Answer:
24 hours
Explanation:
The computation is shown below:
The needed mole of
is
= 5 ÷22.4 = n
Also 1 mole of
required four electric charge
Now the charge needed is
= n × 4 × 96,500 C
= 4 × 96,500 × 5 c ÷ 22.4
= 86160.714 C
Now
q = i t
t = q ÷ i
= 86160.714 C ÷ 0.995
= 86593.7 seconds
= 24 hours
Hence, the correct option is A.
A sedimentary rock is a rock formed from water. An igneous rock is a rock that is formed by magma ( lava from a volcano ). A metamorphic rock is a rock formed by heat or pressure.
Oxygen is the only element in that list, the rest are compounds.
The answer is the first: that structural models provide minimal three-dimensional information. This is because the ball-and-stick model cannot show the actual size of the atoms depicted in the model. You also cannot see the actual bond lengths between the atoms. This, then, limits the accuracy of the model and fails to precisely portray how the chemical compounds being shown are like in all actuality. Thus, though you do see a three-dimensional picture of the chemical compound, this picture is not completely accurate and is not scaled to size.
