State briefly the similarities and differences between the theories of Arrhenius and Bronsted-Lowry
ludmilkaskok [199]
My answer to the question above is not the best example but I hope it will help you. <span>The Arrhenius model says that acids always contain H+ and that bases always contain OH-. </span>
<span>The Bronsted-Lowry model thinks of acids as being proton donors and proton acceptors, so bases no longer need to contain OH-, and acids donate a proton to water forming H3O+. </span>
<span>Lewis acids are electron pair acceptors, and Lewis bases are electron pair donors. For instance, H+ + OH- => H20. H+ has no electrons, so when it bonds to the Oxygen, it gains an electron pair. OH- "loses" an electron pair.</span>

A 7.0 L sample of gas begins at 2.5 atm and 320. K. What is the new pressure if the temperature is changed to 273 K and the volu
enyata [817]

Answer:

2.1 atm

Explanation:

We are given the following variables to work with:

Initial pressure (P1): 2.5 atm

Initial temperature (T1): 320 K

Final temperature (T2): 273 K

Constant volume: 7.0 L

We are asked to find the final pressure (P2). Since volume is constant, we want to choose a gas law equation that relates initial pressure and temperature to final pressure and temperature. Gay-Lussac's law does this:

\frac{P_{1}}{T_1} =\frac{P_{2}}{T_2} \\

We can rearrange the law algebraically to solve for P_{2}.

{P_{2}} =\frac{(T_2)(P_{1} )}{T_1} \\

Substitute your known variables and solve:

P_2 = \frac{273K(2.5atm)}{320K}  = 2.1 atm

Which are forms of frozen water? Check all that apply. dew frost hail rain sleet
MariettaO [177]

When moist air cools below its dew point on a cold surface it forms dew. It is in the liquid state.

Rain is again a form of precipitation in which water is in the liquid state.

When air temperature is below freezing, the precipitation that results is referred to as frost. Hail is a form of precipitation in the ice balls whereas as sleet is a mixture of rain and snow.

Ans: Forms of frozen water- frost, hail and sleet
