(d) Solid lithium nitride conducts electricity and is used in batteries. Why would you expect solid lithium nitride not to condu

guapka [62]

Answer:

Solid ionic compounds do not conduct electricity because the ions are held firmly in place. The ions cannot move to conduct the electric current. But when an ionic compound melts, the charged ions are free to move. Therefore, molten ionic compounds do conduct electricity.

A solution is prepared by mixing 0.3355 moles of NaNO3 (84.995 g mol-1) with 235.0 g of water (18.015 g mol-1). Its density is 1

Answer:

Molality = 1.428m

Explanation:

Molality, m, is an unit of concentration defined as the ratio between moles of solute and kg of solvent:

Molality: Moles solute / kg solvent.

In the problem, water is the solvent (Is the compound in the higher quantity) whereas NaNO₃ is the solute.

Moles of solute: 0.3355moles NaNO₃.

Kg solvent:

$235.0g\frac{1kg}{1000g} = 0.2350kg$

Thus, molality of the solution is:

Molality = 0.3355 moles NaNO₃ / 0.2350kg

<h3>Molality = 1.428m</h3>

How many moles of oxygen (O2) are present in 33. 6 L of the gas at 1 atm and 0°C? 1. 5 2 22. 4 32.

oee [108]

The number of moles of oxygen in the gas is 1.5 L.

The correct option is (A).

<h3>What are moles? </h3>

The mole is the International System of Units' foundation unit of material quantity.

Given,

The volume of gas is 33.6 L

Pressure is 1 atm.

Temperature is 0°C

Molar gas volume is 22.4 L

There is no temperature and pressure is 1 atm.

By formula of moles, volume is divided by molar mass

$\bold{\dfrac{33.6}{22.4 } =1.5\; mole}$

Thus, option A is correct. 1.5 L.
