1. Determine if the ionic substances can break apart into ions.
- e.g. CaCO3 isn't very soluble, do it can't dissolve and dissociate. If it can't pop apart, no ions.
2. Swap the partners for all the other ions that you can get from step 1. You can skip pairings with the same charge - a + can't get close to another + to react.
3. Use solubility, acid/base, and redox rules to see if anything will happen with the ions in solution.<span />
8 tablets. To get 1 gram you would have to give 2 tablets every 6 hours. In 24 hours you would give 8 tablets (500 mg = .5 grams)
Explanation:
Binary acids are molecular compounds that consists of two components.
The components are Hydrogen and a non metal. Examples of binary acids include; HCl, HF etc.
The way to identify binary acids is to spot the hydrogen and the non metal.
You correctly said that you need the combined gas law.
combine gas law----> P1V1/T1= P2V2/T2
P1= ?
V1= 2.58 L
T1= 368K
P2= 777 torr
V2= 1.53 L
T2= 495K
Now we plug in the values.
(P1 X 2.58)/ 368= (777 X 1.53)/ 495 K
P1= 343 torr
