An irish natural philosopher, robert boyle, conducted experiments to verify properties of gases discovered by other scientists. boyle's law mathematically describes the inversely proportional relationship between the absolute pressure and volume of a gas. this means that if the volume of a container of gas is decreased, the amount of pressure in that container will increase proportionally. this relationship is a (2 points)

select one:
a. theory because it is a description based on mathematics.
b. theory because it describes a relationship without trying to explain it.
c. law because it describes how one variable affects another.
d. law because it is a description but not an explanation.

Amass of 100.0 g of solute is dissolved in water so that 850. ml of a 0.7500 m solution has been prepared. what is the molar mass of the solute?

There is a single path for electrons. the current decreases when additional resistors are added. the current will be the same in each resistor. these statements best describe a(n) circuit.

Part b: study of equilibrium on solubility: mg(oh)2(s) ⇌ mg2+(aq) + 2 oh–(aq) cloudy clear (pink) 7. a. b. 8. a. b. 9. 10. 11. 12. when adding concentrated hydrochloric acid, how did the appearance of the equilibrium mixture change? the change in appearance indicated a shift in the point of equilibrium. in which direction did the equilibrium shift? (l) left (r) right explain your answer to question 7a. you should indicate which ion was added to or removed from the equilibrium mixture. when adding edta, how did the appearance of the equilibrium mixture change? the change in appearance indicated a shift in the point of equilibrium. in which direction did the equilibrium shift?
