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
Answer:
HCl is reduced and is the oxidizing agent
Explanation:
Looking at the reaction shown in the question
Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)
HCl is reduced to H2. The oxidation number of hydrogen decreased from +1 to zero. While magnesium was oxidized. Its oxidation number increased from zero to +2.
Hence we can rightly say that HCl was the oxidizing agent since the oxidizing agent is reduced in a reaction and the reducing agent is oxidized in a reaction.

Answer:
On a roller coaster, energy changes from potential to kinetic energy and back again many times over the course of a ride. Kinetic energy is energy that an object has as a result of its motion. Potential energy is the energy an object has as a result of its position
