Answer:
Water is polar covalent while isoporopanol is covalent
Explanation:
Water contains polar covalent bonds. Water has a high dipole moment and thus dissolves ionic substances easily such as sodium chloride. Water is also a good electrolyte. Water is not volatile. Water molecules are held together by hydrogen bonds. Isopropanol is a covalent compound. It is non polar and suitable for dissolving non polar substances such as campohor. It is volatile but dissolves in water due the the -OH group present in the molecule.
Answer:
0.631 grams is the theoretical yield of solid copper (Cu) that can be recovered at the end of the experiment
Explanation:
The concentration of the solution is given by :
We have:
Concentration of copper (II) nitrate solution =
The volume of solution = 4.12 mL
1 mL= 0.001 L
Moles of copper (II) nitrate in solution = n
Moles of copper (II) nitrate in solution = 0.0099292 mol
1 Mole of copper(II) nitrate has 1 mole of copper then 0.0099292 moles of copper(II) nitrate will have :
Mass of 0.0099292 moles of copper:
This mass of copper present in the solution is the theoretical mass of copper present in the given copper(II) nitrate solution.
0.631 grams is the theoretical yield of solid copper (Cu) that can be recovered at the end of the experiment
Explanation: The insoluble magnesium carbonate produced is called a precipitate. In a double displacement reaction, ionic compounds combines to produce precipitates. In this type of reaction, species are usually exchange to form new compounds
Explain: parapet ma
The best design for this experiment is to number the items from 1 to 1,200 and then choose random numbers in the table of random digits (second option).
<h3>How to use a table of random digits?</h3>
These tables are used to randomly assign items or subjects into groups when experimenting. The best way to use these tables are:
- Give each item or participant a number.
- Take a lot at the table and choose a number.
- If this number is the same that the number assigned to an item or participant classify it in the first group.
- Keep selecting.
Based on this, for this experiment the steps are:
- Number the items from 1 to 1,200.
- Identify numvers in the table.
- Assign the first 400 items to the process 1 group.
- Repeat the process for the other two groups.
