Answer : The volume of the resulting solution will be 0.4999 L.
Explanation : As the two molar concentration of the
solution are given and one of the volume concentration needs to be found.
So, according to the formula :-
And here if we consider
as 0.1718 L moles and
as 0.3556 moles then we need to find
as
is given as 0.1222 moles.
Hence on solving the formula we get,
= (0.1718 X 0.3556) / 0.1222 = 0.4999 L
The statement is false as 85675 grams of nitrogen dioxide is produced instead of 20 grams.
Explanation:
Balance equation for the reaction:
2NO + 
⇒ 2N
Data given:
mass of nitrogen produced = 20 gram
mass of oxygen = 29.8 litres or 29800 grams
0xygen is the limiting reagent so,
number of moles of oxygen: (atomic mass of 1 mole 32 grams/mole
number of moles = 
putting the values in the equation:
= 
= 931.5 moles
1 mole of oxygen reacts to give 2 moles of NO2
931.5 moles of oxygen will give x moles
=
1862.5 moles of NO2 produced
in grams
mass = number of moles x atomic mass
mass = 1862.5 x 46.00
= 85675 grams
The statement is false as 85675 grams of nitrogen dioxide is produced instead of 20 grams as said in question.
Answer:
protons : 10
electron : 10
neutron : 10
Explanation:
Protons will usually be the same as the electrons when its a <u>Atom</u> (when its a ion or covalent bond or simple bond they will most likely be different)
the atomic number represents protons and electrons
the mass number - the atomic number = neutron
