Explanation:
Mass of metal = mass of the flask and stopper with metal - mass of the flask and stopper empty
As per the data given:
Mass of the flask and stopper with metal = 144.076 g
Mass of the flask empty: you did not includ this information, but I searched it and found that the mass of the flask and stopper is 33.695 g
Then, the anwser is:
mass of metal = 144.076 g - 33.695 g = 110.381 g
Answer:
crushing an ice cube
Explanation:
crushing an ice cube can be redone by freezing it again in its position
A 3 should be placed in front of the H2 to balance it, since the 2 in front of NH3 says there are 6 H atoms. However on the other side, there are only 2. If we add the 3, 3 x 2 = 6. Then it is balanced.
