SO2 + O2 ---> SO3. Moles of SO2 = 0.64/32+16X2 = 0.01mole. According to stoichiometry, moles of SO2 = moles of O2 = 0.01mol. Therefore volume of oxygen gas at STP = 22.4 x moles of O2 = 22.4 x 0.01 = 0.224 = 224mL.
It's because of the landscape, it changes over time.
Answer:
The answer to your question is Aluminum
Explanation:
Number of clues
1.- If this element has 3 rings in its Bohr model, we are looking for and element located in the third period of the periodic table.
For example Sodium, Magnesium, Aluminum, Silicate, Phosphorus, Sulfur, Chlorine and, Argon.
2.- It makes three bonds to become stable, then we are looking for and element located in the third group like
Boron, Aluminum, Gallium, Indium, etc
Conclusion
The element that has both characteristics is Aluminum
Answer:
Protons and electrons
Explanation:
They have a different number of neutrons giving them a different atomic weight while having the same charge
