false I think, but not so sure
A) acids because they start with h
Answer:
C. 7.50g
Explanation:
The percent (%) by mass of a solute in a solution refers to the number of grams contained in 100g of solution by that solute. In this case, 5% by mass of pottasium chloride (KCl) means 5g of KCl is contained in 100g of solution.
Therefore, in 150g of solution, there would be:
5g/100g × 150g
= 0.05 × 150
= 7.50g of KCl solute.
Hence, 7.50g of pottasium chloride would be expected to be collected by evaporating 150.0 g of the solution.
Carbon? i am confused, if you're asking for the element or what is happening, i need a bit of clarification!
Any atom can be considered stable if it has an equal number of protons and electrons, giving it a net charge of zero.
