Answer:
ΔS < 0
ΔH < 0
Explanation:
Recall that the process is crystallization. Crystallization involves conversion of aqueous ions back to solid. This process decreases the entropy of the system hence ΔS is negative.
But remember that a process is only spontaneous when ΔG <0 (negative). From;
ΔG = ΔH - TΔS
If ΔS is negative, then (-TΔS) must be positive since ΔS is negative. The only way to make the process spontaneous is to make ΔH negative so that ΔG also becomes negative.
Orbital s is always the first one to fill up
That's a compound
The Cu stands for Copper, and the O stands for oxygen
Answer:
Explanation:
A scientific investigation typically begins with observations. Observations often lead to questions. A hypothesis is a possible logical answer to a scientific question, based on scientific knowledge. A prediction is a statement that tells what will happen under certain conditions
Answer: A. 1,1,1
Explanation:
The coefficients that will balance the equation; NH4OH(aq) →H2O(l) + NH3(g), is 1, 1, 1, because it proves the total number of atoms of each element on the LHS and RHS of the equation are equal, hence balanced.
LHS RHS
N = 1 1
H = 5 5
O = 1 1
