Answer;
-Macroscopic properties remain constant
-Concentrations remain constant
-No change to copper solution seen;
-Rate of reverse/backwards reaction = rate of forward reaction;
Explanation;
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.
-It is a a condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs. A reversible chemical reaction is one in which the products, as soon as they are formed, react to produce the original reactants.
We are diploid organisms thus require two sets of chromosomes. In order to ensure the zygote is a diploid (has 2 sets of chromosomes) the gametes must be haploids (has 1 set of chromosomes) as two gametes join to make a zygote.
Having half the set of chromosomes also ensures that the offspring receives half of its chromosomes from its father and half from its mother. This becomes very important as to ensure there is genetic diversity in the offspring, both the fathers and mothers genes are needed.
The main class of high-temperature superconductors are in the class of copper oxides (only some particular copper oxides) especially the Rare-earth barium copper oxides (REBCOs) such as Yttrium barium copper oxide (YBCO).
<h3>What superconducting material works with the highest temperature?</h3>
As of 2020, the material with the highest accepted superconducting temperature is an extremely pressurized carbonaceous sulfur hydride with a critical transition temperature of +15°C at 267 GPa.
<h3>How do high-temperature superconductors work?</h3>
High-temperature superconductivity, the ability of certain materials to conduct electricity with zero electrical resistance at temperatures above the boiling point of liquid nitrogen, was unexpectedly discovered in copper oxide (cuprate) materials in 1987.

Answer is: mass of acetone is 22.51 grams.:
V(acetone - C₃H₆O) = 28.66 mL; volume.
d(acetone) = 0.7857 g/mL; density.
m(acetone) = V(acetone) · d(acetone).
m(acetone) = 28.66 mL · 0.7857 g/mL.
m(acetone) = 22.51 g; mass.
Acetone<span> or </span>propanone is the <span>colorless, volatile, flammable </span>organic compound (ketone).
1) Chemical reaction: HI(aq) → H⁺(aq) + I⁻(aq).
It gives an iodide anion.
2) Chemical reaction: H₂O → H⁺(aq) + OH⁻(aq).
It gives a hydroxide anion.
3) Chemical reaction: NH₄⁺(aq) → H⁺(aq) + NH₃(aq).
It gives ammonia.
4) Chemical reaction: HNO₃(aq) → H⁺(aq) + NO₃⁻(aq).
It gives nitrate anion.
