Theoretical element “A” has four isotopes. Use the data in the table to calculate the average atomic mass of the unknown element A. All steps of the calculations must be shown for credit.
Isotope Atomic Mass Abundance
A - 49 49.022 amu 89.89%
A - 48 48.031 amu 7.01%
A - 47 48.007 amu 3.00%
A - 46 46.001 amu 0.10%
Answers
From the calculations, the average atomic mass of the element is 48.85.
What is the percentage abundance?The percentage abundance has to do with the amount of an isotope that is available in nature.
Since we have the following mass abundance;
A - 49 49.022 amu 89.89%
A - 48 48.031 amu 7.01%
A - 47 48.007 amu 3.00%
A - 46 46.001 amu 0.10%
The average atomic mass =
(0.8989 * 49.022) + (0.0701 * 48.031 ) + (0.03 * 48.007) + (0.001 * 46.001 )
= 44 + 3.4 + 1.4 + 0.05
= 48.85

Describe Cohesion and Surface tension, and explain how the structure of water is responsible for these properties.
Answers
Answer:
Cohesive forces are responsible for surface tension, a phenomenon that results in the tendency of a liquid’s surface to resist rupture when placed under tension or stress. Water molecules at the surface (at the water-air interface) will form
Adhesion and cohesion are water properties that affect every water molecule on Earth and also the interaction of water molecules with molecules of other substances.
Explanation:
Answer:
A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons.

Answers
Answer:
Prophase, metaphase, anaphase, and telophase.
Explanation:
Mitosis is a type of cell division in which a single mature parent cell is divided into two daughter cells having double number of chromosomes and identical to parent cell. There are four phases of mitosis which are prophase, metaphase, anaphase, and telophase. During prophase phase, chromatin condenses into chromosomes. During prophase phase, the chromosomes of the cell align themselves in the middle of the cell. During prophase phase, During prophase phase, the splitting of chromosomes occur and the separated chromosomes goes to the opposite poles of the cell. During telophase, it results in the production of two nonidentical daughter cells.

Explanation:
Answer:
For example the amazon rainforest is the most biodiverse place on the planet. With deforestation we are putting hundreds of species to extenction and causeing the biodiversity to drop. This causes the whole planet to suffer in many ways such as less oxegen more co2. Some ways we could help eliminate this is to restrict the number of trees to be able to be cut down. This would need to be done by the brazilian government to be able to enforce it.
