You can prove this by letting the water evaporate or using a instrument that can measure the solids in a liquid.
You have to go on a computer or phone and find how to draw a cube you did kind of good
Hello!
In chemistry, compounds can have one of two properties. Acidic and Basic.
To determine whether a compound/solution/test subject is basic or acidic, you need to look for the pH level. pH is a unit scale for your understanding.
1-6 on the pH scale means an item is acidic.
7 on the pH scale tends to be what we consider even ground as it matches the closest to the human bodies pH level.
Anything greater than 7 is considered basic.
Examples of basic solutions and compounds are many bleaches, milk of magnesia, ammonia, even limewater!
I hope this gives you an answer to your question.
The first choice is correct. K will give up electrons more easily, due to its smaller electronegativity.
