What are electrons in the outermost energy shell of an atom called
Which two subatomic particles have about the same mass
Protons and neutrons have about the same mass.
Which type of reaction is the burning of gasoline to release heat energy
What term describes an energy resource that can be used up
Which type of force is exerted on the bottom row of bricks in a building
Which type of compound is composed of negatively and positively charged atoms
Ionic compounds are composed of negatively and positively
charged atoms.
Is a substance with equal numbers of H ions of OH - ions an alkaline solution
No. If the number of H+ and OH- ions are equal then the solution
is neutral. A solution is considered alkaline if it has more OH-
ions than H+ ions.
What infroemation is needed to calculate the amount of energy needed to heat a volume of water to some temperature
You need to know the amount of water (mass), how many degrees
you want to heat it up, and the specific heat of water. Then - if
everything is in compatible units - you must simply multiply the
three together.
What term best defines two or more atoms joined by a chemical bond-
The term that best defines two or more atoms joined by a
chemical bond, is a covalent bond.
