In order to understand what is the limiting reactant is useful to convert the masses of reactants into moles. The molecular masses are:
Converting masses into moles:
In the reaction, 2 moles of
are necessary to react with 1 mol of
. Following this ratio:
We have only 0.5 mol of
, i.e, we don't have enough amount of salicylic acid, therefore, this is the limiting reactant.
The very top layer on earth gets the most leathering because the rain, sleet, snow, ect. Mostly hits that top surface...
The other layers in earth dont get that much weathering because, well.... Like i said, everything mainly happens on the top layer.
~Hope this helped, anymore questions please ask! :)
Protons and neutrons have similar mass. Electrons are smaller than a proton or a neutron. An atomic scientist was studying an atom and through experimentation found that the total negative charge of the area surrounding the nucleus is -9.
Hey there !
Given the reaction:
N2 + 3 H2 = 2 NH3
At constant pressure and temperature ,volume is proporcional to moles:
Theoretical moles of N2 and H2 => 1:3
Theoretical volume of N2 and H2 => 1:3
Experimental volume of N2 and H2 => 3.0 L : 4.0 L
0.75 : 1 = 2.25 : 3
Since N2 is in excess reactant , H2 is the limiting reactant
Therefore:
volume of NH3 is 2/3 * Volume of H2
= 2/3 * 4.0 = 2.66 L
Hope that helps!
