Answer:

B

Explanation:

When nitrogen and aluminum form an ionic bond, the formula of the ionic compound is AlN. Aluminum forms a cation Al⁺³ and nitrogen forms an anion N⁻³. When each cation of Al⁺³ combines with an anion of N⁻³, AlN or aluminum nitride is formed

Cloud [144]

Answer:  Assuming the question: 3.54 ml (3 sig figs)

Explanation:

I don't see a question, but will assume it is "What volume is needed to obtain 26.5 grams?

If so:

(26.5 g)/(7.48 ml) = 3.54 ml (3 sig figs)

A sample of a gas in a balloon has a volume of 2.22 L and temperature of 23.9 °C. Calculate the volume when the temperature is r
nignag [31]

Answer:

Volume = 4.28L

Explanation:

Charles's gas law relates the volume and temperature of a gas at constant pressure. This law says that at constant pressures if we raise the temperature of a gas it will expand and if we reduce the temperature the volume will decrease. The formula is as follows:

{\displaystyle {\frac {V_{1}}{T_{1}}}={\frac {V_{2}}{T_{2}}}}

So, the initial conditions are 2.22L and 23.9 °C ant the final conditions are 46.1 °C we replace them in the equation. And then we solve it.

{\displaystyle {\frac {2.22}{23.9}}={\frac {V_{2}}{46.1}}

{\displaystyle {\frac {2.22}{23.9}} {46.1}={V_{2}

{\displaystyle {4.28}={V_{2}

Pretend you are the size of an atom and you are observing a reaction between a potassium ion and a fluorine atom. Describe how a
Elena L [17]
Due to periodic trends potassium would lose its one valence electron to have a more stable electron configuration equivalent to that of argon, which is a noble gas with a full octet. Fluorine would gain one valence electron to get a full octet equivalent to that of neon. Since potassium lost an electron it now has a positive charge and since fluorine gained an electron it is now negative. Since both are more stable this way as a full octet they will no longer exchange electrons but the positive potassium and negative fluorine will pull towards each other strongly forming an ionic bond.
