I like this guy. My brother found out and sent him a note saying its from ME! It says that I like him and he marked no, but we are only in 8th grade so he could just be saying that. Anyway, since that day, he has been opening up to me. What do I do?

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
