bogdanovich [222]

Answer:

Explanation:

The Key results in the Lab guide are results that justify the reasons to either accept or reject a hypothesis.

To summarize data related to findings in an experiments we make use of diagrams that shows the relationship between the different data.

Although the Lab guide in the question is missing a general answer within the scope of your question is provided above

Key results in an experiment are either milestone results leading to the final result of an experiment or results obtained that might not be part of the experiment but very important to the success of the experiments. therefore results that leads to the acceptance or rejection of a hypothesis in an experiment is a key result.   while

The best way to summarize data related to findings is the use of diagrams. ( graphical representation of the relationships between data contained in an experiment )

Hence we can conclude that use of diagrams is the best way to show the relationship between different data related to experimental findings while key results are results that justifies the acceptance of a hypothesis.

What principle do we use in writing the formula of an ionic compound such as NaCl or MgI2? How do we know that two iodide ions a
Savatey [412]

Answer:

We know based on the charges of each ion and the fact that they must always sum to 0

Explanation:

Na only has one outer electon to give so it is always +1

Mg has two outer electrons so it always gets +2

Halogens have one "missing" electron in their outer shell so they get a -1

For NaCl  (+1) + (-1) = 0

For MgI2 (+2) + 2(-1) = 0

What’s the Difference between attractive forces and ionic/covalent/metallic bonds
Deffense [45]

Answer:

Explanation:The main difference between ionic covalent and metallic bonds is their formation; ionic bonds form when one atom provides electrons to another atom whereas covalent bonds form when two atom shares their valence electrons and metallic bonds form when a variable number of atoms share a variable number of electrons in a metal lattice.
