Covalent bonded atoms make up what

Chemistry
1 answer:
White raven [17]3 years ago
7 0
In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.

What is the density of a liquid if the volume is 25 mL and the mass is 20.0 g?
LenKa [72]

Answers:  

                   Density = 0.8 g/mol.        

Given data:

                   v = 25 ml

                    m = 20 g

                    δ = ?

Solution:

               Formula for calculating density is given as,

                Density = Mass / Volume    

                 putting values  

                 Density = 20.0 g / 25 ml

                  Density = 0.8 g/mol.

When 1 mole of bacl2 is dissolved in water it releases-8.67 kj/mil of energy. calculate h when 10.3 g of barium chloride is diss
dybincka [34]

An inorganic substance with the formula BaCl2 is barium chloride. It is one of the most popular barium salts that dissolve in water. Like the majority of other water-soluble barium salts, it is white, extremely hazardous, and gives flames a yellow-green tint.

When 1 mole of bacl2 is dissolved in water it releases-8.67 kj/mil of energy. calculate h when 10.3 g of barium chloride is dissolved to make a 1.00 l solution

In water, barium chloride is very soluble (as is the case with most ionic salts). In its dissolved condition, it is known to split into barium cations and chloride anions.

Let's first determine the total amount of CL- ions.

=> When HCl dissociates, one mol will produce H+ and one mol will produce CL-. Thus, . 2 moles yields. 2 mol CL-

=> One mole of Bacl2 will dissociate into one mole of Ba2+ and two moles of CL-. Therefore, 0.1 mol will result. two moles CL-

Hence, there are mols of CL- in total.

2+.2 = .4

=> Molarity:

Total moles of solute divided by liters of solution gives the molarity, M.

= .4/.5 = 0.8 M

As a result, 0.8 M is the molarity of CL- in solution.
