Break apart 115 into 100 and 15.
100 = It already takes 1 hour FOR SURE.
Next, find the 15 part.
It is out of 100 so we divide 100 / 15 = .666666666666666666666666666...
Put them together and you get your answer.
Hope it helped! Please consider giving me brainliest!

Explanation:
Spectator ions refers to elements/molecules that do not form part of the reaction. Basically, these elements/molecules are in the same state in the reactant and product side. From the given reaction, Ca and SO4 change their state from aqueous to solid and Na and Cl do not change their state. Therefore, Na and Cl are spectator ions and Ca and SO4 are not spectator ions.
Answer:
The correct option is C.
Answer:
Density = Mass / Volume
V = 1.00 * 4.00 * 2.50 = 10 cm³
22.57 g/cm³ = Mass / 10 cm³
M = 22.57 g/cm³ * 10 cm³
M = 225.7 g
Answer: The mass of the block of osmium is 225.7 g.
