Answer

B. a fruit falling from a tree

Explanation:

Take, for example, an apple tree. ... The tree uses this energy to build leaves and branches and fruit. When an apple falls from the tree to the ground, its energy of position (stored as gravitational potential energy) is converted to kinetic energy, the energy of motion, as it falls.

Determine the formula of chromic acid.

Katyanochek1 [597]

Answer: The formula of chromic acid is $H_2CrO_4$

Explanation:

We are given an ionic compound named as chromic acid. This acid is formed by the combination of hydrogen ion and chromate ion.

An acid is defined as the substance which releases hydrogen ion when dissolved in water.

Hydrogen is the 1st element of periodic table having electronic configuration of $1s^1$ .

This element will loose 1 electron to form $H^{+}$ ion.

Chromate ion is a polyatomic ion having chemical formula of $CrO_4^{2-}$

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

So, the chemical formula for the given compound is $H_2CrO_4$

Thus, the formula of chromic acid is $H_2CrO_4$

Anettt [7]

Answer:

A skeleton equation shows just the reactants and products whereas a balanced equation shows the relative amounts of, or proportion between, reactants and products.

Explanation:

The skeleton equation shows which reactants are being used and which products are being formed.

The reactants are shown on the left and the products are shown on the right side of the equations, separeted by an arrow.

For example, the skeleton equation to obtain water is:

H₂(g) + O₂(g) → H₂O (g)

From it you know that hydrogen and oxygen react to form water, yet you do not know in which ratio they do it.

Then, you balance the equation, adding the appropiate coefficients, to make the number of atoms of each kind on the reactant side equal to the number of the same kind of atoms on the product side.

This is, for the example of water, the number of hydrogen atoms on the left must equal the number of atoms of hygrogen on the right side, and the number of oxygen atoms of the left must equal the number of oxygen atoms on the right.

For the water example that is:

2H₂(g) + O₂(g) → 2H₂O (g)

Showing that 2 molecuies of hydrogen (or 4 atoms) react with 1 molecule of oxygen (or 2 atoms) to produce 2 molecules of water, and that proportion (relative amounts) will always be true for that reaction.
