B Chromium used on bath taps to get shiny appearance
C Copper used for making electrical wires
D To protect iron objects used in machineries, from corrosion
If you answer you will get brainiest
Please answer and thank
Answers
Answer:
C. Copper used for making electrical wires
Explanation:
When a coating of a particular metal is applied on another metal, the process is termed as electroplating. The process is carried by the process of electro-deposition. This process is carried on in order to enhance the quality of the objects manufactured. The coating helps in resistance and provides an attractive appearance to the object.
Option C. is not an example of electrocoating because on the copper wires no other metal coating is done. In all the other three options, coating has been done on the object.

_ Na+Cl 2 -> _NaCl
reactant side number of atoms?
Na = ?
Cl = ?
Product side number of atoms?
Na = ?
Cl = ?
what is the final equation?
_ Na+Cl 2 -> _NaCl
Answers
Answer:
2Na+Cl2 -> 2NaCl
Explanation:
1Na+1Cl 2 -> 1NaCl (i'm assuming they want you to balance it so ill start with 1)
Na = 1
Cl = 2 (it is 2 because it is Cl2, meaning that there are 2; but remember that you cannot change this number only coefficients)
Na = 1
Cl = 1
We need to have 2 Cl on the product side
1Na+1Cl 2 -> 2NaCl
Now we need 2 Na on the reactants side
The final equation is
2Na+Cl2 -> 2NaCl
Now it is balanced
Na = 2
Cl = 2
--
Na = 2
Cl = 2

Answers
Answer:
[tex]2Al(s) + 3NiSO4 --> Al2(SO4)3 + 3Ni[/tex]
Explanation:
This reaction type is a single replacement. The format of a single replacement is:
[tex]A+BC --> B+AC[/tex]
A= Al
B= Ni
C= SO
The coefficient 3 for Ni would become a subscript for AC. After you plug those into the reaction you need to count how many of each are on the left side and try to get the same number on the right side. Both sides must be equal to have a balanced equation.

Describe how greater distance affects the appearance of an object’s size and brightness
Answers
Answer:
Distance also affects the apparent brightness of an object. A distant, but very energetic star can appear dimmer to us than a lower-energy, but closer one. ... Each of their effective temperatures results in a different brightness for the object. The quasar, however, is very far away, and so appears dim.
