If it is assumed that this reaction is taking place at STP (standard temperature and pressure) then one mole of gas occupies 22.4L 

<span>You can then calculate that 3.6L of Hydrogen contains 0.16mol </span>
<span>1mol/22.4L x 3.6L = 0.16mol </span>

<span>Every 2 moles of Hydrogen require 1 mole of oxygen to form water. Therefore half of the number of moles of oxygen are required. </span>
<span>0.16mol/2 = 0.08mol </span>

<span>Again, we know that at STP 1 mol occupies 22.4L </span>
<span>0.08mol x 22.4L/mol = 1.79L of O2 needed. </span>

<span>Also 3.6/2 = 1.8 All ideal gasses will occupy the same ammount of space at STP</span>

If 3.91 moles of H2 were used, how many moles of NH3 would be made?<br><br> HELP PLEASE ASAP
matrenka [14]

N + H2 → NH3

balance the equation

2N + 3H2 → 2NH3

3H2 → 2NH3

3 : 2

3.91 ÷ 3 = 1.303 mol

1.3 × 2 = 2.606 mol

How to find the density of a liquid given only volume and molecular weight?
aalyn [17]
If you’re given molecular weight, you know that density is mass/volume. You need to convert the molecular weight to volume. If you know what molecule it is, use the gram formula mass to convert it into grams.

Which property of table salt is also a property of other ionic compounds
Svet_ta [14]
Most likely it’s crystalline structure, which makes it small granules that are soluble in water. Most, if not all, ionic compounds are salts. And salts dissolve in water.

Hope that’s correct
