The pressure of the gas would increase.

When gas is transported from a larger area to a smaller area it begins to increase in pressure.

A ruptured tank in Anywhere, USA, spilled hydrochloric acid. Officials were reported to be concerned that the acid might mix wit
lawyer [7]

Answer:

Option C; NONE.

Explanation:

A chemical reaction forms new chemicals called the products from the initial chemicals called the reactants. The reaction between an acid and a base is called neutralization, and the products formed are water and a salt.

When hy­drochlo­ric acid and sodi­um hy­drox­ide is mixed together, they in­ter­act, and re­sult­ in salt and a release of heat.

The re­sult of the in­ter­ac­tion of these two high­ly ag­gres­sive com­pounds is ta­ble salt and wa­ter, these resulting com­pounds are ul­ti­mate­ly harm­less, and even ben­e­fi­cial, to hu­man be­ings.

Therefore, NO TOXIC GAS WOULD BE FORMED BY MIXING HYDROCHLORIC ACID WITH SODIUM HYDROXIDE.

Draw the Lewis structure for methane (CH4) and ethane (C2H6) in the box below. Then predict which would have the higher boiling
Alinara [238K]

Answer:

Ethane would have a higher boiling point.

Explanation:

In this case, for the lewis structures, we have to keep in mind that all atoms must have <u>8 electrons</u> (except hydrogen). Additionally, each carbon would have <u>4 valence electrons</u>, with this in mind, for methane we have to put the hydrogens around the carbon, and with this structure, we will have 8 electrons for the carbon. In ethane, we will have a bond between the carbons, therefore we have to put three hydrogens around each carbon to obtain 8 electrons for each carbon.

Now, the main difference between methane and ethane is an <u>additional carbon</u>. In ethane, we have an additional carbon, therefore due to this additional carbon, we will have <u>more area of interaction</u> for ethane. If we have more area of interaction we have to give <u>more energy</u> to the molecule to convert from liquid to gas, so, the ethane will have a higher boiling point.

I hope it helps!
