I don’t really know but Yk how they are categorized by color try checking the atomic levels or some around that hope I was some type of help
Mass of water is 11.52 grams.
Overall chemical equation for reaction of combustion a compound containing only carbon and hydrogen:
CxHy + O₂ → xCO₂ + y/2H₂O
m(CxHy) = 7.02 g; mass of the compound
m(O₂) = 25.5 g; mass of oxygen
m(CO₂) = 21.0 g; mass of carbon dioxide
m(H₂O) = ?; mass of water
Conservation of matter states that the mass of the reactants have to be equal to the mass of the products.
m(CxHy) + m(O₂) = m(CO₂) + m(H₂O)
7.02 g + 25.5 g = 21.0 g + m(H₂O)
m(H₂O) = 32.52 g - 21.0 g
m(H₂O) = 11.52 g; mass of water

Answer:
1. Mass of New atom = 208
2. Atomic number of the new atom is 82
3. Symbol of the new atom is Pb
Explanation:
²¹²₈₄Po —> ⁴₂He + ᴬZX
1. Determination of the mass A of the new atom.
212 = 4 + A
Collect like terms
212 – 4 = A
208 = A
A = 208
Therefore, the mass of the new atom is 208
2. Determination of the atomic number of the new atom.
84 = 2 + Z
Collect like terms
84 – 2 = Z
82 = Z
Z = 82
Therefore, the atomic number of the new atom is 82
3. Determination of symbol of the new atom
The atomic number of the new atom is 82. Comparing the atomic number of the new atom (i.e 82) with those in the periodic table, the new atom is Lead.
Lead has a symbol of Pb
Thus,
Mass of new atom (A) = 208
Atomic number of new atom (Z) = 82
Symbol of new atom (X) = Pb
Therefore,
ᴬZX = ²⁰⁸₈₂Pb
Answer:
Which models of the atom from task 1 are not supported by Rutherford’s experimental evidence? For each of these models, explain the experimental results that the model would predict.
where is the model
You will need the Gas Law:
pV = nRT
Since T and p are constant, R is constant too, then moles increases->volume will increase with the same ratio too!
