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
This is called a life span.
Answer:
Non-renewable resources, such as coal and oil, are the primary source of power in the world, and they are used to power vehicles, factories, and homes. Although affordable, they can be harmful to the environment and are one of the notable contributors to global warming.

Answer:
B. SO2
Explanation:
An Ionic bond transfurs electrons and occurs with metals and nonmetals
Covalent is the sharing of electrons and occurs with nonmetals only.
Answer:
HI& HNO3= strong acid
H2CO3 &HF= weak acid
LiOH & Ba(OH)2= strong base
CH3NH2= weak base
NH4Cl = weak acid solution
Na3PO4 = weak base solution
Explanation:
HI& HNO3= strong acid because they can dissociate completely producing free Oxonium ions
H2CO3 &HF= weak acid because there dissociate partly in Solution
LiOH & Ba(OH)2= strong base because LiOH is a group one alkali which dissociate completely and Ba(OH)2 a group 2 alkali which dissociate completely as well
CH3NH2= weak base because in solution it dissociates partly forming NH4+ ion
NH4Cl = weak acid solution because it is a salt of strong acid and weak base
Na3PO4 = weak base solution
Because it's a salt of strong base and weak acid
