In subtractive color mixing, like with ink on paper, when all three primary colors are combined the result is?
Maslowich

Subtractive colors mixing with all three primaries will result in black.

<h3>How are the 3 primary subtractive colors combined?</h3>

Adding all three subtractive primary color filters together will absorb all the colors of the white light spectrum as appeared below. Each filter (or pigment) absorbs its harmonizing color and transmits (diffusely reflects) the others.

Primary colors union of these three results in white. The subtractive primary colors are related to the subtraction of light: cyan, magenta, and yellow, the colors used in four-color printing, the union of these results in black.

So we can conclude that the usually used subtractive primary colors are cyan, magenta, and yellow, and if you overlap all three in a successful equal mixture.

In the water molecule, the H-O-H bond angle is 105º. Which distribution of electrons around the central atom provides the best e
masha68 [24]

Answer:

The correct option is: 2 shared pairs, 2 lone pairs

Explanation:

Water is an inorganic molecule that is composed of one central oxygen atom and two hydrogen atoms bonded by covalent bonds. The molecular formula of water is H₂O and the bond angle is 109.47°.

The <em>oxygen is sp³ hybridized</em> and there are<em> two bond (or shared) pairs and two lone pairs </em>of electrons in a water molecule. The<em> structure of H₂O is bent </em>due to the <u>repulsive forces between the lone pairs of electrons</u>.

<em>Due to these repulsive forces, the H-O-H bond angle decreases from 109.47°, which is the ideal bond angle to 104.45°.</em>
