This piece of equipment is used to measure the volume of a liquid with high precision in a laboratory.
What is a graduated cylinder?
A chemical reaction that releases heat is known as this type of reaction.
What is an exothermic reaction?
In a neutralization reaction, an acid reacts with this type of substance to produce water and a salt.
What is a base?
Found in many homes, this substance with the formula NaClO is used for whitening clothes and disinfecting surfaces but can release toxic gases if mixed with acids.
What is bleach?
The seeds of this plant, Ricinus communis, contain ricin, a highly potent toxin.
What is the castor bean plant?
In the lab, this term refers to the process of separating a solid from a liquid by pouring the mixture through a porous material.
What is filtration?
When iron reacts with oxygen and water, it forms this common reddish-brown compound.
What is rust (iron(III) oxide)?
This process involves separating the components of a mixture based on differences in their boiling points.
What is distillation?
This heavy metal, historically used in paints and pipes, can cause neurological damage, especially in children, upon exposure.
What is lead?
This marine creature, Hapalochlaena, is small but carries venom that can cause paralysis and is recognized by its vibrant blue rings.
What is the blue-ringed octopus?
This technique is used to separate and analyze components of a mixture based on their movement through a medium under the influence of a solvent
What is chromatography?
Toxic substances can enter the body through ingestion, inhalation, or this third method, which occurs through the skin.
What is absorption?
The pH scale measures the concentration of these ions in a solution.
What are hydrogen ions (H⁺)?
Often found in thermometers, this liquid metal is toxic and can vaporize at room temperature, posing inhalation risks.
What is mercury?
Ingesting berries from this plant, Atropa belladonna, can be fatal due to its atropine content.
Ingesting berries from this plant, Atropa belladonna, can be fatal due to its atropine content.
When working with acids and bases, scientists often use this dye-based method to determine pH levels.
What is an indicator?
This category of poisons, which includes cyanide, blocks cells from using oxygen, leading to suffocation at a cellular level.
What are asphyxiants?
This law states that mass is neither created nor destroyed during a chemical reaction.
What is the Law of Conservation of Mass?
This toxic element, symbol As, can contaminate groundwater and is known for its use in pesticides and wood preservatives.
What is arsenic?
This arachnid, Latrodectus mactans, is identified by a red hourglass marking and delivers venom that affects the nervous system.
What is the black widow spider?
This crucial piece of lab safety equipment should be used immediately if a chemical is spilled on a large area of your body.
What is a safety shower?
This mathematical equation, used in kinetics, describes the speed of a chemical reaction based on the concentration of reactants.
What is the rate law?
