The correct name of the compound CuCl is copper I chloride.
An ionic compound is formed two atoms when one loose electrons and the other atoms gains those electrons. Ionic bonds are actually an ion pair, a pair of oppositely charged ions held together by electrostatic interaction. Transition metals are elements with incompletely filled d orbitals. Copper is a transition element.
The compound CuCl is named copper I chloride. We can see that the copper is in the +1 oxidation state in this compound hence the name.

What kind of feature results from the convergence of two oceanic plates?
Answer: When a convergent boundary occurs between two oceanic plates, one of those plates will subduct beneath the other. Normally the older plate will subduct because of its higher density. The subducting plate is heated as it is forced deeper into the mantle, and at a depth of about 100 miles (150 km) the plate begins to melt.

which molecules are required for the citric acid cycle to fully oxidize the carbons donated by acetyl coa?
Explanation:
At the start of the citric acid cycle, a molecule of oxaloacetate accepts a two-carbon acetyl group from acetyl CoA to form citrate. This reaction kicks off the citric acid cycle; thus, oxaloacetate is required for the cycle to take place.
To begin the citric acid cycle, an oxaloacetate molecule accepts a two-carbon acetyl group from acetyl CoA to form citrate. Because this reaction initiates the citric acid cycle, oxaloacetate is required for the cycle to occur.
What is citric acid cycle ?The Krebs cycle, also known as the citric acid cycle or TCA cycle, is a chain of reactions that occurs in the mitochondria and is used by almost all living cells to produce energy through aerobic respiration. It consumes oxygen and emits water and carbon dioxide as byproducts.
All aerobic organisms use a series of chemical reactions to generate energy by converting acetate derived from carbohydrates, fats, and proteins into carbon dioxide.
The citric acid cycle involves the attachment of an acetyl group from acetyl CoA to a four-carbon oxaloacetate molecule to form a six-carbon citrate molecule.
Thus, Citrate is oxidized in a series of steps, releasing two carbon dioxide molecules for each acetyl group fed into the cycle.

Difference Between baking soda and baking powder
Answer:
Baking soda is sodium bicarbonate, which requires acid and a liquid to become activated and help baked goods rise. Conversely, baking powder includes sodium bicarbonate, as well as an acid. It only needs a liquid to become activated. Substituting one for the other is possible with careful adjustments. Baking soda is strong. In fact, it is about 3-4x stronger than baking powder. More baking soda in a recipe doesn't necessarily mean more lift.
Explanation:
Explanation:
baking soda contains one ingredient, sodium bicarbonate. however, baking powder contains sodium bicarbonate , monocalcium phosphate and either sodium acid prophetess or sodium aluminum sulfate

Block A is made of copper, which has a specific heat value of 0.385 J/g*C.
Block B is made of aluminum, which has a specific heat value of 0.900
J/g*C. Both blocks have a mass of 100 grams. If you are trying to heat the
blocks to a temperature of 200 C, which block will need to absorb more
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.
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.

(Hope this helps can I pls have brainlist (crown)☺️)
The empirical formula of a compound that contains only iron and oxygen and is 22.27% oxygen is FeO. The correct option is A.
What is the empirical formula?The simplest whole number ratio of atoms in a chemical molecule is its empirical formula. The empirical formula is the chemical formula that gives the number of atoms of the chemical formula that is given in the chemical reaction.
For example, the C₆H₁₂O₆ is the formula of glucose. The simplest formula is CH₂O. This will be the simplest ratio of this compound. The first one, this C₆H₁₂O₆ is the molecular formula.
It only contains the element one quantity. The empirical formula that contains oxygen and iron will be FeO. The empirical formulas is calculated by dividing the simplest formula.

how does decreasing the temperature affect the volume of gas??
Answer: Well, when you decrease the temperature in a gas the volume will decrease as well as the pressure. Since, heating a gas or liquid increases the temperature/pressure. Therefore, it'd increase the volume but since the temperature is decreasing the volume of the gas does too.
A mixture of hydrogen, nitrogen, and water vapor has a total pressure of 864 mmHg. The partial pressure of hydrogen is 220 mmHg and that of nitrogen is 410 mmHg. What is the partial pressure of water vapor?
Answer:
As per Dalton's law of Partial pressure,
The total pressure of a mixture of gases is equal to sum of partial pressure of individual components of the mixture.
So,P=P_H+P_N+P_WP=P

What is partial pressure?
The force that a gas exerts is known as partial pressure. The total pressure of a mixture of gases is equal to the sum of their partial pressures.
Partial pressure can be calculated by using the formula: [tex]P_{Total} =P_{N} +P_{H} +P_{H}[/tex]

Since we know the products and one of the reactions, we can work backward to discover what the other reactant may be.
As it is in the question, we can map the reactants and product:
Reactants Product
Ammonium Ammonia
Sulfate Sulfate
________ Potassium
________ Water
Since the reaction will yield Potassium and water, the likely reactant is Potassium Hydroxide (KOH). This is because we know that Ammonium lost a Hydrogen atom that could combine with the Hydroxide radical to form water.
This becomes clear when we consider the net ionic equation:
Ammonium sulphate + Potassium Hydroxide → potassium sulfate + ammonia + water
if we write this a balanced chemical equation:
(NH₄)₂SO₄ + 2KOH → K₂SO₄ + 2NH₃ + 2H₂O
if we write the reaction as an ionic equation
2NH₄⁺ + SO₄⁻ + 2K⁺ + 2OH⁻ → 2K⁺ + SO₄⁻ + 2NH₃ + 2H₂O
if we remove the ions that appear on both the reactant and product side (spectator ions)
2NH₄⁺ + 2OH⁻ → + 2NH₃ + 2H₂OIf you were able to magnify a penny down to the atomic level, what two

We can use the formula M₁V₁ = M₂V₂ the total volume of water that will yield 0.800 M HCl. We can then subtract that from the initial volume to get how much water needs to be added.
Since M₁V₁ = M₂V₂ (starting mole× starting volume = end mole × end volume)
⇒ (5 mol)(20 mL) = (0.80 mol) V₂
100 mol/mL = 0.8 mol × V₂
⇒ V₂ = 100 mol/mL ÷ 0.8 mol
= 125 m
Since we began with 20.0 mL of water,
water needed to add = 125 mL - 20 mL = 105 mL
During recrystallization, why is it necessary to cool the solution slowly?
answer:
the reason is to ensure more solute is dissolving as it cools down. it is important to do it slowly because water will be sucked into buchner flask by a partial vaccum through the rubber tubing and be able to arrange molecules.
