Answer:
2.08moles
Explanation:
Given parameters:
Volume of solution = 800mL = 0.8L
Molarity = 2.6M
Unknown:
Number of moles of sugar in the solution = ?
Solution:
We need to understand the relationship between number of moles, volume and molarity of a solution.
The molarity of a solution is the number of moles of solute of a substance dissolved in a given solvent.
Molarity =
Number of moles of solute = molarity x volume of solution
Now input the parameters and solve;
Number of mole of solute = 2.6 x 0.8 = 2.08moles
The number of moles of sugar is 2.08moles
Answer:
B) ethers
Explanation:
The functional group of an organic compound defines its specificity. The functional group is responsible for the chemical behavior of an organic compound. For example, alkenes are known to have a carbon-carbon double bond (C=C) functional group.
Likewise, organic compounds known as ETHERS are known to possess an ethoxy functional group i.e. oxygen atom bonded to two alkyl groups (R- OR; where R is an alkyl group). Members of ether functional group includes dimethyl ether (CH3-O-CH3), diethyl ether (C2H5-O-C2H5).
Answer:
Geothermal energy is heat derived within the sub-surface of the earth. Water and/or steam carry the geothermal energy to the Earth's surface. Depending on its characteristics, geothermal energy can be used for heating and cooling purposes or be harnessed to generate clean electricity.
