Your answer is going to be A, because it was shoved harder, it will go faster
Answer:
Mass fraction = 0.08004
Mole fraction = 0.0377
Explanation:
Given, Mass of NaOH = 8.70 g
Mass of solution = 8.70 + 100 g = 108.70 g
= 0.08004
Molar mass of NaOH = 39.997 g/mol
The formula for the calculation of moles is shown below:
Thus,
Given, Mass of water = 100 g
Molar mass of water = 18.0153 g/mol
The formula for the calculation of moles is shown below:
Thus,
So, according to definition of mole fraction:
Answer:
Using Pauling's scale—C (2.55) and H (2.2)—the electronegativity difference between these two atoms is 0.35. ... Because of this small difference in electronegativities, the C−H bond is generally regarded as being non-polar. In structural formulas of molecules, the hydrogen atoms are often omitted
Well fingerprint are more versatile and easy to acquire than any other biometrics. They are accepted in a court of law and no two people (not even identical twins) have the same fingerprints, it is extremely easy for even the most accomplished criminals to leave incriminating fingerprints at the scene of a crime. Fingerprints are one of a kind.
