Imagine you are standing in a kitchen and then
ozzi

You would see mostly compounds because elements make compounds and with these elements making compounds you are most likely not going to see them and since your in the middle of the forest you won't see much mixtures as much as compounds since we create most mixtures. Hope this helps my dude ^^

Use the unbalanced equation NH3 + O2 = NO + H2O, what is the mole ratio between NH3 and NO
kirill115 [55]
<span>The first thing that needs to be done in order to answer the question above is to balance first the chemical equation by seeing to that the number of moles of a certain element on the reactant side is equal to the number of moles in the product side. 4NH3 + 5O2  4NO + 6H2O The mole fraction between the NH3 and NO is therefore 4:4 or 1:1.</span>

What volume of 3.00 M CH3COOH solution is needed to provide 0.220 mol of CH3COOH?
harkovskaia [24]

0.0733L of 3.00 M CH3COOH solution is needed to provide 0.220 mol of CH3COOH.

<u>Explanation</u>:

Molarity, M = moles of the molecule / Liter of solution

Therefore, we can work backwards to find the number of litres of solution, if we are given the number of moles

The values are a given as,

The molarity of the solution =3.00M

The final moles = 0.220 moles.

 0.220 mol CH3COOH ( 1L / 3.00 mol CH3COOH) = 0.220/3.00                          

                                                                                     =0.0733L of solution
