Answer:
Ethanol
Explanation:
Solvent extraction is the process in which a compound transfers from one solvent to another owing to the difference in solubility or distribution coefficient between these two solvents(Science Direct).
We have to remember that oxalic acid will be extracted better into a solvent in which it is more soluble. From the data given; oxalic acid is more soluble in ethanol than in ether.
This simply means that ethanol is a better solvent for extracting oxalic acid from water when compared to ether.
Answer:
Greater
Explanation:
The longer the handle, the greater the mechanical advantage and the greater the increase in force that is applied to the bolt.
Mechanical advantage is the rate at which force is multiplied.
- It simply compares the output force to the input force.
- M.A is the force increasing tendency of a tool.
- The longer the handle, the more the mechanical advantage and the lesser the applied force.
The answer is 37.5 moles
The explanation:
1- when we have the mass of SO3 in Kg so, first we have to convert it to grams:
mass = 3 * 1000 = 3000 g
2- we need to get the molar mass of SO3 :
molar mass of SO3 = 32 + (16*3)
= 80 g/mol
3- then we can use this formula to get number of moles:
moles = mass / molar mass
= 3000 g / 80 g/mol
= 37.5 moles
Answer:
we have two loops in our body in which blood circulates. One is oxygenated, meaning oxygen rich, and the other is deoxygenated, which means it has little to no oxygen, but a lot of carbon dioxide.
Answer:
In addition to aluminium, the main materials in duralumin are copper, manganese and magnesium.
