Answer:
In the presence of salt water and oxygen the coating will not corrode. As long as zinc coating is present and remains intact corrosion is not possible.
Explanation:
Here it is given that a tin is present so firstly tin is made of a chemical element
which belongs to carbon family in periodic table of group 14.
It is a silvery,soft, white metal with a bluish tinge.
Now the covering which is been done on the tin is Zinc.
so, zinc is known to be served as a sacrificial coater.
Their is an amazing reason behind zinc coating being so effective and intact i.e. Its own corrosive properties are such that it stops corrosion.
Their is a process which is known as a galvanic corrosion which refers to that "ZINC" defers to the metal to which it is protecting.
It is even more electrochemically active than iron itself.
Here, it is mentioned that zinc coating gets chipped but the coating remains intact. So, if the zinc is not removed from the tin's surface it will not get corroded when it is exposed to salt water and oxygen.
Answer:
It will cost $68,620.5 to the club to add the grass turf to their field.
Explanation:
length of the field = l = 0.102 km = 0.102 × 1000 m
( 1km = 1000 m)
Width of the field w = 0.069 km = 0.069 × 1000 m
Area of the field , A= l × w
Cost of grass turfing = 
Cost of grass turfing on field of 
:

No. Magnesium, and Bromine are a chemical compound when put together.
Neither Bromine, nor Magnesium react with any sort of water.
Answer:
4 moles of neon
Explanation:
Given data:
Number of moles of neon = ?
Number of atoms of neon = 2.4×10²⁴ atoms
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
For given neon atoms:
1 mol = 6.022 × 10²³ atoms
2.4×10²⁴ atoms × 1 mol / 6.022 × 10²³ atoms
0.4×10¹ mol = 4 mol
