Is BH2F a gas or a liquid and what is the boiling point

Answers

Hey I tried but could not find your answer, but maybe you could try to calculate the average of bpts of the different elements in the compound to find the boiling point. And when you know the bpt, you can find out whether it is a liquid or gas. But after searching a lot, I found it was a solid. Good luck!

What is the word equation for molecules of magnesium reacting with molecules of oxygen to produce molecules of magnesium oxide?magnesium + magnesium oxide = oxygen
magnesium + oxygen =magnesium oxide
magnesium oxide = magnesium
magnesium + oxygen magnesium + oxygen

Answers

Answer:   magnesium + oxygen =magnesium oxide

Explanation:  When Magnesium reacts with the molecules of oxygen , Magnesium oxide is produced.

                        Mg (s) + O (g)   →   MgO (s)

In this equation, both magnesium and oxygen are present in its elemental state.

Magnesium is present in solid form and oxygen is present in gaseous form.

The Bonding between the Magnesium and the oxygen is purely IONIC bonding as Magnesium loses its 2 valence electrons to complete its octet and oxygen gains its electrons to make its electron count 8 in the valence shell.

Answer: (B) Magnesium + oxygen =magnesium oxide

Explanation:

Which of the following best describes solids?A. Solids are low in density and compressible.
B. Solids are high in density and compressible.
C. Solids are low in density and incompressible.
D. Solids are high in density and incompressible.

Answers

Answer: Option (D) is the correct answer.

Explanation:

Solids are the substances whose molecules are closely packed together due strong inter molecular forces between them. This causes the solid to have a fixed shape and volume.

Whereas density is mass divided by per unit volume.

Mathematically,         Density = (mass)/(volume)

Since, density is proportional to mass. So, more is the mass that is, more is the number of molecules held together by strong forces more will be its density.

Therefore, we can conclude that the statement solids are high in density and incompressible, best describes solids.
In my opinion I would pick D. 

Multiple answers could be chosen, just due to the fact that a solid is nothing more than just an object that cannot change it's physical shape into an object; just as water would. a solid can have a low density; such as paper, plastics, or even just a piece of wood. 

But think of a block of ice. You can break it, and crush it. It cannot be formed into any other shape. If you did break it, it only would make more ice fragments. And it's next phase is a liquid; if it were to be melted.

True or False, A Bronsted-Lowry acid is a proton acceptor, while a Bronsted-Lowry base is a proton donor.

Answers

This statement is false. A Bronsted-Lowry acid is a proton DONOR and the Bronsted-Lowry base is a proton ACCEPTOR, Based on the Bronsted-Lowry definition, acids and bases are being classified whether they can donate or accept and proton. Bronsted-Lowry acid is a PROTON DONOR because it donates a proton to H2O and for the Bronsted-Lowry base, it basically accepts a proton from acids such as HCl. 

Which refers to a mixture that contains more than one phase in which the characteristics of the particles vary throughout the mixture?

Answers

This type of mixture is a heterogeneous mixture. It is any mixture that is not uniform. Heterogeneous mixtures always have more than one phase.It is made up of substances which stays physically separate with each other. Best example is a mixture of sand and sugar. If you get two samples from different points of the mixture and analyze it, you will see that the concentrations of the components are different and that the two solid phases never combine with each other.

Answer:

C. Heterogeneous

Explanation:

Answers

If the probability of rain is 85%, then the probability of no rain would be 100% - 85% = 15%. Therefore, the correct answer is 15%.
