Answer:
Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals.
so its false
Molarity is one way of expressing concentration and is equal to the number of moles of the solute per liter of the solution. Therefore,
Molarity = 2.39 mol / L solution
2.39 ( 1.0) = 2.39 mol HF
Hope this answers the question.
Answer:
MgO + H₂
Explanation:
The products of reaction is MgO and hydrogen gas.
This is a single displacement reaction.
In this reaction, the possibility of the reaction is determined by position of the atoms on the activity series.
Mg is higher than H on the activity series, so it is more reactive and it then displaces the hydrogen in water;
Mg + H₂O → MgO + H₂
What are the answer choices?
