Answer:
0.625 kg
Explanation:
Since 90.6 is 3 half-lives from 30.2 (90.6/30.2 = 3) , divide the initial mass of the sample by 2, and divide that quotient by 2, and divide THAT quotient by 2 to determine how much remains after 3 half-lives.
Because of the fact that NaBr is an ionic bond, the bond is harder to break, therefore it needs more heat (or a higher temperature) to break it.
The atomic density cuases them to be different u can measure the weight mass density # 28 was cut off picture by the way
Answer:
Liquid volume is usually measured using either a graduated cylinder or a buret. As the name implies, a graduated cylinder is a cylindrical glass or plastic tube sealed at one end, with a calibrated scale etched (or marked) on the outside wall.
