To express the given concentration of the solution to the same unit as the solubility of the salt, use dimensional analysis.
(360 g/ 1 L ) x (1 L / 10 (100 mL)) = 36 g / 100 mL
This value is equal to the value of the solubility of the salt which means that the solution is SATURATED.
Answer:
CuO + H2SO4 = CuSO4 + H2O
Reaction type: double replacement
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
