Answer A B C and D please for my chemistry hw
r-ruslan [8.4K]

<u>Answer:</u> The equations are provided below.

<u>Explanation:</u>

Skeleton equations are defined as the equations which simply indicate the molecules that are involved in a chemical reaction. These equations are unbalanced equations.

Balanced equations are defined as the chemical equation in which number of individual atoms on the reactant side must be equal to the number of individual atoms on the product side.

  • For A:

Water decomposes in the direct current to form hydrogen and oxygen.

Skeleton Equation: H_2O(l)\rightarrow H_2(g)+O_2(g)

Balanced Equation: 2H_2O(l)\rightarrow 2H_2(g)+O_2(g)

  • For B:

Mercury (II) oxide decomposes in heat to form mercury, oxygen.

Skeleton Equation: HgO(s)\rightarrow Hg+O_2

Balanced Equation: 2HgO(s)\rightarrow 2Hg+O_2

  • For C:

Calcium carbonate when heated forms calcium oxide and carbon dioxide.

Skeleton Equation: CaCO_3(s)\rightarrow CaO(s)+CO_2(g)

Balanced Equation: CaCO_3(s)\rightarrow CaO(s)+CO_2(g)

  • For D:

Group 2 hydroxides, when heated forms oxide and water vapor.

Skeleton Equation: Ca(OH)_2\rightarrow CaO+H_2O

Balanced Equation: Ca(OH)_2\rightarrow CaO+H_2O

raketka [301]

Many of the actual chemicals in flower petals that give them their different colors are called anthocyanins. These are water-soluble compounds that belong to a bigger class of chemicals known as flavonoids. Anthocyanins are responsible for creating the colors blue, red, pink, and purple in flowers.

If a molecule has an empirical formula of C2H2O and a molecular mass of 84.0 g/mol, what is the molecular formula?
lord [1]

Answer:

=C₄H₄O₂

Explanation:

Given the empirical formula of a molecule, the he the quotient of the molecular mas and and the empirical mass=constant.

84.0 g/mol/mass of(C₂H₂O)=constant

=84/(12×2+1×2×16)

=84/42

=2

Therefore, the molecular formula is (C₂H₂O)₂=C₄H₄O₂
