An intensive property does not change when you take away
some of the sample. The procedures that a student could use to examine the
intensive property of a rectangular block of wood are the hardness, color,
density and molecular weight.
Explanation:
To solve this question, we need to use the following formula:
M = n/V
So:
M = ??
n = 2.634 mol
V = 25.2 L
M = 2.634/25.2
M = 0.105 mol/L
Answer: a. 0.105
Answer:-
+1
Explanation:-
Group 1 A compounds has 1 valence electron.
According to the octet rule, if outermost shell has 8 electrons then it is stable.
So Group 1 A compounds lose 1 electron to fulfill octet.
Oxidation number is the number of electrons lost or gained. It is positive if electrons are lost and negative if electrons are gained.
Hence the oxidation number of group 1 A compounds is +1.
