B. The lines show where a phase change happens to a substance
The answers is 260mph In 4 hours
Answer:
The Lewis structure of CH3OCH3 is dimethyl ether, the simplest ether in existence
Explanation:
false
Explanation:
no because there is 2 hydrogen and 2 oxygen
that would be hydrogen peroxide but water is H2O
Answer:
When atoms bond together to form compounds, they attain lower energies. The difference between energies of the bonded atoms and individual atoms is released in this case.
Similarly, when the compounds, like water, are broken, energy is absorbed, and the resultant atoms have higher energy.
2H₂O ⇒ 2H₂ + O₂
The energy required to break this bond is known as bond energy.
For example in the given reaction, 469kJ/mol is the bond energy absorbed to carry out the reaction.
