In the first propagation step of the bromination of 2,3-dimethylbutane, the newly formed Br radicals react with the molecules of 2,3-dimethylbutane. Give the major products formed by the first propagation step including both organic and inorganic products. Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. Include all free radicals by right-clicking on an atom on the canvas and then using the Atom properties to select the monovalent radical.

Answer:

B) Ca(H2PO4)2

Explanation:

To solve this we must be knowing each and every concept related to chemical formula.  Therefore, the correct option is option B among all the given options.

The chemical formula is indeed a means of expressing information about just the chemical proportion of atoms that comprise a certain chemical compound as well as molecule through the use of chemical element numbers and symbols.

Furthermore, the molecular formula does not contain any words and does not serve as a chemical name. However, it just indicates basic chemical structures and is not the same as the entire chemical structural formula.  The correct formula for calcium dihydrogen phosphate is Ca(H[tex]_2[/tex]PO[tex]_4[/tex])[tex]_2[/tex].

Therefore, the correct option is option B among all the given options.

Not sure what you exactly mean, but I think what you are talking about are the spheres of earth (Lithosphere, Hydrosphere, Atmosphere, and Biosphere.)

Lithosphere (Terrestrial) is the land on earth. Hydrosphere (Hydrologic) is the water on earth.

I'm not sure if this is 100% correct but I'm guessing this is what you are referring to. It could be different across different science classes.

Answer:

Explanation:

It describes how much heat must be added to a unit of mass of a given substance to raise its temperature by one degree Celsius. ... The mass m, specific heat c, change in temperature ΔT, and heat added (or subtracted) Q are related by the equation: Q=mcΔT.

Answer:

The formula q=mcΔt explained below

Explanation:

so q represents the amount of heat energy. M is the mass of the object and c is the temperature of the object. Δt also known as delta is the change in temperature. It would be the final temperature minus the original temperature.

Answer:

No longer emitting heat or light, the white dwarf will become a black dwarf. Because it emits no radiation, it is nearly impossible to see. However, the black dwarf would still retain its mass, allowing scientists to detect the effects produced by its gravitational field.

Explanation:

Answer:

white dwarfs are hot, black dwarfs are cold

Explanation:

a white dwarf is a slowly burning and aging corpse of a main sequence star such as our sun. they are up to 40 times hotter then the sun, ranking among one of the hottest objects in the universe, except their luminosity is so low that all their heat stays in them basically forever.

On the other hand, a black dwarf is a theoretical ending to a white dwarf, over the course of trillions of years, white dwarfs cool down into black dwarfs. black dwarfs rank among the coldest possible temperature. We aren't sure if these are really a thing, because we still haven't given white dwarfs enough time to cool down.

Answer:

Detail is given below.

Explanation:

Atomic radius  trend along period:

As we move from left to right across the periodic table the number of valance electrons increases. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required.

we can see in picture A there is one positive charge and force of attraction is 2.30×10⁻⁸ N

In picture D there are 2 positive charge and force of attraction is 4.60×10⁻⁸ N

So by increasing the positive charge force of attraction also increases.

In F we can see there is more positive charge thus force of attraction is also greater.
