5 moles because molarity signifies number of moles dissolved in One litre of water
Pie4 years ago
7 0

Answer: Option (a) is the correct answer.

Explanation:

It is known that molarity is the number of moles of a substance present in liter of a solution.

Mathematically,    Molarity = \frac{\text{no. of moles}}{\text{volume in liter}}

Symbol which represents molarity is "M". For example, a solution of 5.0 M means that molarity of the solution is 5.0 or the solution is 5.0 molar.

Thus, we can conclude that a solution that is labeled 5.0 M would be read as 5.0 molar.

Laser fusion Group of answer choices uses chemical reactions to produce energy uses nuclear reactions to produce energy implodes
KonstantinChe [14]

Answer:

Uses nuclear reactions to produce energy

Implodes a fuel pellet

Explanation:

Laser fusion is a method of initiating nuclear fusion reactions through heating, and compressing fuel pellets containing deuterium and tritium using high energy density laser beams. Lase fusion is also known as inertial confinement fusion and the energy produced by the process is known as Laser Inertial Fusion Energy, LIFE.

During the process of laser fusion, small pellets of deuterium-tritium (DT) isotopes mixture are fed into a blast chamber where they are compressed to high densities using a number of amplified laser beams in the chamber.

The high energy density of the beams as well as the heat produced due to compression, induces the thermonuclear explosion ignition resulting in the production of high energetic products such as charged particles, x-rays and neutrons. The energy produced is absorbed and stored as heat in a blanket that is then used in a steam thermal cycle to generate electrical power.

There are two methods of compression of the DT pellet: direct and indirect-drive laser fusions.

However, there are a number of limitations to energy production by this process. One limitation is that the process is extremely inefficient in energy energy production. Also, the heat produced by the flashtubes results innthe deformation of the laser glass.

Which is the balanced version of the half-reaction below?<br> H2S → S+H+
chubhunter [2.5K]

Answer:

C. H_2S\rightarrow S+2H^++2e^-

Explanation:

Hello there!

In this case, according to the given chemical reaction, it turns out possible to realize there is one sulfur atom on each side of the chemical equation but two hydrogen atoms on the left and one on the right, which means the latter must be balanced in agreement to the law of conservation of mass.

In such a way, by setting a 2 on H⁺, the reaction will be balanced:

H_2S\rightarrow S+2H^+

Now, we count the transfer electrons for sulfur from -2 to 0 as 2e⁻ on the right, which will match with the option C.

H_2S\rightarrow S+2H^++2e^-

Regards!
