what is electroplating? write complete process of electro plating with the example​

Answers

Answer 1

Answer:

Electroplating is the process of applying a metal coating on another piece of metal (or another conductive surface) through an electro-deposition process. In electroplating, the deposited metal becomes part of the existing product with the plating/coating.

Explanation:

To understand the concept further, let’s take an example of a gold coating. In this instance, a layer of gold is to be electrodeposited on metallic jewellery to enhance its appearance.Usually, the gold plating is connected to the anode (+ve charged electrode) of the circuit and the jewellery is kept at the cathode (-ve charged electrode). Both are kept immersed in a highly developed electrolytic bat (solution). At this stage, a DC current is supplied to the anode that oxidizes the gold atoms and dissolves them into the solution.The dissolved ions of gold are reduced at the cathode and plated on the jewellery.However, there are major factors that influence the last plating. These include:The voltage level of current.The temperature and chemical composition of the bath.The current length of time.The distance between the cathode and the anode.

Where does much of our history of Precambrian rocks come from? fossils on the rock surface ores mined from shields ash taken from volcanoes trenches on the sea floor

Answers

Answer:

Ores mined from shields.

Explanation:

Ores mined from shields are the source from which we get the history of Precambrian rocks. The Ores from shield experience the Precambrian era so that's why its rocks provides information about that era. The Precambrian supereon is the division of the geological time scale which is the first and longest stage in the history of the Earth which also includes the Hádic, Archaic and Proterozoic eons.

To determine the molar mass of an element, one must know the element's
a. number of isotopes.
b average atomic mass
c avogradro constant
d atomic number​

Answers

Answer:

d

Explanation:

from you know the atomic number it should be easy to find

To determine the molar mass of an element, one must know the element's atomic number​. Therefore, option D is correct.

What is the atomic number ?

An element's atomic number (Z) is the number of protons in the nucleus of each atom of that element. This means that the number of protons is the feature that distinguishes each element from all others. Elements differ based on their atomic number.

Because the combined masses of protons and neutrons account for nearly all the mass of a given atom, the atomic mass of a single atom can be calculated by adding the total number of protons and neutrons of that particular isotope.

The atomic mass of any element on the periodic table can be used to calculate its molar mass.

Thus, option D is correct.

Provide one example where a neutralization reaction is undesired/harmful. State the reactants and explain why it is harmful for this reaction to take place.

Answers

Answer:

You're in my science class wth

Explanation:

For instance farmers are using basic fertilizers to neutralize an acid soil –which is harmful for the plants- while basic solutions are added in the chimneys of factories to neutralize the acid smoke that they produce –avoiding the catastrophic effects of the acid rains. Acid released in the environment from industry creates acid rain which has many ecological effects. Acid rain makes waters acidic, and causes them to absorb the aluminium that makes its way from soil into lakes and streams. This combination makes waters toxic to crayfish, clams, fish, and other aquatic animals.

Answer:

D, The volume will be multiplied by a factor of 4

Explanation:

First find the height

V = π(r^2)h

Plug in what we know

83 = π(3^2)h

83 = π(9)h

83  = (9π)h

9[tex]\pi[/tex] = 28.27

83/28.27 = (28.27)h/28.27

h = 2.94

Then find the volume of the new can by doubling the radius

3 x 2 = 6

r = 6

V = π(r^2)h

V = π(6^2)2.94

V = π(105.84)

V =332.51

For the first one, they rounded to the nearest whole #, so let's do the same.

V = 333

Then divide 333 by 83 to get 4

Therefore, the volume will be multiplied by a factor of 4

What is the new concentration of a solution of CaSO3 if 10.0 mL of a 2.0 M CaSO3 solution is diluted to 100 ml?

Answers

Answer: The new concentration of a solution of [tex]CaSO_{3}[/tex] is 0.2 M 10.0 mL of a 2.0 M [tex]CaSO_{3}[/tex] solution is diluted to 100 mL.

Explanation:

Given: [tex]V_{1}[/tex] = 10.0 mL,      [tex]M_{1}[/tex] = 2.0 M

[tex]V_{2}[/tex] = 100 mL,           [tex]M_{2}[/tex] = ?

Formula used to calculate the new concentration is as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]

Substitute the values into above formula as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}\\10.0 mL \times 2.0 M = M_{2} \times 100 mL\\M_{2} = 0.2 M[/tex]

Thus, we can conclude that the new concentration of a solution of [tex]CaSO_{3}[/tex] is 0.2 M 10.0 mL of a 2.0 M [tex]CaSO_{3}[/tex] solution is diluted to 100 mL.
