I can’t see the image, can you name some of the energy resources under this comment?
Answer : The correct option is, (A)
Explanation :
Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
As we are given that:
Rate of disappearing component A =
Rate of appearing component B =
Rate of appearing component C =
The general reaction is:
As per question the stoichiometry relation will be:
Now put the values of rate of following components, we get:
Thus, the stoichiometry relation is:
a : b : c = 2 : 1 : 3
Thus, the required equation will be:
Partial mass of C, 12*2 = 24
Partial mass of H, 1*5 = 5
Partial mass of N, 14
Partial mass of O, 16
Now, total molar mass would be 24+5+14+16 = 59
mass % of carbon = 24 * 100 / 59 = 40.67%
Step 1;write the equation for reaction
the equation for reaction is as follows
NaOH + H3PO4 ---> Na2 PO4 + H2o
then calculate the moles of H3PO4 used
that is 34.55 x1.500/1000= 0.052 moles
by use of mole ratio between NaOH to H3Po4 which is 1:1 the moles of NaOh= 0.052 moles
volume of NaOh is= moles of NaOH/ molarity
that is 0.052 /1.420=0.03662 L
in Ml = 0.03662 x1000=36.62 Ml
