Answer:

The bonds prevent ions from moving throughout the crystal, so a solid ionic compound is a poor conductor.

Explanation:

Ionic bonds are those bonds that form between the ions of molecules. It is formed as a result of electrostatic attraction between the molecules or compounds. The ionic bonds that forms between ionic compounds are responsible for certain properties exhibited by them.

Ionic bonds hold the molecules of ionic compounds so tightly that it prevent ions from moving throughout the crystal, hence, a solid ionic compound is a poor conductor of heat and electricity.

A sample of neon gas occupies 4.5 L of gas at 1.63 atm. What will be the volume if the pressure changes to 2.4 atm

Alenkasestr [34]

Answer:

$\boxed {\boxed {\sf 3.1 \ liters}}$

Explanation:

This question asks us to find the new volume if the pressure changes. Therefore, we use Boyle's Law, which states that pressure and the volume of the gas are inversely proportional. The formula is:

$P_1V_1=P_2V_2$

We know that the original sample of gas occupies 4.5 liters at a pressure of 1.63 atmospheres. We know that the pressure was changed to 2.4 atmospheres, but we don't know the volume. Substitute all known values into the formula.

$4.5 \ L * 1.63 \ atm= 2.4 \ atm * V_2$

Since we are solving for the new volume (V₂), we need to isolate the variable. It is being multiplied by 2.4 atmospheres and the inverse of multiplication is division. Divide both sides by 2.4 atm.

$\frac {4.5 \ L * 1.63 \ atm}{2.4 \ atm}= \frac{2.4 \ atm * V_2}{2.4 \ atm}$

$\frac {4.5 \ L * 1.63 \ atm}{2.4 \ atm}= V_2$

The units of atmospheres (atm) cancel.

$\frac {4.5 \ L * 1.63 }{2.4 }=V_2$

$\frac {7.335 \ L}{2.4 }=V_2$

$3.05625 \ L= V_2$

The smallest number of significant figures in the original measurements is 2, so our answer must have the same. For the number we found, that is the tenths place.

The 5 in the hundredth place tells us to round the 0 up to a 1.

$3.1 \ L = V_2$

The volume of the neon gas when the pressure is changed to 2.4 atmospheres is <u>3.1 Liters.</u>

For the following reaction, 22.8 grams of diphosphorus pentoxide are allowed to react with 13.5 grams of water . diphosphorus pe

gavmur [86]

Answer:

$m_{H_3PO_4}=31.5gH_3PO_4$

Explanation:

Hello,

In this case, the undergoing chemical reaction is:

$P_2O_5(s)+3H_2O(l)\rightarrow 2H_3PO_4(aq)$

Thus, since the diphosphorus pentoxide to water molar ratio is 1:3 and we are given the mass of both of them, for the calculation of the maximum mass phosphoric acid that is yielded, one could first identify the limiting reactant, for which we compute the available moles of diphosphorus pentoxide (molar mass 142 g/mol):

$n_{P_2O_5}=22.8gP_2O_5*\frac{1molP_2O_5}{142gP_2O_5}=0.161molP_2O_5$

And the moles of diphosphorus pentoxide that are consumed by 13.5 g of water (molar mass 18 g/mol):

$n_{P_2O_5}^{consumed}=13.5gH_2O*\frac{1molH_2O}{18gH_2O}*\frac{1molP_2O_5}{3molH_2O} =0.25molP_2O_5$

Hence, since less moles of diphosphorus pentoxide are available, we sum up it is the limiting reactant, therefore, the maximum mass of phosphoric acid (molar mass 98 g/mol) is computed by considering the 1:2 molar ratio between them as follows:

$m_{H_3PO_4}=0.161molP_2O_5*\frac{2molH_3PO_4}{1molP_2O_5} *\frac{98gH_3PO_4}{1molH_3PO_4} \\\\m_{H_3PO_4}=31.5gH_3PO_4$

Regards.
