Answer;
D. carbon-12 atom
Explanation;
-One atomic mass unit is the mass that is exactly equal to one-twelfth the mass of one carbon-12 atom. Therefore, the mass of carbon-12 is 12 amu and this provides the standard that is used in measuring the atomic mass of all other elements.
-The atomic mass of carbon is 12.01 and not 12.00 in the periodic table.
-Due to the fact that there are more than one element for most naturally occurring elements, the average mass of the naturally occurring mixture of isotopes is taken while determining the atomic mass of an element.
ANSWER - AEGHNZ (is that right?
Answer:
The correct answer is cancer therapy, genetic engineering, and detecting thyroid malfunction.
Explanation:
There are numerous applications of radiation in medicine. The most well-known is the use of X-rays. Other than that radiations are also used in the treatment of cancer known as cancer therapy. It is also used in nuclear medicine therapy like the application of radioactive iodine in the treatment of thyroid issues like thyroid cancer. Radiation also has an application in genetic engineering that comprises the production of modifications in the hereditary units of prevailing animals and plants.
6.6 g
Explanation:
The mole ration between CaCO₃and CO₂ is 1 : 1
Because the molar mass of CaCO₃ is 100.0869 g/mol the amount of moles used in this chemical reaction is;
15/ 100
This will be similar to the moles of CO₂
Because the molar mass of CO₂ is 44g, then well multiply by the moles;
15/100 * 44
= 6.6 g
The independent variable is the one factor you manipulate or change in the experiment.
The dependent is what you are measuring. The independent is the one thing you are altering so you can carry out your experiment.
