance the amount of Ld's with Mz's. We need 2 Ld's with 1 Mz to create a compound with a neutral charge:
2Ld¹⁺ + Mz²⁻
2(+1) + (-2) = (+2) + (-2) = 0 (neutral charge)
Therefore, our compound must be Ld₂Mz.

Ed made pancakes from batter, freshly squeezed orange juice, fried eggs, and a strawberry fruit salad. Identify the chemical changes that occur to the food items during breakfast preparation
Answer:
Warming the batter and frying the eggs.
Explanation:
This is a chemical change as the products have very different property as compared to reactant not only physically but also chemically. Therefore, the reaction that is associated with cooking is combustion reaction.
What is chemical change?
Chemical change is a reaction in which breaking and forming of new bonds take place. One molecule completely converted to totally different molecule. The number of atoms remains same
One famous example of chemical change is the rusting of iron. The color, odor and arrangements of atoms in products are very much different from reactant. Chemical change are mostly irreversible in nature.
Cooking is a chemical change not a physical change. During cooking the reaction that is associated is combustion reaction as the by product is carbon dioxide and water.
Therefore, the reaction that is associated with cooking is combustion reaction.

There is a mixture of three gases. We know the total pressure is 2.50 atmosphere and the pressure of the oxygen and the nitrogen in the mixture are 0.52 atmosphere and 0.84 atmosphere. The jar containing the gases has a volume of 25.0 liters and is at a temperature of 32 degrees Celsius. What are the pressure and the number of moles of carbon dioxide in the container?
Answer:
1.14 atm and 1.139 mol
Explanation:
The total pressure of the container is equal to the sum of the partial pressure of the three gasses:
P = Poxygen + Pnitrogen + Pcarbon dioxide2.50 atm = 0.52 + 0.84 + Pcarbon dioxideNow we solve for the pressure of carbon dioxide:
Pcarbon dioxide = 1.14 atmTo calculate the number of CO₂ moles we use PV=nRT:
P = 1.14 atmV = 25.0 Ln = ?R = 0.082 atm·L·mol⁻¹·K⁻¹T = 32 °C ⇒ 32 + 273.16 = 305.16 K1.14 atm * 25.0 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 305.16 K
n = 1.139 molHow many H2O molecules are in 2 mol
Answer:
A mole of horses would be Avogadro number of horses (a lot actually !). Avogadro number is 6.023 x 10(23). A mole of H (hydrogen) atoms contains 6.023 x 10(23) H atoms. A mole of H2 molecules contains 6.023 x 10(23) H2 molecules or 2 moles of H atoms (since each molecules has 2 atoms).
Explanation:
Answer:
A mole (mol) is the amount of a substance that contains 6.02 × 10 23 representative particles of that substance. The mole is the SI unit for amount of a substance. Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.

how is the strength of an acid affected by the number of hydrogen ions it contains
Answer:
The greater the number of hydrogen ions, the increase in the acid strength.
Explanation:
Hydrogen ions determine the pH of the acid, greatest number of hydrogen ions give the pH value below 4 hence strong acid, and least number of hydrogen ions give a pH value above 4 but less than 7 hence a weak acid

How do the particies in a liquid create surface
tension?
It's been a while since I've taken Chemistry but here's what I know:
There are small, weak bonds that form between water molecules. These bonds make it so liquid molecules (water, in this example) cannot move as freely as a gas, but their bonds aren't nearly as strong as a solid. The bonds are formed when a hydrogen atom is attracted to an oxygen atom (because they have an opposite charge). This bond plus the gas molecules hitting the water causes surface tension.

In any chemical process, the matter is neither lost nor gained. *
reaction
conservation of matter
covalent bonds
physical change
In any chemical process, the matter is neither lost nor gained according to conservation of matter. Therefore, the correct option is option B.
What is matter?Matter is any material that has weight and occupies space by having volume in classical physics as well as general chemistry. All common items that can be felt are ultimately constituted of atoms, which are composed of colliding subatomic particles, therefore "matter" typically comprises atoms and everything made up of them, as well as any particles that act as if they both rest weight and volume.
It does not, however, contain massless particles like photons or even other energy phenomena and waves like light or heat. There are numerous states of matter (also known as phases). In any chemical process, the matter is neither lost nor gained according to conservation of matter.
Therefore, the correct option is option B.

Which of the following has the highest ionization energy?
a. F or I
b. Fr or C
c. Ne or Bi
d. Kor Kr
e. Ar or Mg
Answer:
helium
The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.

Tony sets up an experiment inside his classroom. He spaces 5 plants at equal distances along a straight line, with the first plant directly in front of a window and the last plant 10 meters (m) away from the window. He gives them equal access to air and water and then monitors the amount of gas each plant releases.
Which gas is Tony monitoring and what trend is he most likely to see in the data he collects?
He is monitoring oxygen. The amount of gas released should be highest for the plant in the middle and lowest for the plants at the ends.
He is monitoring carbon dioxide. The amount of gas released should be highest for the plant in the middle and lowest for the plants at the ends.
He is monitoring oxygen. The amount of gas released should be highest for the plant closest to the window and lowest for the plant farthest away from the window.
He is monitoring carbon dioxide. The amount of gas released should be highest for the plant closest to the window and lowest for the plant farthest away from the window.
