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

If a enzyme denatures, it slows down because:
• It begins to use a new substrate
• it gets bigger and can’t move
• it changes shape and the substrate won’t fit
• it become to small
Answer:
The answer would be "C" because when an enzyme denatures, it changes it shape so that the substrate won't fit anymore. On a side note, when an enzyme is placed in an environment out of its pH or tempertaure range, it can denature.

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.

Logan heads out to the beach to examine the animal. Sure enough, the net has been wound tight
around one of the dolphin's fins and looks to have cut off the circulation, causing possible tissue
damage. Logan wants to get the dolphin back to the aquarium to try to treat it. Given the type of
animal he is about to transport, which precautions would Logan MOST likely take so that the dolphin
makes it to the center alive?
A.) Logan would make sure that the dolphin is kept warm because it gets its temperature from its surroundings.
B.) Logan will want to make sure he takes another dolphin with him to keep the first one calm during
transportation
C.) Logan will want to make sure the dolphin's skin stays moist by keeping it in water while transporting.
D.) The dolphin will need to be anesthetized during transport so that it does not bite or hurt any handlers.
Baecaise dolphins are aquatic animals, Logan will want to make sure the dolphin's skin stays moist by keeping it in water while transporting
