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.

Susan conducts an experiment five times and gets a solution concentration of 1.9M, 2.1M, 1.8M, 1.9M, and 2.2M. The known concent

Answer:

This question is incomplete; the complete part/options is:

A) They are precise, but not accurate.

B) They are accurate, but not precise.

C) They are both accurate and precise.

D) They are neither accurate nor precise

The answer is C.

Explanation:

Accuracy refers to how close a series of measurements is to a known or true value while precision is the closeness of the measurements to one another.

The known concentration of a solution is 2.0M. In an experiment which Susan conducts five times and gets a solution concentration of 1.9M, 2.1M, 1.8M, 1.9M, and 2.2M respectively.

Based on these measured solute concentrations, one would observe that the measured values of: 1.9M, 2.1M, 1.8M, 1.9M, 2.2M are close to one another. This means that the measurements are PRECISE.

Also, the measured values are not too distant from the known value of 2.0M, hence, it can be said that the measurements are ACCURATE.

Therefore, Susan's measurements of the solute concentration are both accurate and precise.

A flask contains 0.160 mol of liquid bromine, what are the number of bromine molecules present

slega [8]

Answer:

9.64 x 10^22

Explanation:

To go from moles to molecules, you multiply by Avogadro's number, 6.022 x 10^23, so you get 9.64 x 10^22.
