Mixtures and Solutions
A solution is this type of mixture, because the two substances mix.
What is a Homogeneous Mixture?
A compound that reacts with metals and carbonates, tastes sour, and turns blue indicator red.
What is an acid?
This is a scale of 0-14 which is the level of acidity or alkalinity of a compound.
What is the potential of hydrogen (pH)?
A change that alters the appearance, but not the chemical makeup of a substance.
What is a physical change?
This reaction produces hydrogen and oxygen by running electricity through water.
What is decomposition?
These are the two types of heterogeneous mixtures.
What are colloids and suspensions?
A compound that feels slippery, tastes bitter, and turns red indicators blue.
What is a base?
These compounds produce positive hydrogen ions (H+) and have a pH from 0-6.
What are acids?
A change that alters the chemical makeup of a substance?
What is a chemical change?
Model the reaction of methane and oxygen.
What is CH4+2 O2>CO2+2H2O?
This is a heterogeneous mixture where particles do not settle out if undisturbed.
What is a colloid?
A compound that doesn’t react with metals and carbonates, tastes normal, and turns red and blue indicators green.
What is a neutral substance?
These compounds produce negative hydroxide ions and have a pH from 8-14.
What are bases?
A chemical reaction that releases energy.
What is an exothermic reaction?
This French chemist made the law of conservation of mass, the principle that matter is not created nor destroyed by any chemical or physical change.
Who is Antoine Lavoisier?
This a heterogeneous mixture that can easily separate.
What is a suspension?
This acid is found in stomachs.
What is hydrochloric acid?
The process by which acids and bases form a salt and a neutral substance, by changing the pH to 7.
What is a neutralization?
A chemical reaction that absorbs energy?
What is an endothermic reaction?
The reaction where two or more compounds form new compounds without forming elements.
What is replacement?
The ability for a solute to dissolve in a solvent.
What is solubility.
This acid is found in skeletal muscles.
What is lactic acid (C3H6O3)?
Model the reaction between magnesium hydroxide and hydrochloric acid.
What is 2 HCl+Ca(OH)2>2 H2O+CaCl2
This makes baking food an endothermic reaction.
What is it burns when it absorbs heat?
The reaction where two or more elements form compounds?
What is synthesis?
