The basic structural unit in ionic and molecular compounds has to be contrasted. Concept Introduction: Bonds are formed between the atoms and it is the force that holds the atom together. There are mainly two types of bonds and they are ionic bond and covalent bond. Ionic bonds are formed between different elements (metal and nonmetal). Ionic bonds are formed by giving and accepting valence electrons. Covalent bonds are formed between two nonmetals. They can be of same atoms or different atoms also. Covalent bonds are formed by sharing of valence electrons between two atoms.

Solution Summary: The author explains the basic structural unit in ionic and molecular compounds. Ionic bonds are formed by transfer of electrons from one atom to another.
Definition Definition Connection between particles in a compound. Chemical bonds are the forces that hold the particles of a compound together. The stability of a chemical compound greatly depends on the nature and strength of the chemical bonding present in it. As the strength of the chemical bonding increases the stability of the compound also increases.

Interpretation Introduction
Interpretation:
The basic structural unit in ionic and molecular compounds has to be contrasted.
Concept Introduction:
Bonds are formed between the atoms and it is the force that holds the atom together. There are mainly two types of bonds and they are ionic bond and covalent bond.
Ionic bonds are formed between different elements (metal and nonmetal). Ionic bonds are formed by giving and accepting valence electrons. Covalent bonds are formed between two nonmetals. They can be of same atoms or different atoms also. Covalent bonds are formed by sharing of valence electrons between two atoms.
Dr. Mendel asked his BIOL 260 class what their height was and what their
parent's heights were. He plotted that data in the graph below to determine if
height was a heritable trait.
A. Is height a heritable trait? If yes, what is the heritability value? (2 pts)
B. If the phenotypic variation is 30, what is the variation due to additive alleles?

Experiment:
Each team will be provided with 5g of a mixture of acetanilide and salicylic acid. You will divide it into three 1.5 g portions in separate 125 mL Erlenmeyer flasks savıng some for melting point analysis. Dissolve the mixture in each flask in ~60mL of DI water by heating to boiling on a hotplate. Take the flasks off the hotplate once you have a clear solution and let them stand on the bench top for 5 mins and then allow them to cool as described below.
Sample A-Let the first sample cool slowly to room temperature by letting it stand on your lab bench, with occasional stirring to promote crystallization.
Sample B-Cool the second sample 1n a tap-water bath to 10-15 °C
Sample C-Cool the third sample in an ice-bath to 0-2 °C
Results:
weight after recrystalization and melting point temp.
A=0.624g,102-115°
B=0.765g, 80-105°
C=1.135g, 77-108
What is the percent yield of A,B, and C.
