Answer:
Producing 300 L of ethanol from potatoes
Explanation:
From the diagram, one liter of ethanol production from sugar cane requires 2000 liters of water. Hence, in order to produce 100 L of ethanol from sugar cane, 2000 x 100 = 200,000 L of water.
1000 liters of water is needed to produce 1 liter of ethanol from sugar beet. Hence, 200 x 1000 = 200,000 L of water will be needed to produce 200 liters of ethanol.
1000 liters of water is also required to produce 1 liter of ethanol from potatoes, hence, 300 x 1000 = 300,000 L of water would be required to produce 300 L of ethanol from the same material
About 500 liters of water is required to produce 1 liter of ethanol from corn, hence, 400 x 500 = 200,000 L of water would be needed to produce 400 L of ethanol from corn.
<u>In conclusion, producing 300 L of ethanol from potatoes would require using the most water among all the options.</u>
You can use a drill. I dont see why you would need much more.
The error in her thinking is that oxygen has has six electrons and a negative charge is acquired by nitrogen when it gains two electrons.
Oxygen is a member of group 16. The elements in group 16 has six valence electrons. This means that they need an extra two electrons to complete their octet.
If an atom gains two electrons, it will have a charge of -2 and not +2, a positive charge means that the atom lost electrons. Nonmetals like oxygen do not loose electrons rather they gain electrons.

Answer:
v₁ = 5 m/s
Explanation:
We can use the law of conservation of momentum here:
where,
m₁ = m₂ = m = mass of each disk
u₁ = initial speed of yellow disk = 0 m/s
u₂ = initial speed of orange disk = 5 m/s
v₁ = final speed of yellow disk = ?
v₂ = final speed of orange disk = 0 m/s
Therefore,
<u>v₁ = 5 m/s</u>
