Answer:

the octet rule is a chemical rule of thumb that reflects the observation that main group elements and bonds and such a way that each has a electrons in its valence shell giving the same electronic configuration as noble gas

How many moles of hydrogen are required to react with 4.6 x 10 22 molecules of nitrogen?
V125BC [204]

Answer: 6 moles

Take a look at the balanced chemical equation for this synthesis reaction

N 2(g] + 3 H 2(g] → 2 NH 3(g]

Notice that you have a  1:3  mole ratio between nitrogen gas and hydrogen gas. This means that, regardless of how many moles of nitrogen gas you have, the reaction will always consume twice as many moles of hydrogen gas.

So, if you have  2 moles of nitrogen taking part in the reaction, you will need

2 moles N 2 ⋅ 3 moles H 2 /1 mole N 2 = 6 moles H 2

if i add water to 100ml of a 0.15 m naoh solution until the final volume is 150 ml,what will the molarity of the diluted solutio
Katena32 [7]

Answer:

0.1 mol×L

Explanation:

Concentration= MOLES of SOLUTE / Volume of SOLUTION

So all we need to is to calculate the one quantity; Volume of SOLUTION has been specified to be 150 ml

So, MOLES of SOLUTE

x 100 x 10-L = ??mol; this was our starting solution.

And final CONCENTRATION=

0.15 . mol. 5 x 100 x 10-3L/

= 0.15 mol · L-1 150 x 10 3

=0.1 mol · L

Why does oxygen have a smaller atom size than nitrogen?
Lunna [17]

Answer:

The eight protons in oxygen atom's nucleus will exert more force than nitrogen's seven electrons. Also, oxygen has same number of shells as nitrogen. Thus electrons in oxygen atom will be closer to nucleus than in the case of nitrogen. When electrons are closer it means atomic radius is smaller.

Hope this helps! :)
