Answer:
i added this table for some help
Explanation:
here are some examples
<u>metals:</u>They are hard and shiny, strong, and easy to shape. They are used for many industrial purposes. This group includes iron, gold, silver, chromium, nickel, and copper, some of which are also noble metals.
<u>non-metals:</u>a chemical element (as boron, carbon, or nitrogen) that lacks the characteristics of a metal and that is able to form anions, acidic oxides, acids, and stable compounds with hydrogen.
<u>metalloids:</u>Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. Metalloids have mixed properties which are difficult to characterize.
If you have a magnesium for every oxygen, then you have to start with two magnesiums. So the balanced equation is 2 Mg + O2 2 MgO.
And
CaCO3———→CaO + CO2
I hope it helped!
Ok so this all boils down to Newton's second law
Force = mass X acceleration
so the force = 10 X 3 = 30N
Answer:
is a plot showing the change in ph of the solution in the conical flask as the reagent is added from the burette
Explanation:
like, the ph of the solution at equivalence point is dependent on the strenght of the acid and strenght of the base used in the titration
False, as oceans can act as carbon sinks along with forests.
