Explanation:
Cuttings can be made from any part of the plant. Most frequently, however, either a stem or leaf is used. A stem cutting includes a piece of stem plus any attached leaves or buds. Thus, the stem cutting only needs to form new roots to be a complete, independent plant.
The volume of phosphoric acid is mathematically given as
X= 75 mL of H3PO4
<h3>What is the volume of H2PO4 required?</h3>
Question Parameters:
Milliliters of 0.750 M H2PO4 are required to react with 250. mL of 0.150 M Ba(OH)2
Generally, the equation for the banlanced Chemical Reaction is mathematically given as
2 H3PO4 + 3 Ba(OH)2 ------> Ba3(PO4)2 + 6H2O
Therefore
The volume of phosphoric acid=
The volume of phosphoric acid=0.075 L of H3PO4
In conclusion, the volume of H2PO4 in mL is
The volume of phosphoric acid=75 mL of H3PO4
