Valentin [98]2 years ago
4 0

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.

V 2 O 5 + Cl 2  VOCl 3 + O 2
rosijanka [135]

Answer: 3.5 moles V2O5

Explanation: First balance the chemical equation to find the stoichiometric factor between VOCl3 and V2O5

2 V2O5 + 6 Cl2 => 4 VOCl3 + 7 O2

So the mole to mole ratio is 2 moles V2O5 to 4 moles of VOCl3

Solution

7 moles VOCl3 x 2 moles V2O5 / 4 moles VOCl3 = 3.5 moles V2O5
