Answer:
a, b and c
Explanation:
To calculate molarity the number of moles and volume in dm3 is needed. So with the mass and molar mass the number of moles can be gotten and hence the molarity when dividing the number of moles by the volume in dm3.
D. F
Molecules are a group of bonded atoms but Fluorine stands on its own
B. HNO3 because it is copper and can not move the place of hydrogen's atom from the acid
Input of energy: swinging
Output of energy: hitting
Converter of energy: ball leaving the bat
I think these are correct
You are given two beakers, distilled water, two hot plates, two thermometers and salt. These materials are enough in order to test the effect of salt in the boiling point water. To do this, you set up two beakers. In one of the beakers, you add pure distilled water and nothing else. For the other beaker, you put a solution of salt and water. You place these beakers on separate hot plates and place inside the beakers the thermometers. You heat these substances until they boil and then you measure the boiling points of the substances. You would observe that the boiling point of the solution would have a higher boiling point than the pure liquid.
