A 18.77 g sample of a compound contains 5.99 g of potassium, K, 5.43 g of chlorine, Cl, and oxygen, O. Calculate the empirical f
evablogger [386]

The empirical formula of the compound is KClO₃.

<h3>Empirical formula </h3>

This is the simplest structural formula a compound can have.

The given mass of the elements;

potassium, K = 5.99 g

chlorine, Cl = 5.43 g

oxygen, O = 18.77 g - (5.99 + 5.43)g = 7.35 g

The empirical formula of the compound is calculated as follows;

K: \ \ \frac{5.99}{39} = 0.15 \\\\Cl: \ \ \frac{5.43}{35.5} = 0.15\\\\O: \ \ \frac{7.35}{16} = 0.46

<em>Divide through by the smallest fraction;</em>

K: \ \frac{0.15}{0.15} = 1\\\\Cl: \ \frac{0.15}{0.15} =1 \\\\O: \ \frac{0.46}{0.15} = 3

empirical formula = KClO₃

How does an atom of one element differ from the atom of another element?
Temka [501]

Explanation:

The atoms of one element differs from the atoms of other elements in terms of the number of protons they contain. This is often taken as the atomic number of such an atom.

  • The number of proton is the best indicator of the atom one is dealing with.
  • Based on this number, elements are categorized into distinct columns and rows on the periodic table.
  • The atomic number is the number of protons or positively charge particles in the atom.

II.

It is possible to change the identity of an atom. This is only possible by altering the atomic number of the atom.

Only nuclear reactions have this capability.

When an atom undergoes nuclear reaction that involves change in number of protons, transmutation occurs and a new atom forms.

In the Penny Lab that we ran, what is the independent variable? Question 1 options: the soap the number of water drops the penny
motikmotik

Answer:

I'd say it's the number of water drops.

Explanation:

The number of water drops is what you're controlling or purposely controlling and that answer choice makes the most sense out of the other answer choices. So I'd say it's "The Number of Water Drops."
