Are electrons protons and neutrons the smallest particles?.
Norma-Jean [14]
<h2><u>Answer</u> : No</h2>

<h3><u>Brief explanation</u>:</h3>

<em>John Dalton considered atom as the smallest particle but later on this theory failed due to discovery of electron,proton and neutron. This three are the subatomic atomic particle. Later on Murray Gell-Mann discovered the quarks which forms the neutrons and protons and determine overall charge on them. </em>

<u>Conclusion</u> - Electron, proton and neutron are subatomic particles not smallest particles.

Solid calcium chlorate decomposes to form solid calcium chloride and oxygen gas.
3241004551 [841]

Answer:

Ca(ClO₃)₂(s)      →      CaCl₂(s) + 3O₂(g)

Explanation:

Chemical equation:

Ca(ClO₃)₂(s)      →      CaCl₂(s) + O₂(g)

Balance chemical equation:

Ca(ClO₃)₂(s)      →      CaCl₂(s) + 3O₂(g)

Step 1:

Ca(ClO₃)₂(s)      →      CaCl₂(s) + O₂(g)

Left hand side                     Right hand side

Ca = 1                                     Ca = 1

Cl = 2                                     Cl = 2

O =  6                                     O = 2

Step 2:

 Ca(ClO₃)₂(s)      →      CaCl₂(s) + 3O₂(g)

Left hand side                     Right hand side

Ca = 1                                     Ca = 1

Cl = 2                                     Cl = 2

O =  6                                     O = 6

How many molecules of CO2 are equivalent to 112g CO2 scientific figures
Troyanec [42]

Answer:

N(CO2) = n(CO2) x Avogadros constant

n(CO2) = mass(CO2)/Molar mass(CO2) = 112/44 = 2.5454….

N(CO2) = 2.545454… x (6.02 x 10^23) = 1.5323636 x 10^24

Therefore, the number of CO2 molecules in 112 g of CO2 = 1.53 x 10^24 molecules
