The element iodine would be expected to form covalent bond(s) in order to obey the octet rule. Use the octet rule to predict the

zhannawk [14.2K]

Answer:

HI (hydrogen iodide).

Explanation:

Hello,

In this case, since iodine is in group VIIA, it has seven valence electrons at its outer shell, which means that it only needs one bond to attain the octet. Moreover, since hydrogen has just one electron at its outer shell, one hydrogen turns out enough to obey the octet when hydrogen and iodine bond as shown below:

$H-I$

Therefore, the required formula is:

$HI$

Which is hydrogen iodide.

Best regards.

True or false: (a) For molecules with similar molecular weights, the dispersion forces become stronger as the molecules become m

g100num [7]

Answer:

A ,B- false

C,D- true

Explanation:

Dipole forces always lead to stronger attraction and boiling points than dispersion forces. When linear molecules are involved, they often posses greater dipole forces and higher boiling points. Linear alkanes posses higher boiling points than branched alkanes.

Predict which of the following changes will cause the volume of the balloon to increase or decrease assuming that the temperatur

IrinaVladis [17]

Answer:

1. a

2. a

3. b

4. c

Explanation:

The STP is the Standard conditions of Temperature and Pressure, in these conditions, T = 0°C and P = 1 atm. By the ideal gas law,

PV = nRT

Where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.

We can observe that pressure and volume are indirect proportional, so when one increase, the other decrease. so:

1. The pressure decreases from 1.15 atm to STP, 1 atm, thus the volume increases.

2. The pressure decreases from STP, 1 atm, to 0.5 atm, thus the volume increases.

3. The pressure increases from STP, 1 atm, to 1.25 atm, thus the volume decreases.

4. The pressure remains constant at 1 atm, thus the volume is unchanged.
