m ) M How many milliliters of 0.750 M H2PO4 are required to react with 250. mL of 0.150 M Ba(OH)2 if the products are barium phosphate and water?
The volume of phosphoric acid is mathematically given as
X= 75 mL of H3PO4
What is the volume of H2PO4 required?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=[tex]\frac{3*2*250*150*3*1}{1*2*750}[/tex]
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

What role do surface properties play in determining the lifespan of a flu virus?
Answer:
Surface properties have less to do with virus lifespan than does the type of virus. Viruses tend to remain viable for longer on non-porous materials than on porous ones. Viruses tend to remain viable longer on surfaces with low moisture content.
Explanation:
The surface properties in the lifespan of a flu virus are associated with the fact that viruses tend to remain viable for longer on non-porous materials than on porous ones.
Influenza (flu) viruses are contagious viral infections capable of affecting the airways of the lungs.It has been shown that flu viruses survive on human tissues for only 15 min because of their surface properties.Moreover, it has been shown that these viruses cannot survive on non-porous metal/plastic surfaces by more than 9 hours.In conclusion, the surface properties in the lifespan of a flu virus are associated with the fact that viruses tend to remain viable for longer on non-porous materials than on porous ones.
