.774atm
First, look at what you have and look at the equations you can use to solve this problem. The best equation would be PV=nRT.
P being pressure, V being volume, n being moles, R being the gas constant, and T being temperature.
Before you start doing any of the math, make sure of two things. Since you're looking for pressure, you'll need a gas constant. When I did the problem, I used the gas constant of atm or atmospheres which is .0821.
Also! Remember to always convert celsius into kelvin, to do this, add 273 to the given celsius degree. After this is all set and done, your equation should look like this:
P = 
The reason that the equation is divided by the volume is due to the fact that you need to isolate the variable or pressure.
Multiply everything on the top and divide by the bottom and you should receive the final answer of .774atm.
Hope this helps!

Answer:
C.Melt both cubes and look for a broader range of melting temperatures. The one that melts over a broader range of temperatures is the amorphous solid.
Explanation:
Amorphous solids is one that do not have a fixed melting points but melt over a wide range of temperature due to the irregular shape hence its name. Contrariwise crystalline solids, have a fixed and sharp melting point.
This comes in handy to solve the riddle. We can characterise the pair with the melting point property.
Answer:
pH = - log [2.12 x 10^-3]
what is the log of 2.22 x 10^-3]
Take the opposite of that,
That is the pH, now, just make certain you use the correct significant figures.
Explanation:
Atmospheric pressure from barometer = (9810) × (13.6) × (0.720) = 96060 Pa = 96.06 kPa Absolute pressure in compartment A, 496.06 kPa P = P + P abs, A gauge, A atm = 400 + 96.06 = Absolute Pressure from barometer
