The chemical equation that you need is:

2KF(s)\ \to\ 2K(s) + F_2(g)

Explanation:

An equation will be balanced when there are equal number of atoms on both reactant and product side.

And a reaction in which a compound dissociates to give two products is known as a decomposition reaction.

For example, 2KF(s) \rightarrow 2K(s) + F_{2}(g)

This reaction equation represents decomposition of solid potassium fluoride into solid potassium and fluorine gas. Also, there are equal number of atoms on both reactant and product side so, the equation is balanced.

A block of aluminum occupies a volume of 15.0 ML and weighs 40.5 gallons what is the density
svlad2 [7]

Hello!

I'm going to have to infer that you meant "grams" and not "gallons" :-)

Anyways, to find the density, you need to the divide mass over volume (d = m/V).

Since we are given the volume being 15.0 mL, and the weight being 40.5 grams, we can find the density of the aluminum block.

40.5 grams / 15.0 mL = 2.7 g/mL

Therefore, the density of the aluminum block is 2.7 grams per milliliter.

Using a chemical equation to find moles of product from moles of reactant
kumpel [21]

Answer:

0.86 moles H₂O

Explanation:

To solve this problem, it is important to first determine the balanced chemical equation. The balanced equation is necessary as it will provide the mole-to-mole ratio needed to convert between moles O₂ and moles H₂O.

The unbalanced equation:

C₈H₁₈ (l) + O₂ (g) ---> CO₂ (g) + H₂O (g)

<u>Reactants:</u> 8 carbon, 18 hydrogen, 2 oxygen

<u>Products:</u> 1 carbon, 2 hydrogen, 3 oxygen

As you can see, the equation is not balanced because there are unequal amounts of each element on both sides. Balancing the equation is a matter of guessing-and-checking to see which combination of coefficients work.

The balanced equation:

2 C₈H₁₈ (l) + 25 O₂ (g) ---> 16 CO₂ (g) + 18 H₂O (g)

<u>Reactants:</u> 16 carbon, 36 hydrogen, 50 oxygen

<u>Products:</u> 16 carbon, 36 hydrogen, 50 oxygen

Now that the equation is balanced, we can use the coefficients of O₂ and H₂O to construct our mole-to-mole ratio and perform our conversion. The final answer should have 2 sig figs to match the given value (1.2 moles). The state of matter is most likely not necessary to include in your final answer.

1.2 moles O₂          18 moles H₂O
---------------------  x  -----------------------  =  0.86 moles H₂O
                                25 moles O₂
