C. At some point, the land masses were connected to each other.

Explanation:

The fossils now exists far away from each other because at some point, the land masses were once connected to each other. Now, the land masses have drifted apart due to plate tectonics.

Alfred Wegener a scientist in 1912 first formulated the theory of continental drift. The theory suggests that present day land masses have moved to their present positions.

  • A more refined theory of plate tectonics is now in play today and it provides a better understanding to why we can find similar features across different continents.
  • The similar fossils must have formed together when the land masses were once joined together.
  • Noe that the land masses are separated, the fossils species are not separated.

Which has the higher percentage of aluminum, Al2O, or Al(NO3)3
Rzqust [24]

Al₂O  has a higher percentage of aluminium.

Explanation:

To solve this problem, we have to compare the molar mass of the aluminium in each compound to one another as percentage of the whole compound:

Molar mass of Al₂O = 2(27) + 16 = 70g/mol

Molar mass of Al(NO₃)₃ = 27 + 3[14 + 3(16)] = 213g/mol

Percentage by mass of Al in Al₂O = \frac{2x27}{70} x 100 = 77%

Percentage by mass of Al in  Al(NO₃)₃ = \frac{27}{213} x 100 = 12.7%

Al₂O  has a higher percentage of aluminium.

Help please ;( really don’t understand Chemistry would really appreciate it if can explain to me thank you!
Tanya [424]

Answer:

b)   O₂

d)   CH₄

Explanation:

In a chemical equation, the <u>reactants</u> are the substances that are written on the <u>left side</u>. The reactants react to produce the products. On the right side, the products are written.

The arrow => is used to separate the reactants from the products.

To the left of the arrow, you can see this written:

CH₄ + 2O₂

The plus sign + is used to separate each reactant.

In 2O₂ you can ignore the big 2 because it is a coefficient, which is written to balance the equation.

The reactants are CH₄ and O₂
