The empirical formula is CH2O bc you divide the percent and the mass of the element, Carbon 40/12.01=3.33, Hydrogen 6.7/1.01=6.63, Oxygen 53.3/16.00=3.33, then divide the lowest number which is 3.33 to all Carbon 3.33/3.33=1, Hydrogen 6.63/3.33=1.99 but rounds to 2, Oxygen 3.33/3.33=1
The products and reactants weigh the same since u have to balance out the equation to have an equal number of molecules on bothsides

The stream that flows during or after the rainfall is called an ephemeral stream. This stream occurs in areas where there is less rainfall or deficiency of moisture.
The stream that flows only in flat lands is called as river.
Mechanical weathering results in the breaking of rocks causes ice wedging.
Chemical weathering results in the change in molecular structure of rocks and soil.
Thus, it can be concluded that option (a) is the correct answer.
