Which electron configuration represents the element carbon (atomic number 6)?

The hydrogen gas formed in a chemical reaction is collected over water at 30.0 ∘c at a total pressure of 734 mmhg . part a what

In-s [12.5K]

At a temperature of 30 deg C, the vapour pressure of water H2O is about 32 mm Hg. Therefore at a total pressure f 734 mm Hg, the partial pressure of the Hydrogen gas collected is:

<span>P Hydrogen = 734 mm Hg – 32 mm Hg = 702 mm Hg</span>

You take a bottle of soft drink out of your refrigerator. The contents are liquid and stay liquid, even when you shake them. Pre

inna [77]

Answer:

The correct answer is due to the difference in pressure inside and outside the bottle.

Explanation:

Liquids have melting and boiling points that depend on pressure and temperature. The pressure inside the bottle is higher than the pressure outside. This causes the melting point to drop, making the liquid freeze at a lower temperature than if it were at atmospheric pressure, and therefore has a lower temperature than it would freeze at atmospheric pressure. When the bottle is uncovered, the liquid becomes an atmospheric pressure, and due to the temperature acquired when the bottle was closed the liquid freezes.

Have a nice day!
