Answer:
- 100g
- 1.000.000mg
- 10 kg
Explanation:
1.000.000mg = 1,000 g =1kg
100g =.01kg
10 kg
One of them oxygen or chlorine, the reason is that from the left to the right the electronegativity increases as well from the bottom to the top it increases as well :)) so the chlorine and oxygen is near each other so i cant decide cuz im not sure ☹️☹️

Hey there.. the question is not proper. Please give the whole question
Answer:
Mass of mercury produced = 2.00 g
Explanation:
At room temperature and pressure, the temperature T = 25° C or 298.15 K while the pressure = 1 atmosphere or 760 mmHg.
Mass of oxide of mercury decomposed at room temperature and pressure = 2.16 g
Volume of oxygen produced = 120 cm³ or 0.12 dm³
One mole of any gas has a volume of 24 dm³ at room temperature and pressure.
Therefore, number of moles of oxygen produced = 0.12 dm³ / 24 dm³/mol = 0.005 moles
Mass of oxygen produced = number of moles × molar mass
Molar mass of oxygen = 32 g/mol
Mass of oxygen produced = 0.005 moles × 32 g/mol = 0.16 g
Thus, mass of mercury produced = mass of mercury oxide decomposed - mass of oxygen produced
Mass of mercury produced = 2.16 g - 0.16 g
Mass of mercury produced = 2.00 g
