Answer:

20%

Explanation:

The fish consumption has had lot of variations in the past few centuries, most noticeably in the last century. Initially it was the richer countries that had population which was consuming the most animal protein from fish in the world, while the developing nations had less. Things have changed though, especially during the 1990's, when the developing nations experienced a rapid increase in the consumption of fish. This was largely due to the growing standard and the availability of fish, so in some of the developing nations the percentage of animal protein from fish reached around 20%.

Write the half-reactions as they occur at each electrode and the net cell reaction for this electrochemical cell containing tin

mojhsa [17]

The half reactions as they occur at each electrode

is as follows

at the anode Sn(s) =sn^2+(aq) + 2e -
at the cathode 2 ag^+(aq) + 2e - = 2Ag (s)

net cell reaction = Sn (s) + 2Ag^+(aq) = sn^2+ (aq) + 2 Ag (s)

Scrat [10]

Which two solutions, when mixed together, will undergo a double replacement reaction and form a white, solid substance?

1. NaCl(aq) and LiNO3(aq)

2. KCl(aq) and AgNO3(aq) answer

3. KCl(aq) and LiCL(aq)

4. NaNO3(aq) and AgNO3(aq)

2 is the answer because AgCl is formed and that is a white ppt.

In the experiment "Beer-Lambert’s Law and Spectrophotometry", you prepared a calibration plot similar to the one pictured below.

dexar [7]

Answer:

0.025M

Explanation:

As you must see in your graph, each concentration of the experiment has an absorbance. Following the Beer-Lambert's law that states "The absorbance of a solution is directely proportional to its concentration".

At 0.35 of absorbance, the plot has a concentration of:

Modeling Nuclear Processes Quick Check

Valentin [98]

The phrase which best describes nuclear fusion is: A. the process by which small nuclei combine into a larger nucleus.

A nuclear reaction can be defined as a type of chemical reaction in which the nucleus of an atom of a radioactive chemical element is transformed by either being joined (fusion) or split (fission) with the nucleus of another atom of a radioactive chemical element and accompanied by a release of energy.

Generally, there are two (2) main types of nuclear reaction and these include:

<u>Nuclear fission:</u> it involves the collision of a heavy atomic nucleus with a neutron, thereby causing a split and release of energy.

<u>Nuclear fusion:</u> it involves the joining of two smaller nuclei of atoms to form a single massive or heavier (larger) nucleus with the release of energy.

In conclusion, nuclear fusion is best described as the process by which small nuclei combine into a larger nucleus, accompanied by a release of energy.
