Answer:

D.) Research on animals in which the animal experiences no fear or pain.

Explanation:

It is ethical to perform test on an animal such that the animal experiences no fear or pain.  

It is unethical to perform test on an animal when some other tests can be performed without the animal to get the desired results.  

Polluting the water resource with contamination is an unethical practice.  

People who are vulnerable cannot be subjected to experiments.

The answer is D because it sounds like the most ethical answer. The other choices are wrong because the could possibly hurt someone or an animal.

In large generators in power plants, ___________ rotate inside a coil of wire to produce an electric current
lapo4ka [179]
<h3><u>Answer;</u></h3>

Magnets

In large generators in power plants, <u>magnets</u> rotate inside a coil of wire to produce an electric current.

<h3><u>Explanation;</u></h3>
  • Generators are devices that use electromagnetic induction to convert mechanical energy to electrical energy.
  • In power plants, large wheel known as turbine that rotates when pushed by steam,wind, or water and provides mechanical energy to a generator.
  • <u><em>Generators are used in power plants and have very large quantities of copper wire spinning around inside very large magnets, at very high speeds. A turbine spins the shaft that runs the generator. Eventually, electric current is generated.</em></u>

Rank the following in terms of decreasing miscibility in C₈H₁₈ (octane), a major component of gasoline:
Aleksandr-060686 [28]

Answer:

In order of decreasing miscibility

C₉H₂₀ (nonane)→C₂H₅F (fluoroethane)→C₂H₅Cl (chloroethane)→H₂O (water)

Explanation:

The solubility of a solid is a measure of its ability to dissolve in a liquid while for liquids,  the miscibility is a measure of thhe liquid to mix with anoyjer liquid resulting in a soltion which can hold any amount of either liquids. Immiscible liquids are those that are not soluble or have very limited solibility with each other.

C₉H₂₀ (nonane)→C₂H₅F (fluoroethane)→C₂H₅Cl (chloroethane)→H₂O (water)

In the order of decreasing miscibility as like dissolve like, ability to dissociate and polar and organic characteristics are considered

An alloy of bronze is manufactured by melting 51.2 g of copper with 6.84 g of tin. What is the percent copper in the bronze?
Harlamova29_29 [7]

Answer:

Percentage of copper = 88%

Explanation:

Given data:

Mass of copper = 51.2 g

Mass of tin = 6.84 g

Percentage of copper = ?

Solution:

Formula:

Percentage of copper = mass of copper / total mass × 100

Now we will determine the total mass:

Total mass = mass of copper + mass of  tin

Total mass = 51.2 g + 6.84 g

Total mass = 58.04 g

Now we will calculate the percentage of copper.

Percentage of copper = 51.2 g / 58.04 g × 100

Percentage of copper = 0.88 × 100

Percentage of copper = 88%
