<u>Answer: </u>The chemical formula for Palladium(IV) sulfate is
<u>Explanation:</u>
Palladium is the 46th element of the periodic table which has an oxidation state of +4 (because it is a metal and will form positive ion) and sulfate is the polyatomic ion having a charge of -2 with formula
So, to write the formula of the compound, we do criss cross method in which oxidation state of each element or ion is given to the other combining atom which results into the formation of a neutral compound.
The chemical formula of the compound is
The image is given below.
Answer:
Matthias Jacob Schleiden was a German botanist who, with Theodor Schwann, cofounded the cell theory. In 1838 Schleiden defined the cell as the basic unit of plant structure, and a year later Schwann defined the cell as the basic unit of animal structure.
Explanation:
Answers:
1.
The mole ratio of AlCl₃ to Cl₂ is 2 : 3. This means for production of every 2 moles of AlCl₃ 3 moles of Cl₂ is consumed. Hence, if 3 moles of AlCl₃ is produced then Cl₂ consumed is,
= 3 × 3 / 2
= 4.5 moles of Cl₂
2.
Mole ratio of C₃H₈ to CO₂ is 1 : 3.
Hence, 0.5 moles of C₃H₈ will produce 1.5 moles of CO₂.
Also,
At STP one mole of an ideal gas occupied 22.4 L of volume. Hence, 1.5 moles of CO₂ gas will occupy,
Volume = 1.5 mol × 22.4 L/mol
Volume = 33.6 L of CO₂
