Answer:

In chemistry, there are three definitions in common use of the word base, known as Arrhenius bases, Brønsted bases and Lewis bases. All definitions agree that bases are substances which react with acids as ... A ...

Acids are species with pH less than 7, while bases those with pH greater than 7. ... Using Arrhenius' definition, acids are those that produce the hydrogen ion when dissolved in water ( ) while bases produce the hydroxide ion ( ). These ions, when in water, act as charge carriers and can hence conduct electricity.

Acid–base reactions require both an acid and a base. ... For example, according to the Arrhenius definition, the reaction of B If inorganic, determine whether the compound is acidic.

Answer:- $1.91*10^2^3Cl$ atoms.

Solution:- We have been given the grams of carbon tetrachloride and asked to calculate the number of atoms of chlorine. It is a three step conversion problem. In the first we convert the grams of carbon tetrachloride to moles of it. In second step we convert moles of carbon tetrachloride to moles of chlorine and in the third step we convert the moles of chlorine to atoms of chlorine.

For grams to mole conversion we need the molar mass of the compound. Molar mass of carbon tetrachloride is 153.82 grams per mol. If we look at the formula of carbon tetrachloride then four chlorine are present in it. It means 1 mol of carbon tetrachloride has four moles of chlorine. The calculations are as follows:

$12.2gCCl_4(\frac{1molCCl_4}{153.82gCCl_4})(\frac{4molCl}{1molCCl_4})(\frac{6.02*10^2^3Clatoms}{1molCl})$
