How does the sharing of bonding electrons in a molecule of Cl2 compare to that in a molecule of HCI?

Ronch [10]

The chlorine atom bonds through covalent bond to obtain an octet structure so two atoms of 2,8,7 come together and HCl consists of both metal and nonmetal which is the the covalent bonding principle so H and Cl share the 8 valence electrons to obtain an octet structure.

Consider solutions A and B

lisabon 2012 [21]

Answer: Option c. Solution A has a lower boiling point than solution B

Explanation:

For solution A, i = 1 means the solution is a non-electrolyte. This clearly indicates that solution A contains covalently bonded compound. Covalently bonded compounds have lower boiling when compared to those of the ionic.

For solution B, i = 2 means the compound is an electrolyte and it forms two ions. From this result, it is very clear that the compound in solution A is an ionic compound. Ionic compounds have higher boiling points than covalent compounds

Therefore, solution A will have a lower boiling point than solution B

Recall that your hypothesis is that these values are the fraction of atoms that are still radioactive after n half-life cycles.

jolli1 [7]

Answer : A= 0.5, B = 0.25 , C = 0.125, D = 0.015625 and E = 0.00390625

Explanation :

Half life of a substance is defined as the amount of time taken by the substance to reduce to half of its original amount.

Here n represents the number of half lives.

The amount of substance that remains after n half lives can be calculated using the given formula, $0.5^{n}$

So when we have n =1,

Fraction of substance that remains = 0.5¹ = 0.5.

That means after first half life over, the amount of substance that remains is 0.5 times that of original.

Therefore we have A = 0.5

When n = 2, we have 0.5² = 0.25

So when 2 half lives are over, the amount of substance that remains is 0.25 times that of original

Therefore B = 0.25

When n = 3, we have 0.5³ = 0.125

So when 3 half lives are over, the amount of substance that remains is 0.125 times that of original.

Therefore we have C = 0.125

When n = 6 , we have 0.5⁶ = 0.015625

So D = 0.015625

When n = 8, we have 0.5⁸ = 0.00390625

Therefore E = 0.00390625

The values for A, B, C, D and E are 0.5, 0.25, 0.125, 0.015625 and 0.00390625 respectively.

A 600.0 mL sample of krypton is held at standard conditions. What volume does the gas occupy when the pressure is tripled and th

solong [7]

<u>Answer:</u> The volume when the pressure and temperature has changed is 400 mL

<u>Explanation:</u>

To calculate the volume when temperature and pressure has changed, we use the equation given by combined gas law.

The equation follows:

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

where,

$P_1,V_1\text{ and }T_1$ are the initial pressure, volume and temperature of the gas

$P_2,V_2\text{ and }T_2$ are the final pressure, volume and temperature of the gas

We are given:

$P_1=P_1\\V_1=600.00mL\\T_1=T_1\\P_2=3P_1\\V_2=?\\T_2=2T_1$

Putting values in above equation, we get:

$\frac{P_1\times 600mL}{T_1}=\frac{3P_1\times V_2}{2T_1}\\\\V_2=\frac{600\times P_1\times 2T_1}{T_1\times 3P_1}=400mL$

Hence, the volume when the pressure and temperature has changed is 400 mL
