Answer: Because sulfur is directly below oxygen in the periodic table, these elements have similar electron configurations. As a result, sulfur forms many compounds that are analogs of oxygen compounds, as shown in the table below. ... O=O. double bonds are much stronger than S=S double bonds.
Answer:
1.6 mol Carbon Dioxide
Explanation:
In order to convert between mols of compounds, you need to use the mole ratio. First, divide 2.5 moles of oxygen gas by 8 moles of oxygen because that is the number of moles of oxygen gas in the balanced equation. Then to find the number of moles of carbon dioxide, multiply by the 5 moles of carbon dioxide in the mole ratio. After multiplying, you get the answer 1.56 moles of carbon dioxide and with 2 significant figures present you would round to 1.6 moles.
Answer: 10.7 moles
Explanation: Hydrogen gas exists as a diatomic gas (H2) Hence, the Molar mass of one mole of hydrogen gas is 1 x 2 = 2 g. To find the number of moles from the mass take the weight and divide is by the molar mass of the molecule. So in this case, 21.4/2 = 10.7 moles
