Answer:
E.
Explanation:
Look at change in concentration over time...is it increasing or decreasing? It is increasing right as you can see because it starts at 0 then increases and plataeus. What increases in a reaction, reactant or product? Products increase right cuz your reactants react with each other to make prodcuts.
At start of reaction you have no products (zero) thus this graph starts at 0. At end you have alot of product thus over time the concentration of product increases.
ABC are reactants their concentration should decrease over time
DE are products, they should increase as reaction goes on.
I believe that the answer is Oxygen. Hope this helps. :)
The stored energy of an object is kinetic energy
694,563,239 rounded to the nearest thousand is 694,563.
It's because the first digit from the right is for ones, second for tens, third for hundreds and fourth for thousands and that's the one that we should take a closer look at. You can round it either to 3 or 4, depends on the digit of hundreds. In this case 3239 is clearly closer to 3000 than 4000, that's why we round it to 694,563, not 694,564.
