Answer: The correct answer is Option 3.

Explanation:

Hydrocarbon is defined as the species in which a covalent bond is present between only hydrogen and carbon atoms. Presence of only hydrogen and carbon atoms is considered as a hydrocarbon.

From the given options:

Option 1: $CH_3I$

Here, a bond is present between carbon and iodine. Thus, it is not considered as a hydrocarbon.

Option 2: $CH_3NH_2$

Here, a bond is present between carbon and nitrogen. Thus, it is not considered as a hydrocarbon.

Option 3: $CH_3CH_3$

Here, a bond is present between carbon and hydrogen. Thus, it is considered as a hydrocarbon.

Option 4: $CH_3OH$

Here, a bond is present between carbon and oxygen. Thus, it is not considered as a hydrocarbon.

Hence, the correct answer is Option 3.

What is the difference between the 3p sublevel and the 4p sublevel? On the periodic table

statuscvo [17]

The p sublevels are named 2p, 3p, and 4p since the p sublevel appears only starting the 2nd level. By the Aufbau principle, 3p will be filled first before 4p. This is because of the energy present on the level.

Each of the p sublevel has 3 orbitals, allowing them to contain 6 electrons as each orbital may hold two.

Perform unit conversions and determine Re for the case when a fluid with density of 92.8 lbm/ft3 and viscosity of 4.1 cP (centip

erastovalidia [21]

Answer:

Re=309926.13

Explanation:

density=92.8lbm/ft3*(0.45kg/1lbm)*(1ft3/0.028m3)=1491.43kg/m3

viscosity=4.1cP*((1*10-3kg/m*s)/1cP)=0.0041kg/m*s

velocity=237ft/min*(1min/60s)*(0.3048m/1ft)=1.2m/s

diameter=28inch*(0.0254m/1inch)=0.71m

Re=(density*velocity*diameter)/viscosity=(1491.43kg/m3*1.2m/s*0.71m)/0.0041kg/m*s

Re=309926.13

When nonpolar solutes are placed in water, the hydrogen bonding network of water is disrupted, and there are fewer ways for wate

satela [25.4K]

Answer: increase in entropy

Explanation:

Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.

$\Delta S$ is positive when randomness increases and $\Delta S$ is negative when randomness decreases.

When the non polar solutes are placed in water, the hydrogen bonding network of water is disrupted, and there are fewer ways for water to hydrogen-bond with itself. That means the water molecules are more randomly arranged and thus have more entropy and thus $\Delta S$ is positive.
