A Geiger counter used in several applications over the course of a typical day produces on the average 100 counts per second. The tube is in the form of a cylinder 5 cm in diameter by 20 cm long and is filled with a mixture of 90% argon and 10% ethanol to a pressure of 0.1 atmosphere. In the Geiger-Muller region, each output count results from the formation of about 1010 ion-electron pairs. How long will it take for one-third of the quenching gas to be used up, thus necessitating replacement of the tube

A certain shade of blue has a frequency of 7.08×1014 Hz. What is the energy of exactly one photon of this light? Planck's constant ℎ=6.626×10−34 J⋅s.
Answers
Answer:
We have the final answer as
[tex]4.69 \times {10}^{ - 19} \: \: J[/tex]
Explanation:
To find the energy of a photon of this light we use the formula
E = hfwhere
E is the energy
f is the frequency
h is the Planck's constant which is
6.626 × 10-³⁴ Js
From the question
f = 7.08×10¹⁴ Hz
We have
E = 7.08×10¹⁴ × 6.626 × 10-³⁴
We have the final answer as
[tex]4.69 \times {10}^{ - 19} \: \: J[/tex]

What volume of hydrogen is formed when 3.00 g of
magnesium react with an excess of dilute sulfuric acid is
carried out under room temperature and pressure at 1 atm.
Answers
Answer:
Volume of hydrogen gas formed = 3.1 L
Explanation:
Given data:
Mass of magnesium = 3.00 g
Temperature = room = 27°C (27+273 = 300 K)
Pressure = 1 atm
Volume of hydrogen gas formed = ?
Solution:
Chemical equation:
Mg + H₂SO₄ → MgSO₄ + H₂
Number of moles of Mg:
Number of moles = mass/molar mass
Number of moles = 3.00 g/ 24 g/mol
Number of moles = 0.125 mol
Now we will compare the moles Mg with hydrogen.
Mg : H₂
1 : 1
0.125 : 0.125
Volume of hydrogen:
PV = nRT
1 atm × V = 0.125 mol × 0.0821 atm.L /K.mol × 300 k
V = 3.1atm.L/1 atm
V = 3.1 L

Predict the change in enthalpy (AH) of this reaction.
A) AH is (-); endothermic
B) AH is (+); endothermic
C) AH is (-); exothermic
D) AH is (+); exothermic
E) AH = 0; thermoneutral
Answers
Answer:
Option B: ΔH is (+); endothermic
Explanation:
From the reaction Cl2 → 2Cl(g) given, we can see that the number of moles on the left hand side is 1 while on right hand side, it is 2. This means the number of moles are increasing and it means that the randomness of the system has increased. Also, the bonds are being broken down.
Therefore, the reaction is endothermic. In endothermic reactions, ΔH is positive.
Thus, the correct option is option B.

What is the end
result of a chemical reaction?

Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
The end of a chemical reaction is the product.
What is a chemical reaction?
A chemical reaction contains a reactant that reacts to form products. The reactant can be more than two, and the product can be two or more.
Food spoiling is a chemical reaction because it has an unpleasant odor, taste, and color change. Fruits undergo a chemical shift as they ripen. For instance, both the texture and color may change.
When we balance a chemical process, the number of moles or atoms on the left must match the amount on the right. Thus, the atoms participating in such a chemical process are discovered to have mass.
Chemical elements are uncontaminated by impurities or other elements and are pure substances made up of just one type of atom. They are found in the crust of the earth. Carbon, hydrogen, and oxygen are some examples.
Therefore, the end is the product.
