So just balance the eqn and take the numbers infront of it
take the unknown (the one that the qn is asking for) and ratio it with the known variable
and then put in the mol that you know for the known variable and just do math to get the answer for the unknown
Answer:
Electronegativity is the measure of a tendency of an atom to attract the bonding pairs of electrons.
Answer:
I guess number three (3) Is wrong
In chemistry, there is a common note that says, "Like dissolves like".
This pertains to the concept that polar substances can dissolve only other polar substances. Also, nonpolar substances are also only able to dissolve nonpolar substances.
Polarity of the substance depends primarily on the type of bond and the difference in electronegativity.
Water is a polar substance while vegetable oil is not. From the concept presented above, it may be concluded that water will not be able to dissolve the vegetable oil and the assumption is logical.
Answer:
Confusion is eliminated when the correct measurement is applied
Explanation:
A measurement standard is often described as the reference to which other measurements are judged or based on. Most times, measurement standard are used to determine how accurate an experimental measurement is.
A measurement standard may not eliminate confusion when the correct measurement is applied. If the scientist does not agree with the measurement standard being used, then problem will set in.
