Answer:
Combination reaction
Explanation:
In Chemistry, elements and compounds are involved in a process called chemical reactions, which are of different types namely: combination, decomposition, double replacement, combustion etc. A combination reaction is that reaction in which two or more substances called the REACTANTS combine together to form a single new substance called the PRODUCT.
In this case, a reaction is depicted as follows:
2SO2(g) + O2(g) --> 2SO3(g)
In this reaction, compound SO2 combines chemically with element O2 to form a single new compound SO3. Hence, this is a type of COMBINATION REACTION.
In order to calculate for the amount of CaCl2 and water used we need to multiply the total amount mixture to the percentage of each component. Since we are given a two component mixture CaCl2-water with 40% CaCl2 by mass, therefore we have 60% water.
Amount of CaCl2 = 0.40*(370.9) =148.36 g of CaCl2
Amount of Water = 0.60*(370.9) = 222.54 g of Water
Molecules are made of atoms. Cells are made by a multitude of molecules. ... So cells are made of molecules and, consequently of atoms .
