Answer:
Explanation:
Lattice energy is a way to measure the bond strength in ionic compounds. Ionic compounds tend to have high melting and boiling points. Ionic compounds tend to be hard. Ionic compounds have a range of solubilities.
Answer:
The other name for this isotope is a proton. This is because it contains just a single proton.
Explanation:
H+
Protons = 1
Electrons = 1 - 1 = 0 (The + sign means it has lost a single electron)
Neutrons = 0
Answer: Option D) 2,700 Joules
Explanation:
Work is done when the force is applied in a specific direction. It is measured in joules. Thus, Workdone is the product of force and distance
Workdone = Force X Distance
Force = 90Newton
Distance = 30 metres
Workdone = 90N X 30m
Workdone = 2700 joules
The climber does work of 2,700 joules
Answer:
It’s not only about ‘changing light bulbs’ – it’s about changing attitudes and behavior.
Explanation:
When you are dealing with mole calculations, whatever you do to one side of the equation you must also do to the other. .5Fe is 1/8th of 4Fe, so in order to determine what it will yield you must divide the given amount of Fe2O3 and divide THAT by 1/8th, leaving you with .25 mol of Fe2O3.
