Answer:

At one atmosphere and twenty-five degrees Celsius, could you turn it into a liquid by cooling it down? Um, and the key here is that the triple point eyes that minus fifty six point six degrees Celsius and it's at five point eleven ATMs. So at one atmospheric pressure, there's no way that you're ever going to reach the liquid days. So the first part of this question is the answer The answer to the first part of a question is no. How could you instead make the liquid at twenty-five degrees Celsius? Well, the critical point is at thirty-one point one degrees Celsius. So you know, if you're twenty-five, if you increase the pressure instead, you will briefly by it, be able to form a liquid. And if you continue Teo, you know, increase the pressure eventually form a salad, so increasing the pressure is the second part. If you increase the pressure of co two thirty-seven degrees Celsius, will you ever liquefy? No. Because then, if you're above thirty-one point one degrees Celsius in temperature. You'LL never be able to actually form the liquid. Instead, you'LL only is able Teo obtain supercritical co too, which is really cool thing. You know, they used supercritical sio tu tio decaffeinated coffee without, you know, adding a solvent that you'LL be able to taste, which is really cool. But no, you can't liquefy so two above thirty-one degrees Celsius or below five-point eleven atmospheric pressures anyway, that's how I answer this question. Hope this helped :)

If the temperature of the earth's layers increases by about 90 degrees fahrenheit for every 1 mile from the surface and you are
bogdanovich [222]
The rate of change of the temperature of the Earth's surface is given to,
                                       90°F/mile
To determine the temperature x miles away from the surface, we multiply the depth by the given rate. This will give us the answer of,
                                  T = (90°F/mile)(90 mile)
                                      = 8100°F
Thus, the temperature 90 miles deep in the Earth's surface is equal to 8100°F.

If you evaporated 125 mL of a 3.5 M solution of iron(II) nitrite, how many moles of iron(II) nitrite would you recover?
Serhud [2]

If 125 mL of a 3.5 M solution were evaporated, 0.438 moles of iron (II) nitrite would be recovered.

<h3>What is molarity?</h3>

Molarity is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of moles of solute per liter of solution.

We want to find the moles of iron (II) nitrite (solute) in 125 mL of a 3.5 M solution. We will use the definition of molarity.

M = n / V(L)

n = M × V(L) = 3.5 mol/L × 0.125 L = 0.438 mol

where,

  • M is the molarity.
  • n is the number of moles.
  • V(L) is the volume of the solution in liters.

If 125 mL of a 3.5 M solution were evaporated, 0.438 moles of iron (II) nitrite would be recovered.

Answer:

-273 C

Explanation:

k= c + 273

0 = c +273

273 goes negative and
