Conservation of Mass Flashcards
what is the letter that stands for density
p
what is the equation for density
p = mass/ volume
what is the unit for density
kg/ m cubed
what is the unit for volume
m cubed
what is the unit for mass
kg
what is the equation for working out the volume of regular objects
volume = length x width x height
what is the way of working out the volume for irregular objects
displacement
describe step 1 of the displacement method
fill displacement cab to top with water
describe step 2 of the displacement method
place object slowly into displacement can
describe step 3 of the displacement method
collect water that is displaced in a measuring cylinder
describe step 4 of the displacement method
measure the volume of water in ml
describe step 5 of the displacement method
convert ml to cm cubed to find volume of object
how many ml makes up 1 cubic cm
1 ml = 1 cm cubed
what is the chemical formula for calcium carbonate
CaCO3
what is the chemical formula for copper carbonate
CuCO3
what is the chemical formula for ammonia
NH3
what is the chemical formula for hydrochloric acid
HCl
what is the chemical formula for sulfuric acid
H2SO4
what is the chemical formula for nitric acid
HNO3
what is the chemical formula for ethanoic acid
CH3COOH
what is the chemical formula for sodium hydroxide
NaOH
what does the arrow mean in a chemical equation
produces
what is the law of conservation of mass
no atoms are created or destroyed during a chemical reaction and the total mass of the reactants equals the total mass of the products
what happens to the products if the reactants is a gas
the product appears to be greater than the reactants because the particles are more spaced out
