A radiometer spins when what type of heat energy is taking place originally come from?

Justify the statement, "nuclear energy is harmful as well as useful."

Olenka [21]

Nuclear energy is harmful because it releases of harmful ionizing radiation and has been employed in the production of atomic bombs and hydrogen bombs.

Nuclear energy is beneficial in that it produces vast amount of energy for domestic and industrial purposes.

<h3>What is nuclear energy?</h3>

Nuclear energy refers to the energy which is produced as a result of the changes that occur in the nucleus of atoms of elements.

Nuclear energy produces the largest amount of energy when compared to other forms of energy sources.

Nuclear energy is produced by two types of nuclear reactions:

Nuclear fission and Nuclear fusion

Nuclear energy is harmful in that it results in the release of harmful ionizing radiation which damages cells and tissues of living organisms.

Nuclear energy is also harmful because nuclear energy has been employed in the production of atomic bombs and hydrogen bombs.

On the other hand, nuclear energy is beneficial in that it produces vast amount of energy which can be used for domestic and industrial purposes. It also produces fewer wastes that damage the environment compared to fossil fuels.

In conclusion, nuclear energy is both beneficial and harmful.

Calculate the wavelength of the first line in the lymen series of hydrogen spectrum

Natali [406]

Since the electron is de-exited from 1(st) exited state (i.e n=2) to ground state (i.e n=1) for first line of Lyman series. Since the atomic number of Hydrogen is 1. λ = 4/3⋅912 A. 1/R = 912 A

An analytical chemist is titrating 242.5 mL of a 1.200 M solution of hydrazoic acid HN3 with a 0.3400 M solution of NaOH. The pK

rodikova [14]

Answer:

The pH of the solution is 12.61

Explanation:

Step 1: Data given

Molarity of hydrazoic acid solution = 1.200 M

Volume of solution = 242.5 mL

Molarity of NaOH solution = 0.3400 M

pKa = 4.72

Step 2: The balanced equation

HN3 + NaOH → NaN3 + H2O

Step 3: Calculate moles hydrazoic acid

Moles hydrazoic acid = molarity * volume

Moles hydra

zoic acid = 1.200 M * 0.2425 L

Moles hydrazoic acid = 0.291 moles

Step 4: Calculate moles NaOH

Moles NaOH = 0.3400 M * 1.006 L

Moles NaOH = 0.342 moles

Step 5: Calculate the limiting reactant

HN3 is the limiting reactant. It will completely be consumed (0.291 moles)

NaOH is in excess. There reacts 0.29 moles. There will remain 0.342 - 0.291 = 0.051 moles NaOH

Step 6: Calculate total volume

Total volume = 242.5 mL + 1006 mL = 1248.5 mL = 1.2485 L

Step 7: Calculate molarity of NaOH

Molarity NaOH = 0.051 moles / 1.2485 L

Molarity NaOH = 0.0408 M

Step 8: Calculate pOH

pOH = -log [OH-] = -log(0.0408)

pOH = 1.39

Step 9: Calculate pH

pH = 14 - pOH

pH = 14 - 1.39

pH = 12.61

The pH of the solution is 12.61
