Scientists can reflect on the elements that are already there and predict the next ones
Answer:
<u>~</u><u>Law of Conservation of </u><u>energy~</u>
The law of conservation of energy states that energy can neither be created nor destroyed, only energy can be converted from one form to another.
Answer:
An area around a molecule that describes a region of space where the electrons that are shared between bonded atoms can reside
Explanation:
A molecular orbital is an area around a molecule that describes a region of space where the electrons that are shared between bonded atoms can reside.
Molecular orbitals are formed by linear combination of atomic orbitals of about the same energy. The number of atomic orbitals that are combined to give molecular orbitals is the same as the number of molecular orbitals formed. The build up of electrons in molecular orbitals also follow the Aufbau principle, Hund's rule and Pauli exclusion principle.
Solution:
mass of the cellulose in the mixture is 0.38g
total mass of the mixture is:
3.35+0.38+8.76
=12.4g
thus the percentage of the cellulose in the mixture is:
mass of the cellulose/total mass of the mixture*100%
0.38/12.4*100%
=3%
