Explanation:
Answer:
b. oxygen side being slightly negative and the hydrogen side being slightly positive.
Explanation:
The water molecule is a polar molecule, that is to say that its distribution of electronic density is different throughout the molecule.
In this way, in the water molecule there is a negative partial charge towards the oxygen atom and a positive partial charge towards the hydrogen atom.
This polar characteristic of the water molecule allows ions and other molecules to exhibit water solubility and is widely used in chemical reactions.
An ion is an atom that has lost or gained an electron so the relation ship you would see would be a negative or a positive one depending on if it gained or lost an electron.<span />
Answer:
Length of a rectangle whose width is 4 inches is
<u>6 inches</u>
Explanation:
Ratio of length to its width is 3 to 2
Let length = L
Let Width = B
L: B = 3 : 2 (given)

Width ,B = 4
Insert B in above equation


cross multiply,

L = 6 inches
Conversion(if required) ,
1 inch = 2.54 cm
6 inch = 2.54 (6)
L = 15.24 cm
