1. How do the different stages of development affect a person’s ability to react to situations? Explain briefly.
Answer:
A
Explanation:
Ductility, because it can be observed by altering the shape of the substance
The density of water is about 1.00 g/ml, so 500 ml of water is about 500 g
A 0.25m solution of NaCl is defined as a solution consisting of 0.25mol NaCl dissolved in 1kg water:
Which choice fits this definition: None does. I suggest that you recheck the data you have submitted - you have a mixture of moles, mass, etc and it is easy to make a mistake.
d) looks promising if it was: 1.0 mol NaCl dissolved in 4kg water.
I have overlooked C) as possible 0.25mol NaCl in 1kg water as being a little too obvious.
