QUESTIONS FOR RESEARCH
1. Matter is any material that has mass and occupies space, including atoms and anything created from atoms.
While energy in science is used to explain how much a physical system has the capacity to change. Energy is a
characteristic of matter in physics. It may be transported between items and transformed into a different shape.
2. An element is a pure material made up of atoms with the same amount of protons in their nuclei while a
compound is a chemical substance made up of several similar molecules made up of atoms from many elements
bound together by chemical bonds. Examples of elements are carbon, oxygen, iodine, and calcium. For the
compound are carbon dioxide, nitric acid, ethane, acetic acid, and sodium carbonate.
3.
IONIC BONDS SIMILARITIES COVALENT BONDS
It is a complete transfer of
electrons between two atoms that
results in separate positively
charged and negatively charged
ions.
Both of these leads to the creation
of stable molecules.
It results when a pair of electrons
are shared between atoms with
similar electronegativities. It is also
an unequal sharing of electron
pairs.
4.
Acid Base Salt
Acids are proton donors. Bases are proton acceptors. These are formed when an acid
reacts with a base.
5. Because it is essential for understanding anatomy and physiology and also it helps us to determine which or
what chemicals are we going to use to make our body function properly.
6. It results in an increase of
H+¿¿
and a decrease in pH. But if it’s a buffered solution, the buffer binds to the
H+¿¿
,
and prevents from causing a decrease in the pH of the solution.
7. Because making bread has a much stronger aroma and the scent of ice cream is also much reduced because it is
frozen, implying that the molecules that make up the ice cream are far more confined.
8. Because muscle contains proteins and the energy is derived from the potential energy held in the chemical
bonds of food molecules, which is released during food breakdown.
9. A small quantity of heat acts as activation energy, initiating a chemical process. The reaction generates a lot of
heat, which causes the solution to get heated.
10. Because cellular processes require ATP. It is used to utilize and construct the organic molecules required by cells
and tissues. It also supplies energy for muscular contraction and electrical signal transmission in the neurological
system.
11. Because plants provide the oxygen that mammals breathe. Plants use photosynthesis to obtain energy from the
sun, carbon dioxide from the atmosphere, and water and minerals from the soil. Then they expel water and
oxygen. Animals then employ an oxygen-based mechanism known as respiration. Respiration is the process
through which organisms get energy from food, and carbon dioxide is released.
