Ionic bonds are forces that hold together electrostatic forces of attractions between oppositely charged ions. Ionic bonds have an electronegativity difference greater than or equal to 2. Covalent bonds have an electronegativity difference that is less than 2.
Answer:
Electrolysis of water is the process of using electricity to decompose water into oxygen and hydrogen gas. Hydrogen gas released in this way can be used as hydrogen fuel, or remixed with the oxygen to create oxyhydrogen gas, which is used in welding and other applications.Ordinarily, the freezing point of water and melting point is 0 °C or 32 °F. The temperature may be lower if supercooling occurs or if there are impurities present in the water which could cause freezing point depression to occur. Under certain conditions, water may remain a liquid as cold as -40 to -42°
Explanation:
Answer:
Blue dye spreads out quicker
Explanation:
This is because the dye gets spread out by water molecules. Warm water has faster moving water molecules than cold water.
Mass number = protons + neutrons
mass number = 5 + 7
mass number = 12
Answer:
1.2
Explanation:
Molarity = moles/volume
to find the moles, you must multiply both sides by volume
so, take 1.5 L * 0.80 M
this equals 1.2 :)
