The cerebrum is part of the brain that controls the functions of the voluntary activity in the body. If an organism is smaller than another organism, for this case a frog and a rabbit. It means that the frog and the processes inside that body are less complex. Thus, the cerebrum do not need to be bigger than the cerebrum of a bigger organism.
A chemical reaction is the process by which a ___ takes place
A chemical reaction is the process by which a change takes place
A chemical reaction is a process by which one or more substances, called reactants, are transformed into one or more other substances with different properties, called products.
The bonds between the atoms that make up the reactants are broken. Then, the atoms rearrange themselves in another way, forming new bonds and giving rise to one or more different substances from the initial ones. So the atoms do not change, they remain the same, but it changes is the way they are linked together.
In short, chemical reactions are the process of arranging atoms and bonds when chemicals come into contact. The chemical properties change by altering the arrangement of the atoms in that substance.
So, a chemical reaction is the process by which a change takes place.
A chemical reaction is the process by which a CHANGE takes place (?)
What’s the difference between the three scales used to measure seismic waves
Potassium has an atomic number of 19.Which of a potassium atom's electrons are its valence electrons? Select one: a. Those in the third shell from the nucleus. b. Those in the second shell from the nucleus. c. Those in the outermost shell. d. Those in the innermost shell.
The correct response would be C. Those in the outermost shell, and of highest electron energy are the valence electrons for potassium.
Animals can change the energy in food into energy the animals can use. What type of energy is in the food before the animals change it?
Oil and natural gas were formed from sea creatures. The energy stored in the fossil fuels originally came from sunlight. Plants used light energy from the Sun for photosynthesis to make their chemicals. This stored chemical energy was transferred to stored chemical energy in animals that ate the plants.
(Fill in the blanks)The movement of water into and out of cells is very _____. Cells need water to ____ properly.
Hope this helps!
Why is an oxygen molecule more stable than and oxygen atom ?
The diatomic oxygen has been more stable than the atom of oxygen due to the presence of a covalent bond.
The oxygen has been the nonmetal with 6 valence electrons. In order to attain a stable configuration, oxygen has to gain 2 electrons.
The elemental oxygen present in nature has been diatomic oxygen. The diatomic oxygen has been formed by the sharing of the 2 electrons of each atom resulting in the formation of the covalent bond.
The covalent bond formation helps the oxygen atom to attain the noble gas configuration. Thus, diatomic oxygen has been more stable than atomic oxygen.
