Which of the following best describes the process of electroplating?
sweet-ann [11.9K]
I think the correct answer would be B. The process of electroplating uses a direct current in order to give a cheap metal the apperance and resistance of a more expensive metal by coating it with a certain metal. The current reduces the dissolved metal ions to form a thin coating on a surface.

Naturally occurring copper exists in two isotopic forms: 63Cu and 65Cu. The atomic mass of copper is 63.55 amu. What is the appr
Mariulka [41]
To calculate the average atomic weight, each exact atomic weight is multiplied by its percent abundance, then, add the results together.  If the natural abundance of 63Cu is assigned x, the natural abundance of 65Cu is 1-x (the two abundance always add up to 1). So the solution is: (63)(x)+(65)(1-x) = 63.55, 63x+65-65x=63.55, x=0.725=72.5%. The natural abundance of 63Cu is 72.5%, that of 65Cu is 1-72.5%=27.5%.

What is a limitation of using a chemical formula, such as CGH1206, to represent a compound?
Tpy6a [65]

Answer:

The chemical formula does not show how the atoms are connected to one another.

Explanation:

With a chemical formula, you can see the types of elements that make up the compound, the number of atoms of each element in a molecule, and the chemical symbols of the elements in the compound.

What is the resultant pressure if 1.7 mol of ideal gas at 273 K and 2.79 atm in a closed container of constant volume is heated
dedylja [7]

Answer: The resultant pressure is 3.22 atm

Explanation:

Gay-Lussac's Law: This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles.

P\propto T     (At constant volume and number of moles)

\frac{P_1}{T_1}=\frac{P_2}{T_2}

where,

P_1 = initial pressure of gas  = 2.79 atm

P_2 = final pressure of gas  = ?

T_1 = initial temperature of gas  = 273K

T_2 = final temperature of gas = 315 K

\frac{2.79}{273}=\frac{P_2}{315}

P_2=3.22atm

Thus the resultant pressure is 3.22 atm
