3. A student performed the following reaction in the lab:
2Mg + O2 → 2MgO
She isolated 25.8g of MgO. She also knew how to calculated the expected or the theoretical yield based on the amount of her starting materials (She was of course one of Dr. W’s prize students). She calculated the theoretical yield to be 28.9g.
What was the % yield for this experiment?

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
