100
Follow all instructions carefully. Use special care when you see the word CAUTION.
What word should you use special care for, Science Safety Rules.
100
A material safety data sheet is a technical document which provides detailed and comprehensive information on a controlled product related to health.
What is MSDS
100
a process in which one or more substances, the reactants, are converted to one or more different substances, the products.
What is a Chemical Reaction
100
Common aqueous acids include hydrochloric acid (a solution of hydrogen chloride which is found in gastric acid in the stomach and activates digestive enzymes), acetic acid (vinegar is a dilute aqueous solution of this liquid), sulfuric acid (used in car batteries), and citric acid (found in citrus fruits).
What are examples of an acid.
100
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air.
What causes Acid Rain.
200
Never do laboratory work unless your teacher is supervising you.
What work should you not do, Science Safety Rules.
200
before the three years has elapsed
when should MSDS be updated
200
Combination or Synthesis Reaction. Decomposition Reaction. Displacement or Replacement Reaction. Acid Base Reactions. Combustion Reaction.
What is the 5 types of chemical reactions and examples.
200
Since removing H+ ions from water molecules is one way to increase the OH- ion concentration in a solution, metal hydrides are bases.
How acid is formed.
200
A great way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power.
How can we solve acid rain.
300
NEVER run, push, or engage in horseplay of any kind in the laboratory.
What should you not do in a lad, Science Safety Rules.
300
product must not be more than three years old
can MSDS expire
300
One of the more obvious chemical reactions is the burning of fuels. And when you cook using a gas stove, you're burning natural gas.
What is a chemical reaction that happens in everyday life.
300
An acid is a substance that donates hydrogen ions. Because of this, when an acid is dissolved in water, the balance between hydrogen ions and hydroxide ions is shifted.
What does it mean to be an acid.
300
Acid rain in Scandinavian countries is caused by air pollution in Britain and other countries of Europe.
Where does acid rain happen the most.
400
Always check glassware before you use it. Never use glassware that is chipped or cracked. Show this glassware to your teacher.
What is Science Safety Rules for glassware.
400
because only certain content of the MSDS is specified by law
why should some MSDS`s look different
400
A most likely clue to a chemical change occurs when the process produces a gas, light, smell, a fire or heat, or a color change.
What is an example of a chemical change.
400
Vinegar is diluted acetic acid, which is what gives salad dressings and pickled vegetables their tart taste.
What are examples of acids in everyday life.
400
The harm to people from acid rain is not direct. Walking in acid rain, or even swimming in an acid lake, is no more dangerous than walking or swimming in clean water.
Can acid rain kill you.
500
Always heat liquids slowly and/or cover to avoid spattering.
What is Science Safety Rules hot liquids.
500
Yes employers must make sure that all controlled products have an up-to-date (less than three years old) MSDS when it enters the workplace
As an employer, do I have responsibilities for MSDSs
500
Ability to oxidize - This is what takes place by gaining oxygen, losing hydrogen, or losing electrons, and is a chemical property that results in the oxidation number of a substance being changed.
What is an example of a chemical property.
500
Acids and bases are two types of corrosive substances.
What is the difference between an acid and a base.
500
Reduce amount of sulphur dioxide and oxides of nitrogen released into the atmosphere.
How can we control acid rain.
