Consider a hypothetical reaction in which A and B are reactants, and C and D are products. If 26 grams of A completely reacts wi
natali 33 [55]

Answer:

The answer to your question is: 24 grams of D

Explanation:

To answer this question we need to remember the Lavoisier law of conservation of mass, which says that in a chemical reaction matter is neither created nor destroyed.

This means that the amount of matter stays the same.

Then, the reaction is

                    A      +      B      ⇒       C      +      D

                 26 g         12 g             14 g            x

mass                              

of reactants      38 g                              ?          mass of products, but it must be

                                                                          equal to the mass of products

Then                14g + x = 38

                        x = 38 - 14

                        x = 24 g of D

Answer:

This is a chemical change because it has been lit on fire. When it is lit on fire, the fire has been made, heat has been made, and gasses produced from the fire have also been made. Because this introduces new matter to the pictures, it is a chemical reaction.
