A mole is a counting unit for very large numbers of things.
What is mole?
100
Matter is anything that has mass and occupies volume.
What is matter?
100
Its an equation to find out volume, pressure, the mole, and the temperature.
What is pv=nRt?
100
Add more water.
How do you dilute an acid?
100
It burns and stings!
What does acid do to your skin?
200
4.32mol AL
How many moled of AL are in 2.16 mol of Al2O3?
200
Four.
How many states are in matter?
200
The balloon will heat up, temperature will increase, and it will expand.
If a balloon is left in a closed car on a hot day, what will happen to it?
200
One that contains a large amount of solute.
What is concentration solution?
200
A substance that generates hydronium ions, h3o+, when added to water.
What is Acid?
300
9.96 x 10-19 moles of copper
How many moles of copper are in 6,000,000 atoms of copper?
300
solid, liquid, gas, and plasma.
What are the four states in matter?
300
The gas would have a volume of 0L
What would the volume of any gas be at absolute zero?
300
Saturated solution contains all the dissolved solute. Unsaturated doesn't contain all the dissolved solute.
What are the differences between saturated and unsaturated?
300
Bitter taste, feel slippery on your finger, bases turn litmus from red to blue, and react with acids!
What are the characteristics of bases?
400
90 moles
How many moles of oxygen are in 2.71 x 1025 molecules of carbon dioxide (CO2)
400
Gravity!
If gases will spread out indefinitely when unconstrained, what keeps the air in our atmosphere from spreading out into space?
400
The gas particles exert a force on a surface when they bounce off it, thus creating pressure.
What causes gas pressure?
400
An unstable heterogeneous liquid mixture.
What is a suspension?
400
A solution with a significant concentration of H3O+ ions.
What is acidic solution?
500
0.0725mol N2 and 0.218 H2
How many moles of H2 and N2 can be formed by the decomposition of 0.145 mol of ammonia(NH3)
500
Superfluids, Fermionic, Condensates, and Rydberg Molecules
What are the other states of matter in extreme conditions?
500
Absolute zero is the coldest possible temperature that can exist anywhere
What is absolute zero?
500
Stirring/agitation, changing the surface area of the solute, change in temperature.
What can change solubility?
500
Yes b/c once you used up the PbO2 the PbSO4 2H2O uses the energy to rebuild the PbO2
Is this a reversible chemical reaction Pb(s) + PbO2(s) + 2H2SO4 ←→ 2 PbSO4(s) + 2H2O(l) + energy? explain why
