Explanation:
Answer:
Explanation:
Hello!
In this case, since the molarity of a solution is computed by dividing the moles of solute by the volume of solution in liters, we first need to compute the moles of solute knowing that the molar mass of calcium hydroxide is 74.1 g/mol as follows:
Next, since the 100-mL solution is also expressed in liters by 0.100 L, we directly compute the molarity as shown below:
Which is expressed in molar units that are mol/L.
Best regards!
Calculations in chemistry can range from large numbers to the smallest number in decimals to be more accurate in data results. When this occurs using scientific notations allows you to note down results regardless of size as accurate as possible without writing a lot of numbers.
Answer:
C. freezing
Explanation:
Point B is right at the border between a solid and a liquid so you can have two physical changes:
a) solid is <u>meting</u> to transform into a liquid
or
b) liquid is <u>freezing</u> to transform into a solid (C)
If you are on the border between a solid and a gas you have the following physical changes:
solid to gas - sublimation
gas to solid - deposition
If you are on the border between a liquid and a gas you have the following physical changes:
liquid to gas - boiling
gas to liquid - condensation
