Answer: Solids

Explanation:

In the solid state, the individual particles of a substance are in fixed positions with respect to each other because there is not enough thermal energy to overcome the intermolecular interactions between the particles. As a result, solids have a definite shape and volume.

How does a lithium cation compare to a lithium atom?
kirill [66]

Lithium cation and Lithium atom can be compared as follow;

<h3>1) Charge:</h3>

              The charge on Lithium atom is zero means, it has same number of protons and electrons. Hence, the nert effect is cancelled out and the atom gets zero charge.

               On the other hand, Lithium cation is formed when it looses one electron. Therefore, the number of protons are greater by one number as compared to number of electrons resulting in the formation of +1 charge as shown below,

                                                Li    →    Li⁺¹  +  e⁻

<h3>2) Size:</h3>

           Secondly, Lithium atom has greater size as compared to Lithium cation because due to presence of greater number of protons compared to electrons in Lithium cation the nuclear charge appears to be greater as compared to neutral atom hence, pulling the valence electrons more effectively making the lithium cation smaller in size as compared to neutral atom.

<h3>3) Reactivity:</h3>

                     We can also compare the reactivity of both species. The neutral will be more reactive than the charged atom because it is containing one valence electron and can donate it when ever it comes in contact with non-metals.

which of the following measurements represents the most matter? 3.5 kg 350 g 3.5 x 103 hg 3.5 x 104 cg
LiRa [457]
The measurement with the highest weight has more matter.  
We shall convert all expression to kg.  
350g to kg = 0.350 kg 
1 kg is equals 100000 cg 
Then x kg is equals 3.5 * 104 cg. 
Hence 3.5 * 10^4 cg = 0.35kg 
Also 1 kg equals 10 hg 
Then x kg equals 3.5 * 103 
So x = 350 kg. Hence 3.5 * 103 hg is the answer

If you get some of the right sort of organic material, and heat it in the right sort of way, perhaps with a little squeezing, yo
AnnZ [28]

Question Options:

A) Bituminous, peat, lignite, anthracite.

B) Anthracite, bituminous, lignite, peat.

C) Peat, anthracite, lignite, bituminous.

D) Peat, lignite, bituminous, anthracite.

E) Bituminous, peat, anthracite, lignite.

Answer: Anthracite, bituminous, lignite, peat.

Explanation:

Anthracite is a form of carbonized ancient plants; the hardest and cleanest-burning of all the coals.

Bituminous is a form of coal that is characterized by mineral pitch; a black, tarry substance, burning with a bright flame.

Lignite is a low grade brownish coal.

Peat is a form of coal formed of dead but not fully decayed plants found in bog areas, often burned as fuel.

From the definitions given above, one can categorically say the most heated is in a descending order. And According to the Question, most heated is most valuable.
