A sample of propane, C3Hg, contains 14.4 moles of carbon atoms. How many total moles of atoms does
Leona [35]

Answer:

43.2 mol C

115 mol H

158 mol of atoms

Explanation:

Step 1: Given data

Moles of C₃H₈: 14.4 mol

Step 2: Calculate the number of moles of C

The molar ratio of C₃H₈ to C is 1:3. The moles of C are 3/1 × 14.4 mol = 43.2 mol.

Step 3: Calculate the number of moles of H

The molar ratio of C₃H₈ to H is 1:(. The moles of H are 8/1 × 14.4 mol = 115 mol.

Step 4: Calculate the total number of moles of atoms

n = nC + nH = 43.2 mol + 115 mol = 158 mol

In salt, what is the nature of the bond between sodium and chlorine? in salt, what is the nature of the bond between sodium and
kifflom [539]

A chemical bond that involves the transfer of electrons from a metal to a nonmetal and thus forms ions and the atoms in the molecule are attracted towards each other through electrostatic force of attraction are said be ionic bond. In short, the bond formed between the two oppositely charged ions.

In salt, the compound formed between sodium and chlorine is sodium chloride having molecular formula NaCl where sodium is a metal and chlorine is the non-metal. The formation of the compound takes place by transfer of an electron from sodium thus forming a cation of formula Na^{+} to chlorine which gains electron and thus results in an anion formation having formula Cl^{-}. The force of attraction between these oppositely charged ions that helds them together and results in formation of NaCl compound is electrostatic force of attraction.

Hence in salt, the nature of bond between sodium and chlorine is ionic.
