Yes because the deeper the water is the more it has to freeze so if it is thin then it will take less time to freeze <span />

The more surface area exposed, the faster it freezes. The less surface area exposed, the slower it freezes.

Ugo [173]

The reaction $Na_{3} PO_{4} ( aq) +3AgNO_{3} (aq)$ → $Ag_{3} PO_{4} ( aq) +3NaNO_{3} (aq)$ is best classified as double displacement reaction.

Those reaction in which two compounds react by exchanges of ions to form two new compounds is called double displacement reaction. The easiest way to identify double displacement reactions is to check to see whether the cations exchanged anions with each other or not . Always balanced chemical equation is used to determine.

There are three types of double displacement reaction which is given as,

Precipitation
Neutralization
Gas formation

The real world example of double displacement reaction is combining vinegar and baking soda to create homemade volcano.

A gas tank holds 20000 liters at 850 torr. If the temperature remains constant, what will the volume, in L, of the gas be at sta

nekit [7.7K]

Answer: 22368.4 Liters

Explanation:

Initial Volume of gas V1 = 20000 liters

Initial pressure of gas P1 = 850 torr

Final volume V2 = ?

Final (standard) pressure P2 = 760 torr

Apply the formula for Boyle's law:

P1V1 = P2V2

850torr x 20000L = 760torr x V2

V2 = (850torr x 20000L)/ 760torr

V2 = (17000000)/760torr

V2 = 22368.4L

Thus, the volume of the gas at standard pressure is 22368.4 Liters
