Answer:
None of the above
Explanation:
Work is defined as the force that moves an object through a particular distance:
Workdone = force x displacement
At constant velocity, the force on a body is zero because such a body is not accelerating.
Force is a product of mass and acceleration. Acceleration occurs only when velocity changes with time. If no change in velocity, acceleration does not occur. Therefore, no force is being applied.
From all the situations given, the condition is set at constant velocity. At constant velocity, there is no acceleration. This implies that no work is done.
The solubility product constant of a compound is calculated by the product of its corresponding ion concentration. The dissociation reaction would be as follows:
SrCO3 = Sr2+ + (CO3)2-
Ksp = [Sr2+] [CO3] = <span>5.60 × 10^-10
</span>5.60 × 10^-10 = x^2
x = 2.37x10^-5 mol/L = 3.49x10^-3 g/L

Explanation:
In the field of organic chemistry, keto–enol tautomerism refers to equilibrium of chemical substance that is among a keto form (an aldehyde or a ketone) and an enol (an alcohol). The enol and the keto forms are believed to be tautomers of each other. The keto form preponderate at equilibrium for a large amount of ketones.

An acid has several definitions one would be that it is a proton donor and an electron donor. Also, it said to produce an H+ ion when in solution. For nitric acid in solution, it dissociates into ions which are NO- ions and H+ ions. So, it must be an acid. It has a dissociation reaction:
HNO3 = H+ + NO3-
