A supervisor spends a day inspecting a nuclear plant for potential radiation leaks. She has to move throughout the plant inspecting all the equipment and machinery. She needs to take two different radiation detection devices to help ensure her safety and to find radiation leaks. She needs the results immediately. Which two devices would be the best choices for the task?
Answers
Answer:
Geiger-Mueller tube or Geiger counter and a Personal Radiation Detector (PRD).
Explanation:
In order to immediately detect traces and signs of radiation leaks in the nuclear power plant, the supervisor must use two devices that readily give its results. These devices could be a Geiger-Mueller tube or Geiger counter and a Personal Radiation Detector (PRD). A PRD has a very fast response time, while a Geiger counter also displays results real time.

number of moles = 3.94 / 63.0 => 0.0625 moles
Volume = moles / molarity
V = 0.0625 / 1.50
V = 0.04166 L x 1000 = 41.66 mL

Final answer:
To dissolve a 3.94g copper penny, we would need approximately 331 milliliters of 1.50 M HNO3, taking into consideration the stoichiometry of the copper-nitric acid reaction.
Explanation:
Stoichiometry is required to solve this chemistry problem. The balanced equation for the reaction between copper and nitric acid is: 3Cu(s) + 8HNO3(aq) → 2NO(g) + 3Cu(NO3)2(aq) + 4H2O(l)
From this, we can conclude that every mole of copper reacts with eight moles of nitric acid. The molecular weight of copper is approximately 63.546 g/mole, so the moles of copper in an old penny can be calculated by mass (3.94 g) divided by the molar mass (63.546 g/mol).
This calculation shows that there are approximately 0.062 moles of copper in a penny. Since we determined that eight moles of nitric acid are required to react with one mole of copper, eight times the moles of copper gives the moles of nitric acid required, which is 0.496 moles.
Since molarity (M) = moles/liters, we can find out the volume of 1.50 M HNO3 required by rearranging the formula to be Liters= moles/Molarity. So, 0.496 moles divided by 1.50 M gives roughly 0.331 liters, which can be converted to approximately 331 milliliters.

The balanced equation is 2 C₄H₁₀ + 13 O₂ → 8 CO₂ + 10 H₂O.
The balanced chemical equation for the combustion of butane is:
2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O. Therefore, option C is correct.
This equation represents the combustion of butane in the presence of oxygen to produce carbon dioxide and water.
The equation shows that 2 molecules of butane react with 13 molecules of oxygen gas. On the left side of the equation, we have a total of 8 carbon atoms and 20 hydrogen atoms.
On the right side of the equation, 8 molecules of carbon dioxide (each with 1 carbon atom) and 10 molecules of water (each with 2 hydrogen atoms).

Determining the number of atoms in a jar of liquid task most likely involves a calculation that uses moles.
What do you mean by mole ?
The term mole is defined as a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.
A mole is the amount of material including 6.023 × 10²³ particles. 1 mol = 6.023 × 10²³particles. This number is also called Avogadro's number.
In determining the number of atoms that makes up a substance, the number of moles is very necessary.
The mole is the favorable unit of quantity of particles. It can be likened to a quantity of things in everyday life like a dozen, a score and a gross.
A mole of any substance contains 6.023 x 10²³ particles
These particles can be atoms, protons, neutrons, electrons etc.
Thus, to find the number of atoms, we must know the number of moles.
