The balanced chemical reaction is:

Zn + 2AgNO3 =  Zn(NO3)2 + 2Ag

To determine the amount of the reactant left, we have to determine which is the limiting and the excess reactant. We do as follows:

5.65 g Zn ( 1 mol / 65.38 g) = 0.09 mol Zn
21.6 g AgNO3 (1 mol / 169.87 g) = 0.13 mol AgNO3

The limiting reactant would be silver nitrate since it is consumed completely in the reaction. The excess reactant would be zinc. 

Excess Zinc = 0.09 mol Zn - (0.13 / 2) mol Zn = 0.025 mol Zn left

Carbon and oxygen combine to form carbon dioxide. What are the products, or what is the product, in this chemical reaction?
VladimirAG [237]

The product in this chemical reaction is Carbon Dioxide or CO2.

This is because it states, "To form," which means that it was produced from the reactants Carbon and Oxygen.

To know what the products are in a statement rather than an equation, words such as produced and formed are used.

Hope this helps!

What is the difference between a substance and mixture ?
snow_lady [41]

Explanation:

Matter can be categorized into substances and mixtures.

Matter is anything that has mass and occupies spaces.

Substances are distinct matter with the following properties:

  • All parts are the same throughout i.e homogeneous
  • Their composition is definite
  • They cannot be easily separated or broken down into simpler substances by physical means
  • Separation by physical means is not easy
  • They have a unique set of physical properties.

Mixtures have the following properties:

  • Their composition is indefinite i.e they consist of two or more elements and/or compounds in any proportion by mass
  • Their constituents retains their identity
  • They can easily be separated by physical means
  • They have a broad range of physical properties.
