Answer:
The gas is Methane at 340K
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:
Yes. These chemicals named barium chloride and calcium carbonate have been named properly. But silicon oxide has not been named correctly, an oxide of silicon is named as silicon dioxide not silicon oxide.
Explanation:
In chemistry while naming chemicals there are certain rules and naming the chemicals as per these rules is known as chemical nomenclature. The IUPAC's rule for chemical nomenclature of inorganic compounds can be read in a book named as red book.
<u>By sign convention, a cation is named first followed by an anion.</u> For example, in barium chloride (BaCl₂), barium which is represented by symbol Ba²⁺ is a cation and therefore written before chloride (Cl⁻) which is an anion. Similarly calcium carbonate is represented as CaCO₃.
As per the valency of silicon, it forms a dioxide with oxygen atom and it is represented as SiO₂.
Answer:
All rocks are constantly moving, but at a pace we cant see. Rocks might change from weather corrosion, or magma moving deep down. They are stable but sometimes can be unstable (earthquakes).
