Mariulka [41]

Answer:

Name of the compound is Nitrogen triiodide.

Explanation:

According to the IUPAC rules, to naming of the compound the following formula can be applied.

Prefix + Name of first element + Base name element of second element + Suffix.

The given compound - NI_{3}

Name of first element- Nitrogen

Base name element of second element - Iodine

Suffix = 3 = tri

Here, iodine is in ionic form therefore, it becomes iodide. and then suffix will be added in front of the halogen.

Therefore, name of the compound will be  Nitrogen triiodide..

helium ballon is filled iwth a volume of 2.88 x 10 to the 3 power at 722 mmHg and 19C. When the ballon is released, it rises to
antiseptic1488 [7]

Answer:  The volume of the balloon is 4.58\times 10^3

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 722 mm Hg

P_2 = final pressure of gas = 339 mm Hg

V_1 = initial volume of gas = 2.88\times 10^3

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 19^oC=273+19=292K

T_2 = final temperature of gas = -55^oC=273-55=218K

Now put all the given values in the above equation, we get:

\frac{722\times 2.88\times 10^3}{292}=\frac{339\times V_2}{218}

V_2=4.58\times 10^3

Thus the volume of the balloon is 4.58\times 10^3
