What are " of the following"?
The mass of A needed in a mixture : 15.625 g
<h3>Further explanation</h3>
Given
A mixture of A and B
Ratio A : B = 1 : 8
mass b = 125 g
Required
The mass of A
Solution
Proust states <em>the Comparative Law</em> that compounds are formed from elements with the same Mass Comparison so that compounds have a constant composition of elements
Mass of A (from the mass of B):
= 1/8 x 125 g
= 15.625 g
The polarity of the molecules determines the forces of attraction between the molecules in the liquid state. Polar molecules are attracted by the opposite charge effect (the positive end of one molecule is attracted to the negative end of another molecule. Molecules have different degrees of polarity as determined by the functional group present.
<span>Principle: The greater the forces of attraction the higher the boiling point or the greater the polarity the higher the boiling point.</span>
Either air pressure or gravity. I would say its gravity because of the force of two object attracting each other.
Answer:The energy of the photon is this light is .
Explanation:
Wavelength of the electromagnetic radiation = 745 nm =
Energy of the photon will be given by Plank's equation:
The energy of the photon is this light is .
