The correct answer is D. Using the law of conservation of mass the number of atoms on each side of the equation should be equal. Through introspection, we find that there are 2 atoms on reactant side as opposed 3Cl atoms on product side. If we add a coefficient of 3 on we get
.
Now there are 6Cl atoms on reactant side and 2 on product side, hence we add a coefficient of 2 on both and . The balanced chemical equation is,
<u>Answer:</u> The cell notation for the given cell will be:
<u>Explanation:</u>
The half cell reaction follows:
<u>Oxidation half reaction:</u>
<u>Reduction half reaction:</u> ( × 2)
<u>Net reaction:</u>
Oxidation reaction always occurs at anode.
Cell notation is the representation in which, the anode is written on left hand side followed by its ion with its molar concentration. It is then followed by a salt bridge, which is represented by the symbol "||" . Then the cathodic ion with its molar concentration is written and then the cathode.
Hence, the cell notation for the given cell will be:
I believe it measures the pressure in the atmosphere. Not positive on the name...barometric pressure gauge?
Answer:
C4H8O4
Explanation:
Let (CH20)x
C=1*12.01=12.01 (12.01, 1.01, 16.00 Avg mass of elements)
H=2*1.01=2.01
O=1*16.00=16.00
12.01 + 2.01 + 16.00 = 30.03
120.12/30,03=4
==> (CH2O)4 = C4H8O4
Answer:
See below.
Explanation:
The period is not the same regardless of the string length.
The longer the length the greater is the period ( the period varies directly with the square root of the length).
The equation of the relationship is T = 2π√(l/g) where l = the length of the string and g is the acceleration due to gravity.
