the answer is body fossils which is B) body
Physical only because if i were to cut paper, it is still paper
<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.

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
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
