Erosion by water and earthquakes
Answer:
I think its a double reaction
Explanation:
n = m/M = 2/18 = 1/9 ~0,1 mol
<span>If thermal energy (heat) must be added to a chemical reaction in order for the reaction to take place, the reaction is endothermic. </span>
Answer:
B
Explanation:
Reactants are the compounds which reaction produce the products. In general terms this can be expressed symbolically as follows:
reactants -> products
Other phenomena like heat are omitted because are not always present, that is, only compounds are included. Therefore, in this reaction the reactants are C3H8 (propane) and O2 ( oxygen) and the products are CO2 (carbon dioxide) and H2O (water)
