1 answer:
dezoksy [38]3 years ago
3 0

Answer :

The substance is in the gas phase only in region  → 5

The substance is in both the liquid and the solid  phase in region  → 2

The substance is in only the liquid phase in region  → 3

The melting point is the temperature at region  → 2

The boiling point is the temperature at region → 4

Explanation :

Six phases of substance:

  • Melting or fusion : In this process the phase changes from solid state to liquid state at constant temperature.
  • Freezing : In this process the phase changes from liquid state to solid state at constant temperature.
  • Evaporation : In this process the phase changes from liquid state to gaseous state at constant temperature.
  • Condensation : In this process the phase changes from gaseous state to liquid state at constant temperature.
  • Sublimation : In this process the phase changes from solid state to gaseous state without passing through the liquid state at constant temperature.
  • Deposition : In this process the phase changes from gaseous state to solid state without passing through the liquid state at constant temperature.

Give the quantum number set for one electron in the 3p sub level of a sulfur (S)
vesna_86 [32]

Answer:- Atomic number for sulfur is 16 and it's electron configuration is 1s^2 2s^2 2p^6 3s^2 3p^4. Here, there are total for electrons in 3p and the set of quantum numbers for these 4 electrons would be as..

For the first electron of 3p-

n = 3, l = 1, ml = -1 and ms = +(1/2)

for the second electron of 3p-

n = 3, l = 1, ml = 0 and ms = +(1/2)

for the third electron of 3p-

n = 3, l = 1, ml = +1 and ms = +(1/2)

and for the fourth electron of 3p-

n = 3, l = 1, ml = -1 and ms = -(1/2)

How many moles of FeCl3 could be produced from 6.1 moles of Cly?<br> 2 Fe + 3Cl2 —&gt; 2 FeCl2
Black_prince [1.1K]

Answer:

4.1 moles of FeCl₃

Explanation:

The reaction expression is given as shown below:

         2Fe    +       3Cl₂   →    2FeCl₃

Number of moles of Cl₂  = 6.1moles

So;

  We know that from the balanced reaction expression:

                       3 moles of Cl₂ will produce 2 moles of FeCl₃

Therefore    6.1moles of Cl₂ will produce \frac{6.1 x 2}{3}   = 4.1 moles of FeCl₃

The number of moles is 4.1 moles of FeCl₃

You heat 51 grams of magnesium over a Bunsen burner for several minutes until it reacts with oxygen in the air. Then you weigh t
garik1379 [7]

Answer:

    The mass was there all along, it was just in the air. The weight of the oxygen from the air is not weighed in the beginning, only at the end as part of the product, making it seem like there is a total mass change.

How would you know if this combination is likely to be found in dirt? Please explain!
Elan Coil [88]
No it is not likely. That is a ratio of 10:4 N^14 and N^15 which doesn’t work. It needs a higher amount
