More dense substances will ... A. float above less dense substances
B. sink below less dense substances

B

The light object will not be able to handle the heavy object. The answer to the question is option B.

B) sink below less dense substances

heavy will fall over light.

d.) circle motion requires a force to give it a centripetal acceleration.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
