Since the reaction gives off heat energy it is considered to be an exothermic reaction
The hole in the boat caused it to take on water, as the boat filled with water, it became less and less buoyant, eventually filling with water until losing buoyancy completely and sinking.
A is correct because the fruit salad can be easily separated and the puch cannot so it is a solution and the fruit salad is a mixture.
Answer:
Decomposition Reaction
2 AgCO₃ -----> 2 Ag + 2 C + 3 O₂
Explanation:
During the reaction, the reactant breaks down into smaller elements/compounds. As such, this is a decomposition reaction.
An equation is balanced when there is an equal amount of each element on both sides of the reaction. If these amounts are unequal, you can add coefficients to modify the quantities of particular elements/compounds. These coefficients must be as small as they can be while remaining whole numbers.
The unbalanced equation:
AgCO₃ -----> Ag + C + O₂
<u>Reactants</u>: 1 silver, 1 carbon, 3 oxygen
<u>Products</u>: 1 silver, 1 carbon, 2 oxygen
The balanced equation:
2 AgCO₃ -----> 2 Ag + 2 C + 3 O₂
<u>Reactants</u>: 2 silver, 2 carbon, 6 oxygen
<u>Products</u>: 2 silver, 2 carbon, 6 oxygen
