Yes you are right .. X is undergoing a change from solid to gas at point E
Olin [163]3 years ago
5 0

Yes you are right as from the phase diagram it can be seen :

A. Substance X is in the solid phase in the area shown by “1”.


B. Substance X exists as a solid, a liquid and a gas at point D.

D. Substance X is a liquid in the area shown by "2"

But the point C is not correct as Substance X is not undergoing a change from a liquid to a gas at the line shown by E while it undergoes a phase change from solid to gas.

The three beakers shown below contain solutions of [cof6]3–, [co(nh3)6]3+, and [co(cn)6]3–. based on the colors of the three sol
vitfil [10]
[Co(CN)₆]³⁻ → Yellow
[Co(NH₃)₆]³⁺ → Orange
[CoF₆]³⁻ → Blue
Explanation:
- All the given compounds have octahedral geometry but the ligand in each are different with the same metal ion.

- Ligands strength order:     CN⁻ > NH₃ > F⁻ 

- The ligand CN will act as a strong field ligand so that the splitting is maximum when compared to NH₃ and F⁻

- If the splitting is more, the energy required for transition is more, and the wavelength is inversely proportional to energy.

- So CN complex will absorb at lower wavelength (yellow color)

If an isotope of oxygen has 8 protons, 10 neutrons, and 8 electrons, its mass number is_______.
melamori03 [73]

Answer:

mass number = 18

Explanation:

The mass number is the total amount of protons and neutrons in an atom. Therefore, if there are 8 protons and 10 neutrons, the mass number is 18 (8 + 10 = 18).

What is the molarity of a solution in which 25g NaCl in a 2.00 L solution?
Paladinen [302]

Mass of sodium :- 23 grams

Mass of Chlorine :- 35.5 grams

Mass of NaCl :- 58.5 grams

mass given :- 25 grams

moles :- 0.432 ( given mass/ ionic mass)

molarity =   \frac{moles}{vol}  \\ molarity =  \frac{0.432}{2}  \\ molarity = 0.216 \: mole{l}^{ - 1} or \: molar

You add 100.0 g of water at 52.0 °C to 100.0 g of ice at 0.00 °C. Some of the ice melts and cools the water to 0.00 °C. When the
lara31 [8.8K]

Answer:

m_{ice} = 65.336\,g

Explanation:

Accoding to the First Law of Thermodynamics, the heat released by the water melts a portion of ice. That is to say:

Q_{water} = Q_{ice}

(100\,g)\cdot \left(4.184\,\frac{J}{kg\cdot ^{\textdegree}C}\right)\cdot (52\,^{\textdegree}C - 0\,^{\textdegree}C) = m_{ice}\cdot \left(333\,\frac{J}{g} \right)

The amount of ice that is melt is:

m_{ice} = 65.336\,g
