How are ionic compounds named?<br><br>

Dimas [21]

Answer:

Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions.

Explanation:

For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion.

Which of these substances will conduct electricity? CuSO4(s) CuSO4(aq) C5H12(l) CO2(g)

lara31 [8.8K]

Answer:

CuSO4(aq)

Explanation:

The aqueous for of CuSO₄ is an electrolyte and it will conduct electricity.

CuSO₄ is an ionic substance and in solid state, it will not have the ability to conduct electricity.

In aqueous form, it will contain free mobile ions which serves as carriers of electric current.
In the solid state, the ions are arranged into a crystal lattice and will not conduct a current of electricity.
The remaining given compounds will not conduct electricity as they are non-polar and do not have free mobile electrons.

Which law relates to the ideal gas law?

professor190 [17]

<u>Answer:</u> The law that related the ideal gas law is $\frac{V_1}{n_1}=\frac{V_2}{n_2}$

<u>Explanation:</u>

There are 4 laws of gases:

<u>Boyle's Law:</u> This law states that pressure is inversely proportional to the volume of the gas at constant temperature.

Mathematically,

$P_1V_1=P_2V_2$

<u>Charles' Law:</u> This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

<u>Gay-Lussac Law:</u> This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

<u>Avogadro's Law:</u> This law states that volume is directly proportional to number of moles at constant temperature and pressure.

Mathematically,

$\frac{V_1}{n_1}=\frac{V_2}{n_2}$

Hence, the law that related the ideal gas law is $\frac{V_1}{n_1}=\frac{V_2}{n_2}$
