First, we'll identify the beaker containing pure water as follows:
We'll take equal masses from each of the three beakers and measure the mass of each.
We'll then identify the density of each by using the rule : density =mass/volume
Pure water will be the liquid having density equal to 1 gm/cm^3
Then, we'll differentiate between the salt and sugar solution by measuring the conductivity of each solution. Salt solution is a good conductor while solution of sugar is a bad conductor.
Fe2O is the formula for that
Ummmm if YOU were asked this question then only YOU can answer it not us cuz we don’t know what ur resting heart rate is..... but if ur asking what ours is mine is 104 bpm
Lol
Answer: b, and e
Explanation:
b) n = 3 , l = 2 , m = 1 , m s = − 1/2
e) n = 5 ,l= 4 , m = − 4 , m s = − 1/2
