CO2 will be the first to boil because it will be the first to warm up because it is the closest temperature to 0
Im pretty sure its A funding because thats alot of money
AgNO3+NaCl yields AgCl+NaNo3 (reduction)
...that's the only one I know
Answer:
Grey precipitate implies the presence of silver ions
Yellow precipitate implies the presence of lead II ions
Explanation:
Qualitative analysis provides us a quick method of identifying ions present in a sample by chemical reactions involving simple reagents. Precipitates having a unique colour is formed. The identity of ions in the sample is deduced from the colour of precipitate obtained when particular reagents are added.
In the question, a precipitate containing silver ions upon standing turn into grey colour. Similarly, lead II ions give a yellow precipitate.
I'm happy to help but do you have the options?
