1. What is the law of conservation of mass? 2. How is the law of conservation of mass related to balancing equations?

3. What is a balanced chemical equation?

4. Balance the following combustion reaction, and draw a corresponding picture of the correct number of
particles.

C2​H4​ + O2​ → CO2​ + H2​O

5. I have ten moles of iron atoms in the reactant side of a reaction. Do I have enough information to determine
how many moles of iron atoms I will have following the reaction? If so, how many moles of iron atoms will I
have at the end of a reaction? If not, what else do I need to know?

6. I have three moles of Methane (CH4​) on the reactant side of the reaction. Do I have enough information to
determine how many moles of products I will have following a reaction? If not, what else do I need to know?

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

i don't know people like to fight everywhere rip.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
