How do I calculate question 1 part b (in the picture)? I don’t even know where to start.    Thank you!

4. A 100 mL solution was prepared by dissolving 10.00 g of CaSO4 (MW= 136. 14 g/mol) in water. The density of the solution was found to be 1.15 g/ml at 25 C. Find the new boiling and freezing temperature of water in this solution. Answers in 2 decimal places. no need to write the unit. New boiling point = [A] %3D New Freezing point = [B]

Solid particles in water may exist in 3 ways - dissolved, dispersed, or suspended. (True/False) When a previously dissolved solid separates from water either via chemical reaction or a change in certain condition like pH or temperature, it forms a______.

Please send me the question in 20 minutes it's very urgent plz both 1 and 2

Fill in the blanks please

hello can you plz help me plzzz

3. Standard white vinegar you can buy in the grocery store is 5% concentration. That means 5% of the liquid vinegar is acetic acid and 95% of the solution is water. In a hardware store, you can buy industrial strength vinegar, which is 30% concentration. This means that 30% of the vinegar is acetic acid, and the remaining 70% is water. Samuel does another experiment, this time with 5% vinegar and 30% vinegar. He sets up two science fair volcanoes (in no particular order), each with the same temperature, mass of baking soda and volume of vinegar. But one volcano uses 5% vinegar and the other volcano uses 30% vinegar. He measures the volume of gas production for the first minute of each reaction, and he records the data below. Volcano # 1 Volume of gas Volume of gas produced (mL) vs. Time (s) for Volcano #1 Time (s) produced (mL) 60 E 50 10 25 40 20 38 30 46 30 • Volume of gas produced (mL) 40 50 50 52 10 60 53 20 40 60 80 Time (s) Volcano # 2 Volume of gas produced (mL) vs. Time (s) for…

What is the answer of this?

Video: Experiment #11: Molar Mass Determination by Freezing Point Depression - SMU Chemistry   In the video, the temperature of the acetic acid solution was measured over time.  Using excel or google sheets plot the data from the video (reproduce the graph below) Make sure to include: -A title -x and y axis values and titles -A descriptive legend (the thing that identifies which line means what) -The y-axis should read between 11 and 17 C -The x-axis should be between 0 and 400 seconds

50 mL of stock solution were taken and added to flask. Then 50 mL of Di water were added to the flask. This is solution 1. Then 50mL of solution 1 were taken and added to a flask and 50 mL of Di water were added to the flask. This is solution 2. Then 50mL of solution 2 were taken and added to a flask and 50 mL of Di water were added to the flask. This is solution 3. Then 50mL of solution 3 were taken and added to a flask and 50 mL of Di water were added to the flask. This is solution 4. Find the concetrations of each solution.  Information of stock solution - molar mass- 534.3g/mole 0.587g in MilliQ

Mikaela is a STEM student who is currently having her General Chemistry 2 subject.Today, she is asked by her teacher to prepare a CuSO4 solution. Help her do her task byfollowing the procedure and answering the question below.1. Obtain a sample of CuSO4 from the front bench.2. Using your scale, weigh out 18g of CuSO4.3. Dissolve the 18g of CuSO4 in 100 mL of distilled water.4. Stir until you have reached a homogeneous solution with all the solute dissolvedin the solvent.Calculate the concentration of your solution (M in mol/ L of CuSO4). Show your workin the space provided below.
