__ Hg + __O2 ⟶__ HgO

3. Nitrogen and oxygen combine to produce dinitrogen pentoxide. If you want to produce 12.99 moles of dinitrogen pentoxide, you need ___ grams of oxygen available.

__ N2 + __ O2 ⟶__ N2O5

4. Benzene is an organic solvent that releases a lot of energy when it is burned. Burning 0.103 moles of benzene will release ___ grams of carbon dioxide.

__ C6H6 + __ O2 ⟶ __ CO2 + __ H2O

The earth's moon is unusually large. two popular theories of the moon's origin include the "sister world" hypothesis, which states that the moon formed from the same materials as the earth, near enough to the earth that they fell into orbit around each other. a second theory is the "capture" hypothesis, in which the moon formed elsewhere in the solar system, and the earth's gravity pulled it into its orbit. studies of what the moon is made of indicate that some of its materials had to come from the earth or from the same area of the solar system where the earth had formed. at the same time, the moon does not contain much of the material that makes up the earth's core, so the moon could not have formed from the same materials as the earth. how do the two facts above affect the described theories of the moon's origin? a. they show that scientists will never agree on where the moon came from. b. they show that more experiments on moon formation need to be done. c. they show that no theory accounts for the existence of the moon. d. they show that neither theory is complete and entirely correct.

Identify and describe the three ways that mutations affect organisms.

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
