What current (in a) is required to plate out 2. 96 g of nickel from a solution of ni2 in 27. 12 minutes?

amid [387]

The current required to plate out 2.96 g of nickel from the solution of Ni²⁺ in 27.12 minutes is 5.95 A

<h3>Balanced equation </h3>

We'll begin by writing the balanced equation showing the number of faraday required to plate nickel. This is given below

Ni²⁺ + 2e —> Ni

Molar mass of Ni = 59 g/mol

Mass of Ni from the balanced equation = 1 × 59 = 59 g

Number of faraday = 2 F

1 faraday = 96500 C

2 faraday = 2 × 96500 = 193000 C

SUMMARY

From the balanced equation above,

59 g of Nickel was deposited by 193000 C of electricity

<h3>How to determine the quantity of electricity </h3>

From the balanced equation above,

59 g of Nickel was deposited by 193000 C of electricity

Therefore,

2.96 g of Nickel will be deposited by = (2.96 × 193000) / 59 = 9682.71 C of electricity

<h3>How to determine the current </h3>

Quantity of electricity (Q) = 9682.71 C
Time (t) = 27.12 mins = 27.12 × 60 = 1627.2 s
Current (I) =?

I = Q / t

I = 9682.71 / 1627.2

I = 5.95 A

Substances that make up a mixture __________ their own properties once they are combined to form a mixture. Please help. I need

Stels [109]

I believe the answer to this is;
Substances that make up a mixture RETAIN their own properties once they are combined to form a mixture.
I believe the answer is RETAIN because the combination in question is a MIXTURE. A mixture is a combination of various substances. In the case of mixtures, all the substances retain their own properties. That is; they remain the way they are and do not change. An example of a mixture is air. And to prove that air is a mixture;
The components of air retain their individual properties.
The components of air cannot be represented by a chemical formula
When the components of air combine, they do not show any form of chemical change, like heat release, change in pressure.....
Hope i helped, have a nice day.

in this lab we will build an instrument called a coffee cup calorimeter: identify the list with all the necessary parts

Nesterboy [21]

A calorimeter is just an insulated container which contains the sample. You combust the sample inside the calorimeter, then you measure the temperature with respect to time. Make sure to stir constantly. Thus, you need a thermometer and a stirrer. The coffee cup calorimeter is labelled as shown in the picture attached. The goal of this experiment is to determine the specific heat capacity.

In the Penny Lab that we ran, what is the independent variable? Question 1 options: the soap the number of water drops the penny

motikmotik

Answer:

I'd say it's the number of water drops.

Explanation:

The number of water drops is what you're controlling or purposely controlling and that answer choice makes the most sense out of the other answer choices. So I'd say it's "The Number of Water Drops."
