How many molecules of nitrogen dioxide would form from 2 molecules of no?

2 molecules of nitrogen dioxide would form from 2 molecules of NO.

Explanation:

Data given:

molecule of NO given = 2

molecules of nitrogen dioxide formed = ?

Avagadro number = 6.022 X molecules

atomic mass of NO = 30 gram/mole

atomic mass of N = 46 grams/mole

balanced chemical reaction is given by:

2NO + ⇒ 2N

to convert the molecules into moles, we use the formula:

moles =

the number of moles are same in the reaction for both reactant and product which means that 2 moles of NO reacts to form 2 moles of NO2.

thus when moles remain same, number of molecules are also same.

1 molecule = one mole x Avagadro's number

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
