It's answer is c. N2
The maximum bond energy is of N2 because N2 molecule is formed by 3 covalent bonds and O2 molecule is formed by 2 covalent bonds.
Hope it helps :)
There are six common types of reactions:
1. Combination
2. Decomposition
3. Single Displacement
4. Double Displacement
5. Combustion
6. Redox
The reaction: SO₃₍g₎ + H₂O₍l₎ → H₂SO₄₍aq₎ is classified as a combination reaction. This is because for combination reactions, two (or more) reactants form a single product. On the other hand, decomposition reactions involve a single reactant breaking down into two or more simpler substances. Displacement reactions involve a more active element displacing a less active element from a compound. Meanwhile, combustion reactions involve a carbon-containing compound reacting with oxygen to form carbon dioxide and water. Redox reactions then involve exchange of electrons between species.
D is true because sulfur is a gas sooooooo
Answer: 2 electrons
Explanation: Good luck! :D
Answer:
The water of crystallization for the formula of the unknown hydrate is 2.
Explanation:
Mass of an unknown hydrate = 1.000 g
Molar mass of hydrate = 195.5 g/mol
MOles of unknown hydrate =
Mass of hydrate after heating = 0.781 g
Mass of water lost due to heating = x
Moles of water lost =
1 Mole of hydrate has x moles of water and 0.00512 moles of hydrate has 0.0122 moles of water then we can write:
The water of crystallization for the formula of the unknown hydrate is 2.
