Answer:
32 million Americans are exposed to toxic chemicals in the workplace regularly. CERTAIN HAZARDOUS CHEMICALS ARE CONSIDERED TO BE ONE OF THE MAJOR CAUSES OF BIRTH DEFECTS. When these workers use harmful chemicals, those toxins can be absorbed through the skin, inhaled or ingested by the mother or the father before or during pregnancy. That can affect the parents’ ability to have healthy children. They may have issues having children or may have children with birth defects. These types of chemicals that cause birth defects are known as teratogen and/or genotoxins. A teratogen is an agent that interferes with the development of an embryo or fetus and causes birth defects. A genotoxin is an agent that damages cellular DNA resulting in mutations. Chemicals can be both a teratogen and a genotoxin. Industries with workers who are most at risk of being exposed to toxic chemicals include high-tech manufacturing and semiconductor manufacturing, agricultural and farming, and energy production workers in coal, fracking, and oil and gas. These laborers are commonly exposed to toxins in chemicals, solvents, and pesticides and heavy metals — all chemicals known to cause birth defects.
a. They are both normally found as gases in the atmosphere. TRUE
That is correct, the oxygen and nitrogen are found in large quantities in the air around us.
b. They can be either liquids or gases. TRUE
Under certain temperatures any gas will transform into a liquid.
c.They turn from gas to liquid at the same temperature. FALSE
Oxygen it will pass into a liquid at -183 °C while nitrogen pass into a liquid at -195.8 °C.
d.They can be changed from gases to liquids by heating them. FALSE
The gases change to liquids by cooling them.
All nuclear chemistry revolves around changing the identity of base elements.
The answer is the third statement.
Because nuclear chemistry is changing base elements' identities, the atomic number/number of protons is what is changing. While the number of electrons can change, your question is too general to know whether electrons are going to be gained, lost, or retained in the reaction.
Answer:
Demonstrate familiarity with the pH scale ... body (excluding things like stomach acid) measure around 7.2 and 7.6 on the pH scale (a 7 is neutral on the scale). ... The pH of a solution is a measure of its acidity or alkalinity (base). ... Using a pH meter, you find the pH of an unknown solution to be 8.0.
Explanation:
A) it is a solid because strong attractive forces prevent particles from moving.
