Explanation:
the molar mass of a compound can be caucaleted by adding the standar atomic masses.
In the equation given above, there is conservation of MASS, CHARGE AND ENERGY.
These three parameters are usually conserved during the course of chemical reactions. When any of these parameter experience a reduction during the course of chemical reaction, such loss is always gained by other elements involved in the same reaction, so that at the end of the day, they are not considered as lost.
Answer:
A. Engineers come up with scientific questions when they are developing their design, and scientists do research to answer them.
