Question 5 of 10
djyliett [7]

A. A diagram showing the effects of temperature and pressure on  phase

Explanation:

A phase diagram is a diagram that shows the effects of temperature and pressure on phase.

  • A phase diagram shows how different substances are transformed from one form to another.
  • The transformation is an interplay between pressure and temperature.
  • The phase graph represents physical state changes.
  • A phase change is made up of pressure on the y-axis and temperature on the x - axis.

A person accidentally swallows three drops of liquid oxygen, , which has a density of 1.149 g/ml. assuming the drop has a volume
DerKrebs [107]
<span>134 ml First, let's determine how many moles of oxygen we have. Atomic weight oxygen = 15.999 Molar mass O2 = 2*15.999 = 31.998 g/mol We have 3 drops at 0.050 ml each for a total volume of 3*0.050ml = 0.150 ml Since the density is 1.149 g/mol, we have 1.149 g/ml * 0.150 ml = 0.17235 g of O2 Divide the number of grams by the molar mass to get the number of moles 0.17235 g / 31.998 g/mol = 0.005386274 mol Now we can use the ideal gas law. The equation PV = nRT where P = pressure (1.0 atm) V = volume n = number of moles (0.005386274 mol) R = ideal gas constant (0.082057338 L*atm/(K*mol) ) T = Absolute temperature ( 30 + 273.15 = 303.15 K) Now take the formula and solve for V, then substitute the known values and solve. PV = nRT V = nRT/P V = 0.005386274 mol * 0.082057338 L*atm/(K*mol) * 303.15 K / 1.0 atm V = 0.000441983 L*atm/(K*) * 303.15 K / 1.0 atm V = 0.133987239 L*atm / 1.0 atm V = 0.133987239 L So the volume (rounded to 3 significant figures) will be 134 ml.</span>

irina [24]

Answer: It gets wasted in various forms.

Explanation: The most common way of this energy being wasted is called "waste heat".

Waste heat is the unused heat given to the surrounding environment (in the form of thermal energy) by a heat engine in a thermodynamic process (like a chemical reaction as you said) in which it converts heat to useful work.

3) What is the mass of a sample consisting of 1.00 X 1022 formula units of MgSO.?(​
Montano1993 [528]

number of moles = 1.00 X 10^22 ÷ 6.022 × 10^23

= 0.0166 moles

mass = number of moles × molar mass

= 0.0166 × 120.37 = 2.00 g
