"It is important to balance chemical equations because there must be an equal number of atoms on both sides of the equation to follow the Law of the Conservation of Mass"
Explanation:
Atomic number of Silicon..=14
Answer:
2.843 M
Explanation:
Molarity = moles / volume
<u>Milliliters to liters:</u>
500 mL <u>= .500 L</u>
<u>Grams to moles:</u>
MgO molar mass = 16.00 + 24.31 = 40.31 g/mol
57.3 g x 1 mol / 40.31 g = <u>1.421 mol</u>
<u>Molarity:</u>
1.421 mol / .500 L = 2.843 M
As the size of a star increases, luminosity increases. If you think about it, a larger star has more surface area. That increased surface area allows more light and energy to be given off. Temperature also affects a star's luminosity.
