Answer:

Batteries operate by allowing charged ions to pass through an electrolyte solution.

A battery is essentially a device made up of one or more electrochemical cells capable of transforming stored chemical energy into an electric current. Each cell is comprised of a positive electrode (anode), a negative electrode (cathode), and electrolytes facilitating ion movement between the electrodes, enabling the current to flow from the battery to perform its function.

Explanation:

Its functionality is fundamentally reliant on a reversible chemical reaction known as reduction-oxidation, where one component undergoes oxidation while another is reduced; this process does not consume or lose any components but merely alters their oxidation states, allowing them to revert to their initial states under suitable conditions.

Why the gross reading is needed when doing the titration?

Anarel [852]

Answer:

The response is provided below.

Explanation:

Numerous aspects can influence the actual results of titration. These factors vary from human error to misjudging measurements, a researcher's interpretation of color changes, and improper techniques during the experimental procedure.

Thus, to mitigate these errors, researchers must engage thoroughly throughout experimentation, and employing gross readings can assist in reducing mistakes when determining the final titre value.

An experimental drug, D, is known to decompose in the blood stream. Tripling the concentration of the drug increases the decompo

lions [985]

Answer:

The rate law for the decomposition reaction is:

$R=k[D]^2$

The unit for the rate constant will be $M^{-1}s^{-1}$

Explanation:

$D\rightarrow Product$

The rate law can be expressed as:

$R=k[D]^x$ ..[1]

When the drug concentration is tripled, the decomposition rate rises by a factor of nine.

$[D]'=3[D]$

$R'=9\times R$

$R'=k[D]'^x$ ...[2]

[1] ÷ [2]

$\frac{R}{R'}=\frac{k[D]^x}{k[D']^x}$

$\frac{R}{9R}=\frac{k[D]^x}{k[3D]^x}$

$9=3^x$

Solving for x results in:

x = 2.

This indicates a second-order reaction.

The decomposition reaction's rate law is:

$R=k[D]^2$

The unit for the rate constant will be:

$k=\frac{R}{[D]^2}=\frac{M/s}{(M)^2}=M^{-1}s^{-1}$

The unit for the rate constant will be $M^{-1}s^{-1}$ .

Next we need to determine the mass of oleic acid in the monolayer. The concentration of the oleic acid/benzene solution is 0.02g

Alekssandra [968]

Response:

$m=1x10^{-6}g$

Clarification:

Hello,

In this scenario, since a single drop equates to 0.05 mL of the solution provided, with a concentration of 0.02 g/mL, the mass of oleic acid in one drop calculates to:

$m=0.02\frac{g}{L}*0.05mL*\frac{1L}{1000mL}\\ \\m=1x10^{-6}g$

Best wishes.

A hardware salesman measures the mass of a box containing

lorasvet [956]

Step $1$ : To find the mass of a single washer, divide the total measured mass by the number of washers $\frac{0.4168}{1000} =0.0004168\ Kg$ $0.0004168kg=4.168*10^{-4} kg$ . Step $2$ : Convert kilograms to milligrams knowing $1 kg=1*10^{6} mg$ ; thus $4.168*10^{-4}*10^{6} =4.168*10^{2}mg=416.8 mg$ resulting in the final answer $416.8 mg$ .
