Answer:

Explanation:

Concentration of Cu⁺² = 9.25 x 10³ M

Concentration of Mn⁺² = 1.4 x 10² M

solubility product of copper carbonate = 7.08 x 10⁻⁹

solubility product of manganese  carbonate = 2.24 x 10⁻¹¹

solubility product of later is less so carbonate of manganese will come out first .

B )

[ Mn⁺² ] [ CO₃⁻² ] = 2.24 x 10⁻¹¹

1.4 x 10²  [ CO₃⁻² ] = 2.24 x 10⁻¹¹

[ CO₃⁻² ] = 1.6 x 10⁻¹³ .

the concentration of carbonate ion when this precipitation first begins

= 1.6 x 10⁻¹³ M .

Answer:

The ion is d^10

Explanation:

Tetrahedral geometry is one in which the central atom/ion is located at the center of four ligands positioned at the corners of a tetrahedron.

It is different from a square planar complex wherein the ligands are positioned at the corners of a square with the central atom/ion at the center of the square.

Tetrahedral complexes are more common with d^10 species.The electronic configuration of Cu I is [Ar]3d104s1. Hence, a tetrahedral geometry is preferred over a square planar geometry.

Answer: For example, uranium can fission to yield strontium and krypton. Fusion joins atomic nuclei together. The element formed has more neutrons or more protons than that of the starting material. For example, hydrogen and hydrogen can fuse to form helium.

Answer:

Valence electrons are the electrons in the outermost energy level of an atom — in the energy level that is farthest away from the nucleus. Being able to determine the number of valence electrons in a particular atom gives you a big clue as to how that atom will react.

Answer:

ATP

Explanation:

it is made by breaking glucose down

Answer:

Once the last phosphate group is removed from the ATP molecule by hydrolysis, it will form ADP plus inorganic phosphate. ADP is a lower energy molecule. The release of energy during hydrolysis of ATP can be harnessed by the cell to do work. Living things continuously use ATP but it is renewable and can be recycled.

Answer:

Smaller than the object

Real

Upside down

Explanation:

The image formed by a convex lens will always be real and smaller. The image formed is smaller than the object, real ,upside down and right side up. Hence, options 1,2,3 and 5 are correct.

Convex lens is a type of lens, in which one at least one side is curved outside. These lenses have the ability to focus an outside light beam to a spot on the opposite side by converging it.

The focal length of the convex lens is the distance from the lens's center to this point, which is known as the focus. On the other hand, a plano-convex lens has one surface that is flat and the other that is convex.

Convex lenses cause light from an item to bend, creating an upright, smaller, and inverted picture of the original object. As a result, the candle in this instance will be smaller, upside down, and actual.

Explanation:

The substance under analysis must be a polar organic substance of high molecular mass. We must remember that as the magnitude of dispersion forces increases with increase in molecular mass, the melting point increases accordingly. Also polar organic substances have very high melting points due to the presence of polar bonds in the molecule..

Hence the intramolecular forces in the substance are covalent bonds while the intermolecular forces are both dispersion forces and dipole forces.

The substance may likely be 1,2,3,4,6,7,8-Heptachlorodibenzo-p-Dioxin which a white powder and melts at 264 °C.

Answer:

a. precipitation

Explanation:

In the reaction:

Ni²⁺(aq) + 2NaOH(aq)→ Ni(OH)₂(s) + 2 Na⁺

Nickel is precipitated as Ni(OH)₂ producing Na⁺ ions.

In a precipitation two soluble ions react with each other to produce an insoluble salt.

In our problem, Ni²⁺ is reacting with OH⁻ to produce Ni(OH)₂, an insoluble salt

The reaction is a precipitation

In an acid-base reaction, an acid reacts with a base to produce water and a salt. In this problem is a base reacting (NaOH) but there are no acids in the reaction.

And in a redox reaction an ion is been oxidized whereas the other is been reduced (Loosing electrons and gaining electrons).

As you can see, Ni²⁺ still with oxidation number of 2+ in Ni(OH)₂ and Na⁺ is always +1-. Thus, this is not a redox reaction.

Answer:

Products

Explanation:

Reactants → Products

Chemical reactions are characterized by the formation of new products, and the making and breaking off strong chemical bonds.

Answer: They are the PRODUCTS of the reaction.

Explanation: In a chemical reaction, there are the REACTANTS and the PRODUCTS.

The reactants are the "ingredients" in the chemical formula. They are what are being chemically combined in a way.

The products are the "meal," or what the reactants combined to create.

For example, when creating salt or NaCl, this is essentially the formula:

In this formula, Na (sodium) and Cl (chlorine) are the reactants. NaCl (sodium chloride, aka salt) is the product.

I hope this clears things up, and I hope this was the context in which the question was asked!

Answer: A single replacement reaction looks sort of like this

A + BC —> AC + B

Explanation: It would be a LOT more helpful for us if you had provided the answer choices for this question, but I'll try to help by explaining WHAT single-replacement reactions are.

Single-replacement reactions are reactions in which one ion displaces another to form a new compound . One reactant is an element; one reactant is a compound . One product is an element; one product is a compound . The reactant element is part of the compound product .
