Matter Test Flashcards
- which of the following is not a physical property?
answer=
D. reactivity with oxegyn
notes
- what are three examples of a physical change?
answer=
B. boiling water, blowing up a balloon, and melting a candle.
u2 c1 notes
- what is matter in at which the particles are free to move in all directions until they have spread out evenly through their container.
answer=
C. gas
notes
- what is a solution that contains all of the solute I can normally hold at a given temperature.
answer=
A. saturated
- what is a flask containing molecules of gas a in a separate flash contain molecules of gas be both at the same temperature
answer=
D. average kinetic energies
- how are particles in a liquid usually put together
answer=
D. They are closer together in lower and energy than in a gas
- using the data to the right determine the identity of a cube of metal that measures 1.2 cm on each side and has a mass of 18.15 g
answer=
B. Silver
- A solution that contains more of the solid then I can normally hold out a given temperature
answer=
C. Super saturated
- The law of conservation of mass states what
answer=
D. Mass is not lost or created during a chemical change
- it’s salt water heterogeneous make sure homogeneous
answer=
homogeneous
- how many grams of sodium chlorate or needed to make a saturated solution and 100 g of water at 90°C
answer=
180 g
- in terms of saturation how would you classify potassium bromide solution with a concentration of 90 g and 100 g of water at 10°C
answer=
Super saturated
- in terms of saturation how would you classify a potassium nitrate solution of 30 g in 100 g of water at 40°C
answer=
unsaturated
- what is the solubility of which salt is the least affected by temperature
answer=
Salt/sodium chloride
- I am in action react to form with us. What what happened to the mass of the razz compared to the mass of the yard and auction before the reaction? Explain why this occur
answer=
same because the law of conservation of mass says matter cannot be created or destroyed even in a chemical change
List and explain the three factors that increase the solubility rate of a substance
answer
smaller solid size has more surface area, and higher temperature because more particles collide, more stirring because it brings fresh solvent in contact with solute
- name one similarity between compound and homogeneous mixture is in one difference
answer=
they are like because both need one element and they are difference because compound is chemically combined and a mixture is physically combined
- Explain how salt dissolves in water
answer=
The attractive force pulls ions away from crystals in the water surround each ion and continues until all Ions separated
