Light is made of particles and with help of them the particle theory of light explains the light. Newton concluded that light has frequency-like properties. According to this the particle theory of light supports the phenomena of light bending around objects. Albert Einstein conducted research on the photoelectric effect, in which electrons fly out of a metal surface exposed to light and <span>energy of the electrons (photoelectrons) that fly out of the metal does not change whether the light is weak or strong.</span>

12 = 3X X = <br> 7X = 57 X = <br> 11X = 27.7 X =

dybincka [34]

Answer:
1. $x=4$
2. $x=\frac{57}{7}$
3. $x=\frac{27.7}{11}$

Explanation:

Given the following questions:

$12=3x$
$7x=57$
$11x=27.7$

In order to find the answers to these questions, we have to recognize that in order to isolate the variable we need to divide on both sides.

Question one:
$12=3x$
$\frac{3x}{3} =\div3$
$12\div3=4$
$x=4$

Question two:
$7x=57$
$\frac{7x}{7} =\div7$
$57\div7=8.14285714=\frac{57}{7}$
$x=\frac{57}{7}$

Question three:
$11x=27.7$
$\frac{11x}{11} \div11$
$27.7\div11=2.51818182=\frac{27.7}{11}$
$x=\frac{27.7}{11}$

Hope this helps.

Aluminum has the electronic configuration 2,8,3. How many valence

Klio2033 [76]

Answer:

3 valence electrons

Explanation:

Because aluminum has three, that means three fluorines can bond. The make the formula AlF3, also known as aluminum trifluoride. Each of the fluorine atoms gets an electron to fill their shell, and the aluminum loses three, giving it a filled shell too (remember, aluminum has three extra electrons).
