Lab Safety
This safety equipment is used if a chemical has splashed into your eyes.
What is safety goggles?
Define a covalent bond
A type of bond that occurs when non-metals share electrons
In a laboratory investigation, what evidence might indicate that a combustion reaction is occuring?
Production of fire (light, heat, sound)
This is the location of the fire extinguisher & fire blanket in the classroom.
What is at the front by the door?
A type of bond that occurs whem metals (or hydrogen) transfers electrons to a non-metal
What are the reactants in a complete combustion reaction?
Hydrocarbon + excess oxygen
This hazard is associated with the GHS symbol that has a picture of a fish
What is hazardous to the aquatic environment?
This type of compound is most likely to be soluble in water
What is an ionic compound or a polar molecular compound?
What are the products in a complete combustion reaction?
Carbon dioxide + water vapour
These are 2 pieces of safety equipment that you would use AFTER an accident occurs.
What are fire extinguisher, fire blanket, and/or eyewash station?
Define melting point
The temperature at which a subtance melts (from solid to liquid)
What are the reactants of an incomplete combustion reaction?
Hydrocarbon + lack of oxygen
This GHS symbol could be used for carbon monoxide
What is acute toxicity?
Why do ionic compounds have higher melting points than molecular compounds?
Ionic compounds have strong attractive forces due to the positive and negatively charged ends
What are the products of an incomplete combustion reaction?
Carbon dioxide, water vapour, carbon monoxide, soot
