Answer: Time required to deposit an even layer of gold with given thickness is
sec.
Explanation:
The given data is as follows.
Surface area = 49.8
,
Density of gold = 19.3
,
Current = 3.15 A, thickness of gold layer = 
It is known that relation between volume, area and thickness is as follows.
V = Surface area × Thickness
= 
= 0.05988 
Therefore, we will calculate the time required to deposit an even layer of gold with given thickness is calculated as follows.

=
sec
Thus, we can conclude that time required to deposit an even layer of gold with given thickness is
sec.
Answer:
False
Explanation:
2CH₄ + 2O₂ ⟶ 2CO₂ + 2H₂O
Let’s count the atoms on each side of the reaction arrow.
<u>Atom</u> <u>On the left</u> <u>On the right</u>
C 2 2
H 8 4
O 4 6
C is balanced, but there are different numbers of H and O on each side.
The equation is not balanced
