Answer:
A. The equilibrium constant is very large
Explanation:
The equilibrium constant value is the ratio of the concentrations of the products over the reactants. When a chemical reaction goes to completion, that means that all the reactant has turned into products. As the equilibrium constant defines, it is the ratio of the product to the reactant. So at the final stage of the chemical reaction, the equilibrium constant will be very large.
<span>The oxygen atom accepts the proton. The oxidation number of O is -2, meaning that there are two unshared electrons in the valence shell; In the ClO- ion, one of these is shared with the Cl- ion, leaving an unshared electron on the oxygen atom, which is what the hydrogen atom shares its electron with, becoming the proton accepted by the O atom.</span>
Answer: A tropical year is longer than 12 lunar months and shorter than 13 of them. The arithmetical equation
12x12 + 7x13 = 235
allows it to be seen that a combination of 12 'shorter' (12 months) years and 7 'longer' (13 months) years will be equal to 19=12+7 solar years.
Explanation:
Solutes dissolve in solvents to form a solution. A saturated solution contains just as must solute as it can normally hold.
The solvent in the coffee solution is water and the rest of the chemicals dissolved in the solvent are called solutes. A solution is formed when a solute is dissolved in a solvent.
A saturated solution contains just as much solute as it can normally hold at a particular temperature while a supersaturated solution contains more solute than it can normally hold at a particular temperature.
A polar molecule contains covalent bonds between atoms having an electronegativity difference above 0.5. Such molecules are polar as electrons of the bond are drawn closer to the atom that is more electronegative.
According to Avogadro's law; 6.02 × 10^23 particles is referred to as one mole of particles.
A strong acid has a pH that may range from 0 - 3. A strong base has a pH of around 10 - 14. Water is a neutral substance and has a pH of 7.
From the information provided;
Number of moles of acid = 0.002 moles
Volume of solution= 2 L
Concentration of solution = number of moles/volume = 0.002 moles/2L = 0.001 M
pH = - log[H^+]
pH = - log[0.001 ]
pH = 3
From;
pH + pOH = 14
pOH = 14 - pH
pOH = 14 - 8.5
pOH = 5.5
pOH = - log[OH^-]
[OH^-] = Antilog[-5.5]
[OH^-] = 3.2 × 10^-6 M
