Answer:
The correct answer is: 2M Al3+(aq) and 6 M NO3-(aq)
Explanation:
Step 1: Data given
2.0 M Al(NO3)3
Step 2:
Al(NO3)3 in water will dissociate as following:
Al(NO3)3 → Al^3+ + 3NO3^-
For 1 mol of Al(NO3)3 we will have 1 mol of Al^3+ and 3 moles of NO3^-
We know that the molarity of Al(NO3)3 = 2.0 M, this means 2.0 mol/ L
The mol ratio Al(NO3)3 and Al^3+ is 1:1 so the molarity of Al^3+ is<u> 2.0 M</u>
The mol ratio Al(NO3)3 and NO3^- is 1:3 so the molarity of NO3^- is<u> 6.0M</u>
The correct answer is: 2M Al3+(aq) and 6 M NO3-(aq)
The partial pressure of argon is:

This piece of porcelain is called a streak plate. This method is a method of rapid qualitative isolation and was developed by Robert Koch. It was developed to obtain pure bacterial cultures.
Answer: to see if the matter is a compound, mixture, or element.
Explanation:
can you please help with my most recent question :)
1. The forces make the train float because the poles are the same on each side causing them to repell (north and north repell)
2. B is more stable. If you pushed A it would fall and that would cause more disturbance
