<span>The correct answer is KINETIC THEORY. Kinetic theory states that matters are made up of small particles which are constantly in motion. The kinetic theory helps to explain the behavior of the particles of solids, liquid and gases. For instance, the theory explain that the particle of gases are far apart because of the weak intermolecular forces among them and they are always in constant, random motion, colliding with one another and with the wall of the container.</span><span />

Make a decision about the molecule NaHCO3 classification organic or inorganic
motikmotik

<u>Answer:</u>

NaHCO_{3} is an inorganic compound.

<u>Solution:</u>

  1. Firstly, all the known definitions of organic compounds excludes Carbonic acid and it's salt from organic compounds except if 'C' is present in the cation.  
  2. Secondly, Sodium is a metal which organic compounds cannot posses as a compound.  
  3. Lastly, there is absence of C-H bond which is present in all the organic compounds.

Hence, we can conclude that NaHCO_{3}is an inorganic compound though there is presence of Carbon atom in it.

Na + Cl2 --&gt; NaCl if you were given 15 grams of sodium (with excess chlorine) and asked to determine the amount of NaCl that
Elena-2011 [213]

Answer:

The correct answer is - 38.15 gm of NaCl.

Explanation:

Write the balanced equation for this reaction of sodium (Na) and chlorine (Cl₂) to produce sodium chloride (NaCl):

2Na + Cl₂ —> 2NaCl

the mass of Na and the mass of NaCl :

Molar mass of Na = 23 g/mol

In the balanced equation = 2 × 23 = 46 g

Molar mass of NaCl = 23 + 35.5

= 58.5 g/mol

similarly in balanced equation = 2 × 58.5 = 117 g

From the balanced equation above,

46 g of Na reacted to produce 117 g of NaCl.

By converting it to 15 grams of Na.

Therefore,15 g of Na will react to produce = (15 × 117)/46 = 38.15 g of NaCl.

Thus, 38.15 g of Na
