Answer:
Compound 1- ionic solid
Compound 2- can't really decide
Compound 3- molecular solid
Explanation:
An ionic solid has a very high melting point. It is hard but not brittle. It's solution or melt but not it's solid conducts electricity. Compound 1 is an ionic solid.
We can't really decide on compound 2 since it is brittle yet it's solution conducts electricity.
Lastly, compound 3 is a molecular solid since it has a low melting point.
Answer:
Homogeneous and heterogeneous
Explanation:
690 Kelvin is the boiling point of this compound.
Explanation:
Enthalpy is the sum of internal energy and the product of pressure and volume that is how much energy is in the substance.
Entropy is the measurement of randomness and measure of thermal energy per unit of temperature.
ΔH vap of compound is 46.55 kJ⋅ mol− or J.MOL-1
ΔS vap is 67.37 J⋅mol−1⋅K−1.
The boiling point or temperature can be calculated by the formula:
T=
T =
= 690 Kelvin
The boiling point is the temperature when atmospheric temperature gets equal to
Answer:
In aqueous solution, HF is an acid, exist as a mixture of molecules and ions
CH3CN is none of the above, entirely in molecular form
NaCIO4 is a salt, entirely as ions
Ba(OH)2 is a base, entirely as ions
Answer:
The answer is "Orion technology"
Explanation:
NASA tested that perhaps the abort system on the Biomechanical properties fires faster than that of the rocket, possibly costing colonists during launch or a crisis. It test is a significant step forward in Agency's plans again for the Artemis space mission, which will pave the way for human missions to The moon. NASA is building a humanoid spacecraft for long-range space missions for the first time in generations. As just a result, they are beginning a new age of space travel. Orion would be used to transport the crew into space as a surveillance vehicle. Also, it helps astronauts to flights and ensures a safe return to orbit in the case of an emergency release.
