What is an easy way to define an ion?

An ion is any atom or group of atoms that has one or more electrical charges that are both beneficial and harmful. Ions have either a positive or negative charge, called cations or anions.

Where do ions come from?

Ions are produced when an atom's both electrons and protons are not balanced. As a result, an atom with an either positive or negative voltage that has already accumulated or lost three maybe more elements is referred to as an ion. Ionization is the process of protons moving between molecules and atoms.

Determine the empirical formula of each of the following compounds from the percent composition: a. 7.8% carbon and 92.2% chlorine b. 10.0% C c. 0.80% H, 89.1% Cl

Answers

The empirical formula of a compound with 7.8% carbon and 92.2% chlorine is CCl₄ and that of a compound with 10.0% C, 0.80% H and 89.1% Cl is CHCl₃.

In order to determine the empirical formula of the compounds, we have to divide the percentage by mass of each of the elements by their relative atomic masses and then divide them through the lowest ratio.

Carbon = 7.8%

7.8/12 = 0.65

Chlorine = 92.2%

92.2 / 35.5 = 2.59

Dividing by the lowest ratio,

Carbon  = 0.65/0.65 = 1

Chlorine = 2.59/0.65 = 3.98 ≅ 4

So the empirical formula is CCl₄.

Hydrogen = 0.80%

0.80/1 = 0.80

Chlorine = 89.1%

89.1/35.5 = 2.50

Carbon = 10.0%

10/12 = 0.83

Dividing by the lowest ratio,

Hydrogen = 0.80/0.80 = 1

Carbon = 0.83/0.80 = 1.03  ≅ 1

Chlorine = 2.50/0.80 = 3.1  ≅ 3

So the empirical formula is CHCl₃

which of the following would decrease the rate of a chemical reaction? adding more reactants stirring the reaction more vigorously squeezing the reactants into a smaller volume increasing the temperature raising the activation energy

Answers

Raising the activation energy would decrease the rate of a chemical reaction.

The rate of a chemical reaction refers to the speed at which the reactants are converted into products. There are several factors that can affect the rate of a chemical reaction, including the concentration of reactants, temperature, and the presence of catalysts or inhibitors.

Adding more reactants would generally increase the rate of a chemical reaction, as there would be more particles present to collide and react. Stirring the reaction more vigorously would also increase the rate of the reaction, as it would increase the chances of successful collisions between reactant particles. Squeezing the reactants into a smaller volume would also increase the rate of the reaction, as it would increase the concentration of reactants and the chances of successful collisions.

On the other hand, increasing the temperature would generally increase the rate of a chemical reaction, as it would increase the kinetic energy of the reactant particles and increase the chances of successful collisions.

However, raising the activation energy would decrease the rate of a chemical reaction, as it would require more energy for the reactant particles to overcome the activation energy barrier and undergo a successful reaction. Activation energy is the energy required to start a chemical reaction.

The mass of a substance can be calculated from the density by using the following expression;

Density = mass ÷ volume

According to this question, the dimensions of gold is given as 10.0 in x 4.00 in x 3.00 in. The density of gold is 19.3 g/cm³.

Volume of gold = 10 × 4 × 3 = 120in³

120in³ is equivalent to 1966.45cm³

Answers

Water is the most abundant atom is a false statement.

Water molecule is composed of two hydrogen atoms and one oxygen atom. Water is necessary for the survival of living organisms. Water is polar because the oxygen atom in water has a higher electronegativity than the hydrogen atoms, resulting in a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms.

Water stabilizes temperature because it has a high heat capacity, meaning it can absorb or release a large amount of heat without experiencing a significant change in temperature.
