What does covalent and ionic bond have to do with chemical bond?

krok68 [10]

Covalent and ionic bonds are two different types of chemical bonding. Covalent bonds involve the sharing of electrons between 2 atoms while ionic bonds involve the complete transferring of electrons from one atom to another. Covalent bonds usually form between two nonmetals while ionic bonds usually form between a metal and a nonmetal.
I hope this helps. Let me know if anything is unclear.

1. Classify each of the following as a homogeneous or heterogeneous substance.

Olegator [25]

a. iron ore - heterogeneous substance

(it contains a mixture of iron oxides)

b. quartz - homogeneous substance

(it is the crystalline silicon dioxide SiO₂, which is a very pure form of SiO₂)

c. granite - heterogeneous substance

(it as mixture of different oxides, mainly aluminium and silicon oxides)

d. energy drink - heterogeneous substance

(a mixture of water, sugar, carbon dioxide and different substances that may boost concentration, like caffeine)

e. oil-and-vinegar salad dressing - heterogeneous substance

(this salad dressing of oil and vinegar is composed of unsaturated triglycerides, acetic acid and water)

f. salt - homogeneous substance

(sodium chloride NaCl)

g. rainwater - homogeneous substance

(assuming the the atmosphere is clean, it is just pure water H₂O)

h. nitrogen - homogeneous substance

(it is the main component of air and it is a diatomic molecule N₂)

Draw the structure of the compound identified by the following simulated 1H and 13C NMR spectra. The molecular formula of the co

Luba_88 [7]

Answer: 4-allylanisole

Explanation: The doublets behind the 7 ppm belongs to the

para-substituted benzene ring. The three single-proton multi-plets around 5−6 ppm predicts that there has to be a single subsituted alkene group

A single plus a doublet around 3-4 ppm belongs to CH3 and CH2 Groups as they could be attached to the subsituted alkene group.

Moreover the interpretation of the NMR that there is no peak with a higher intensity for >180 ppm represents an absence of Carbonyl group.

The Predicted Number is attached from a chemical database along with their peaks information

Matter is made up of heat energy and ___________energy?

ella [17]

You’re correct, matter is made up of heat energy and chemical energy

all matter contains heat because it is the result of the movement of atoms, molecules, or ions in solids, liquids, and gases.

all matter also contains chemical energy. chemical energy is stored in the bonds of chemical compounds so atoms and molecules are held together by chemical energy

hope this helps :)
