1,1,2 & single replacement reaction
Answer:
The water will eventually become the same temature (A)
The correct answer would be D: Physical properties can be observed without changing the identity of a substance
I believe the correct response is A. At higher elevations it would take less time to hard boil an egg, because there is less atmospheric pressure.
Volume ⇒ 50 mL in liters : 50 / 1000 = 0.05 L
Molarity of solution ⇒ 0.15 M
Number of moles:
n = M * V
n = 0.15 * 0.05
n = 0.0075 moles of CuCl2
hope this helps!.
