Mixtures/Compounds
What is the difference between a homogenous mixture and a heterogenous mixture?
Homogenous mixture- a mixture where everything is evenly distributed across
Heterogenous mixture- a mixture where everything is not evenly distributed across.
The process of using the boiling points of water and salt to seperate salt from water. What is that called?
Desalination
What is the equation for the concentration of a mixture?
Mass of solute/ Volume of solution
What is soluibility?
How much solute can dissolve in a solution.
What is the difference between an acid and a base?
An acid produces Hydronium ion( H3O+) while a base produces a Hydroxide ion(OH-). Acids are sour, bases are bitter.
What is the difference between a mixture and a compound?
Mixture- a substance where the contents can be PHYSICALLY separated from each other.
Compound- A substance where the contents can be CHEMICALLY separated from each other.
The process of using the size of a particle to seperate it from water. What is that called?
Filtration
What are the two main ways that we can dilute a mixture?
Take away some solute or add more solvent.
The saturation number for sugar in water is 200g. Give a number that would be unsaturated and another number that would be supersaturated.
unsaturated: x < 200g
supersaturated: x > 200g
What are some real life uses of Acids?
What are some real life uses for bases?
Acids: lemon, lactic acid, sour patch onion, vinegar...
Bases: detergent, soup, sanitizer, bleach...
Which of the following is a mixture?
A. Vinegar
B. Water
C. Salt
D. Sugar
A. Vinegar
There is another process in seperating salt from water. In this one the water evaporates into water vapor. The water vapor travels up to a tube called a condenser which then turns the water vapor back into water( without the salt). What is this process called?
Distillation
France has a mixture that contains sugar and water. There is 30g of sugar and 50ml of solution. What is the concentration of the solution?
0.6g/ml
As you increase the temperature what happens to the solubility of a gas in a liquid?
It decreases.
If a pH strip turns from yellow to red what can we say about the solution?
That it is a acidic solution.
Which of the following is the compound?
A. Milk and cereal
B. Pizza
C. C6H12O6
D. Chipotle Bowl
C. C6H12O6
What are the solute and solvent in a kool aid drink?
Solute : kool aid powder
Solvent: Water
France has another mixture. This time she combines 50ml of milk with 85 mL of water. There is also 45g of sugar. Find the concentration of the solution as a percentage.
0.33g/ml
at 50oC what is the solubility of SO2 in 100g of H2O?
5g
What does a PH of 8 indicate on the scale?
slighty alkaline, basic
What is the specific term name for the vocabulary word substance? Hint: think about rain.
Umbrella term
Why is water called the Universal Solvent?
Because its polar covalent bonds(slightly positive and slightly negative) are able to break down the bonds of solutes( such as salt) into their individual ions, Hydrogen bond
John Has a mixture that is in the shape of a cube. It contains salt and water. There is 25g of salt and one side of the cube is 5cm. What is the concentration of the mixture? Express in units of g/cm3
0.2g/cm3
20g
How many times more acidic is a PH of 2 compared 6
10 thousand times more acidic.
