I WILL GIVE BRAINLIEST PLEASE DO IT RIGHT!!! 1) Using the data below, create two simple line graphs on a separate sheet of paper

that will help you to determine the type of reaction. Your graphs should have the independent variable on the y-axis (temperature) and the dependent variable on the x-axis (time). Because we did not measure the time in the same intervals, you should do two separate graphs rather than a combined one. You must determine the correct spacing for your axis and the scale. Make sure that the graphs are labeled correctly and are titled.
2) How can you tell from your graphs which reaction was endothermic and which one was exothermic?

Classify each of these reactions. A single reaction may fit more than one classification. Ba ( ClO 3 ) 2 ⟶ BaCl 2 + 3 O 2 Ba(ClO
Vilka [71]

Answer: a) Ba(ClO_3)_2\rightarrow BaCl_2+3O_2:  Decomposition

b) NaNO_2+HCl\rightarrow NaCl+HNO_2: double displacement

c) CaO+CO_2\rightarrow CaCO_3: Synthesis (Combination)

d) ZnSO_4+Mg\rightarrow MgSO_4+Zn: redox

Explanation:

Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.

Ba(ClO_3)_2\rightarrow BaCl_2+3O_2

A double displacement reaction is one in which exchange of ions take place.

NaNO_2+HCl\rightarrow NaCl+HNO_2

Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.

CaO+CO_2\rightarrow CaCO_3

Redox reaction is a type of chemical reaction in which oxidation and reduction takes place in one single reaction. The oxidation number of one element increases and the oxidation number of other element decreases.

ZnSO_4+Mg\rightarrow MgSO_4+Zn
