a) Black
b) Non-magnetic
c) No reaction with carbon disulphide.
d) i don't know sry
But i had to go through my 6th grade notes for this .____.
Answer:
2 moles
Explanation:
number of mole =mass /molar mass
mass=36
molar mass=(2*1)+16=18
therefore, no of mole =36÷18 =2
Answer:
2KI → 2K + I₂
Explanation:
(not my definition, but form a trustworthy source)
The definition of a decomposition reaction is:
a chemical reaction in which one reactant breaks down into two or more products.
In this case, potassium iodide will decompose into potassium and iodine.
2KI → 2K + 2I
2 Potassium and 2 Iodine on both sides, so equation is balanced.
Or, it can be written as 2KI → 2K + I₂
Number of moles:
n = sample mass / molar mass
n = 15.00 / 74.6
n = 0.2010 moles of KCl
Therefore:
Molarity = moles / Volume
0.1107 = 0.2010 / V
V = 0.2010 / 0.1107
V = 1.815 L
