The question is asking to states the term that states an explosion that destroys the outer portion of a star, and base on my research, I would say that it is a Supernova, which is due to the death of a star. I hope you are satisfied with my answer and feel free to ask for more if you have question and further clarification

A supernova. This happens towards the end of the lifetime of a star. It is a massive explosion that eventually causes the collapse of a star which eventually will turn into a black hole. Sometimes when a start explodes it will shine brightly for weeks or months before eventually fading into black.

T/F___ At the eutectic composition, an alloy can solidify at a constant temperature.___ For effective dispersion strengthening,

azamat

Answer:

TRUE
FALSE
TRUE
FALSE
FALSE
TRUE

Explanation:

At the eutectic composition, an alloy can solidify at a constant temperature : TRUE . this is because at eutectic composition the type of reaction that takes place there is invariant reaction in its thermal equilibrium
For effective dispersion strengthening, the dispersed phase should be needle-like, as opposed to round : FALSE. because the rounded shape will not cause a crack.
Intermetallic compounds are usually hard and brittle : TRUE. because Intermetallic compounds prevents dislocation movements and this makes them brittle and hard
For the effective dispersion and strengthening, the dispersed phase should be continuous : FALSE. this is because the dispersed precipitate must be small and not continuous
Stoichiometric intermetallic compounds exist over a range of compositions : FALSE
Faster solidification results in smaller interlamellar spacing : TRUE

Please help me with this question

vampirchik [111]

Remember that

For being a bond covalent ∆E<1.8
For being a bond ionic ∆E>1.8

∆EN=0.5

Carbon is present so it's covalent

OH bond is also covalent

P-H will hardly form a bond

Ionic bond

Ionic bond

Rank the following compounds in order of decreasing boiling point: potassium fluoride (KF), acetylene (C2H2), and formaldehyde (

otez555 [7]

Answer: $KF$ > $CH_2O$ > $C_2H_2$

Explanation:

The order of boiling point depends upon the type of interactions present between the molecules.

Potassium fluoride (KF) is an ionic compound and the opposite ions are held together by strong electrostatic forces.

$C_2H_2$ is a covalent compound and the molecules are held together by weak van der Waals' forces.

Formaldehyde is a polar compound due to presence of polar carbonyl group. Hence dipole-dipole force is present between formaldehyde molecules.

Thus the decreasing order of boiling point is:

$KF$ > $CH_2O$ > $C_2H_2$
