empirical formula = when the percentage compositions by mass of elements in a compound are divided by their relative atomic masses.

from the obtained amount the smallest amount will divide all.

the answers can then be rounded off if in decimals or they can be multiplied by 2 if they have .5 decimals e.g 2.5 , 7.5 , etc.

solution: HYDROGEN    CARBON      OXYGEN

                2/1                      74/12               24/16

                  2                         6.167                 1.5

                  2 / 1.5                  6.167 / 1.5           1.5 / 1.5

                  1.333                        4.111                   1

                      1                              4                        1


answer :     C4OH

When carbon is burned in air, it reacts with oxygen to form carbon dioxide. When 27.6 g of carbon were burned in the presence of
In-s [12.5K]

Answer:

The answer to your question is: 101.2 g of CO2

Explanation:

C = 27.6 g

O₂ = 86.5 g   remained 12.9 g

O₂ that reacted = 86.5 - 12.9 = 73.6 g

                     C     + O₂      ⇒        CO₂      The equation is balanced

                    27.6    73.6                 ?

MW               12        32                  44

Rule of three

                        12 g of C------------------  44 g  CO2

                       27.6 g C  ------------------    x

                  x = 27.6(44)/12 = 101.2 g of CO2

                       32 g of O2 ---------------    44 g of CO2

                        73.6 g of O2 ------------      x

                  x = 73.6(44)/32 = 101.2 g of CO2

In terms of valence electrons, explain why metals form positive ions.
diamong [38]

Answer:

Explanation:

Metal elements form positively charged ions called cations because they are located on the left side of the periodic table These elements all have valence electrons in an s orbital. These electrons are relatively easy for the atom to lose to achieve a stable octet of electrons in its outermost energy shell.
