<span>Fluorine, chlorine, bromine, and iodine grouped together because they have the same chemical and physical properties. They are also called halogens and under Group 7</span>
It's one ratio per substance so say if you had N2 + 3H2 > 2NH3 (chemical equation for the synthesis of ammonia) just look at the number coefficients(for 3H2 the coefficient would be 3 and for 2NH3 the coefficient would be 2 and so on)So it would take 1mole of nitrogen to react with 3 moles of hydrogen In order to produce 2 moles of ammonia so there would be 6 ratios you could write comparing two substances at a time In a reaction involving 3 substances ^^; hope this helps somewhat ^^;
Answer:
Place two of them as reactants.
Explanation:
- We have the two steps of reactions:
1) N₂(g ) + O₂(g) → 2NO(g).
2) 2NO(g )+ O₂(g) → 2NO₂(g).
- Adding the two equation with cancelling the intermediate (NO), we get:
<em>N₂(g ) + 2O₂(g) → 2NO₂(g).</em>
<em></em>
NO is cancelled out because there is one in each equation in the products side in eq. 1 and in oriduct side in eq. 2.
<em>So, we place two of oxygen as reactants.</em>
