The numbers in the powers are the number of electrons in a specific orbital. so you can add them to find the atomic number
Answer:
The answer is: 18 moles and 1341, 72 grams of KCl
Explanation:
The molarity is defined as the moles of solute ( in this case KCl) in 1 liter of solution:
1L solution-----3 moles of KCl
6L solution-----x= (6L solutionx 3 moles of KCl)/1 L solution= <em>18 moles of KCl</em>
<em></em>
We calculate the weight of 1 mol of KCl:
Weight 1 mol KCl= Weight K + Weight Cl= 39,09 g + 35, 45 g=74, 54 g/mol
1 mol KCl----- 74, 54 g
18 mol KCl----x= (18 mol KCl x 74, 54 g)/1 mol KCl=<em>1341, 72 g</em>
Physical changes are changes that change the physical traits of the substance, without making any change in their internal structure. Chemical changes effect internal structure of the substance and new substance is formed.
Examples of physical changes - breaking glass, evaporating alcohol, shredding paper...
Chemical : burning paper, heating sugar to form caramel, rusting of iron...
