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.

What is the molar solubility of MgF2 in a 0.36 M Mg(NO3)2 solution? For MgF2, Ksp = 8.4 × 10^–8
Answer:
2.4 × 10⁻⁴ M
Explanation:
Step 1: Calculate the concentration of Mg²⁺ coming from Mg(NO₃)₂
Mg(NO₃)₂ is a strong electrolyte and the molar ratio of Mg(NO₃)₂ to Mg²⁺ is 1:1. The initial molar concentration of Mg²⁺ is 1/1 × 0.36 M = 0.36 M.
Step 2: Make an ICE chart for the solution of MgF₂
MgF₂(s) ⇄ Mg²⁺(aq) + 2 F⁻(aq)
I 0.36 0
C +S +2S
E 0.36+S 2S
The solubility product constant is:
Ksp = [Mg²⁺] × [F⁻]² = (0.36+S) × (2S)²
Since S <<< 0.36, 0.36+S ≈ 0.36.
Ksp = 0.36 × 4S² = 8.4 × 10⁻⁸
S = 2.4 × 10⁻⁴ M

Explanation:
matter i am pretty sure
The law that allows calories to be determined by heat (energy) transfer from one substance to another, but it is never destroyed is first law of thermodynamics.
What is first law of thermodynamics?Energy cannot be generated or destroyed, only changed in form, according to the basic law of thermodynamics.
Energy transfer occurs when mass crosses the control boundary, external work is performed, or heat is transferred across the boundary in any system. These cause the stored energy in the control volume to shift.Hence first law of thermodynamics justify the given statement.

Answer:
Final pressure = 6 atm
Final volume = 1.1 L
Final temperature = 100 K
Explanation:
We are given;
Initial Pressure; P1 = 2 atm
Initial volume; V1 = 3.3 L
Initial temperature; T1 = 27° C + 273 = 300 K
Final pressure; P2 = 6 atm
We will use Boyles law to get the final volume.
P1V1 = P2V2
V2 = (P1 × V1)/P2
P2 = (2 × 3.3)/6
V2 = 1.1 L
We can use Charles law to find the final temperature.
V1/T1 = V2/T2
T2 = (V2 × T1)/V1
T2 = (1.1 × 300)/3.3
T2 = 100 K

Liquid methylene bromide has a density of 2.50 g/mL. A barometer is constructed using methylene bromide instead of mercury. If the atmospheric pressure is 0.950 atm, what is the height of the methylene bromide column in the barometer in cm
Answer:
393 cm
Explanation:
Step 1: Given and required data
Density of liquid methylene bromide (ρ): 2.50 g/mL (2.50 g/cm³)Earth's gravity (g): 9.81 m/s²Atmospheric pressure (P): 0.950 atmStep 2: Convert 0.950 atm to Pa (N/m²)
We will use the conversion factor 1 atm = 101325 Pa.
0.950 atm × 101325 Pa/1 atm = 9.63 × 10⁴ Pa
Step 3: Convert 2.50 g/cm³ to kg/m³
We will use the conversion factors:
1 kg = 10³ g1 m³ = 10⁶ cm³[tex]\frac{2.50g}{cm^{3} } \times \frac{1kg}{10^{3}g } \times \frac{10^{6}cm^{3} }{1m^{3} } = 2.50 \times 10^{3} kg/m^{3}[/tex]
Step 4: Calculate the height (h) of the liquid column
We will use the following expression.
P = ρ × g × h
h = P / ρ × g
h = 9.63 × 10⁴ Pa / (2.50 × 10³ kg/m³) × 9.81 m/s²
h = 3.93 m = 393 cm

the beaker contains 0.2556 m h2so3 and the buret contains 0.3106 m naoh what happens to the conductivity during titration
Answer:
Before the equivalence point, conductivity is decreasing. After the equivalence point, conductivity is increasing
Explanation:
In solution H2SO3 produce H+ ions and SO3²⁻ ions. In the same way, NaOH produce Na⁺ and OH⁻ ions. The conductivity of a solution is directly proportional to the concentration of ions in a solution. During titration, you are adding more NaOH (That is, more Na⁺ and OH⁻ ions). But each moles of OH⁻ reacts with H⁺ ion producing H₂O. That means the moles of Na⁺ that you are adding = Moles of H⁺ are been consumed. The concentration of ions remains approximately constant. But, H⁺ ion conducts better than Na⁺ ion. That means before the equivalence point, conductivity is decreasing. But after the equivalence point you will add OH- ions in excess increasing ion concentration increasing the conductivity:
After equivalence point, conductivity is increasing.

Answer:
Explanation:
Just saw your request regarding answering this so here it is:
All of them belong of Group 1 in periodic table and thus are highly reactive! Pattern of reactivity for Group 1 (Alkali metals) increases as you move down the group as their radius keeps increasing and thus electrons can be easily lost. Thus, to ID the lumps, Sheena should look at their reactivity and she should get the following trend:
Most reactive: Potassium (K)
Intermediate: Sodium (Na)
Least reactive: Lithium (Li)
