Which equation is an equation of a circle with a radius of 3 and its center is at (5, -2)? (x - 5)² + (y + 2)² = 9

(x + 5)² + (y – 2)² = 3

(x - 5)² + (y + 2)² = 3

(x + 5)² + (y - 2)² = 9

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.

What happened to the amount of carbon dioxide in the atmosphere from 2010–2017?

For each of the following compounds, decide whether the compound's solubility in aqueous solution changes with ph. if the solubility does change, pick the ph at which you'd expect the highest solubility. you'll find ksp data in the aleks data tab. compounds does solubility change with ph
