Consider the table below that summarizes the types of materials that can block the 3 different types of radiation. Based on the table, at which numbered spot in the table does each type of radiation belong. 1 = beta; 2 = alpha, 3 = gamma
Answers
Answer:
D. 1 = gamma; 2 = alpha, 3 = beta
Explanation:
I apologize if this answer is late, but I got answered the question right on my "Types of Radioactive Decay" quiz :)
Hope this is helpful for others! :D
Based on the table, the type of radiation belong from 1 is the gamma rays, from 2 is the aplha rays and from 3 is the beta rays.
What are radiations?During the radioactive decay process, some amount of energy is released in the form of particles and that radiations will known as alpha rays, beta rays and gamma rays.
Gamma ray are mare energetic rays and will shielded by only lead and thick concrete materials.Beta rays are less energetic than gamma rays and will shielded by lead, cloth, paper, wood, aluminium foil and thick concrete materials.Aplha rays have very less amount of energy in it and it will be shielded by all above mention materials.Hence 1 is the gamma rays, 2 is the aplha rays and 3 is the beta rays.

⦁ Find the concentration of H+, OH-, PH and POH of 0.03 M of magnesium hydroxide which ionizes to the extent of only 1 /3 in aqueous solution.
Answers
Answer:
[tex]pH=12.3\\\\pOH=1.7\\[/tex]
[tex][H^+]=5x10^{-13}M[/tex]
[tex][OH^-]=0.02M[/tex]
Explanation:
Hello there!
In this case, according to the given ionization of magnesium hydroxide, it is possible for us to set up the following reaction:
[tex]Mg(OH)_2(s)\rightleftharpoons Mg^{2+}(aq)+2OH^-(aq)[/tex]
Thus, since the ionization occurs at an extent of 1/3, we can set up the following relationship:
[tex]\frac{1}{3} =\frac{x}{[Mg(OH)_2]}[/tex]
Thus, x for this problem is:
[tex]x=\frac{[Mg(OH)_2]}{3}=\frac{0.03M}{3}\\\\x= 0.01M[/tex]
Now, according to an ICE table, we have that:
[tex][OH^-]=2x=2*0.01M=0.02M[/tex]
Therefore, we can calculate the H^+, pH and pOH now:
[tex][H^+]=\frac{1x10^{-14}}{0.02}=5x10^{-13}M[/tex]
[tex]pH=-log(5x10^{-13})=12.3\\\\pOH=14-pH=14-12.3=1.7[/tex]

Container 1 particles have lower average kinetic energy and higher temperature than Container 2 particles.
Explanation:
Kinetic energy is the speed of the particles in the bottle.
As you can see in the illustration below, the patricles in Picture 2 are moving faster than the ones in Picture 1.
The tempature of Container 1 is higher because all of the particles are sitting on top of one another. Not being able to move, their pressure builds up and creates heat.

What is the pH of a solution that has [H+] of .0042M?
Answers
Answer:
pH = 2.4
Explanation:
pH is defined as the negative log of the hydronium concentration.
Thus, we can plug in the given hydronium concentration:
pH = -log[H⁺] = -log[0.0042] = 2.4 (two significant figures)
The pH of the solution is 2.4.
P.S: Although I referred to [H⁺] as hydronium concentration, it is more accurate to express it as [H₃O⁺], though they are interchangeable and means the same thing.
In test tube 3, 3 mL of .002 M Fe(III) solution is combined with 7 mL of .02 M 5-sulfosaliclic acid (SSA) solution. What is the mole fraction of SSA in the test tube
Answers
Answer:
0.96
Explanation:
Number of moles of Fe(III) = 3/1000 * 0.002 M = 6 * 10^-6 moles
Number of moles of SSA = 7/1000 * 0.02 = 1.4 * 10^-4 moles
Total number of moles = 6 * 10^-6 moles + 1.4 * 10^-4 moles
Mole fraction of SSA = number of moles of SSA/ total number of moles.
Mole fraction of SSA = 1.4 * 10^-4 moles/ 6 * 10^-6 moles + 1.4 * 10^-4 moles
Mole fraction of SSA = 0.96

350.0 ML of air is at 23.0°C what is the volume at 90.0°C
Answers
Answer:
V=0.430 Liters
Explanation:
First off you need to convert ml to l and celsius to kelvin, in order for them to be in the S.I.
So, 350.0mL is 0.350 L and 23.0 C is (273.15+23=) 296.15 K (you can ignore the 0.15)
From the equation pV=nRT, lets name this equation (1), we can tell that the number of moles, pressure, and R, stay the same. The only thing changing is the volume, and temperature.
With the information given, let's figure out the pressure. From equation (1) if we solve it for the pressure of the gas, p=nRT/V => p=nR*296.15/0.350 => p=846.15 *nR
Now, we have to figure out the volume of the gas at 90.0 C (363.15 K), and solve equation (1) for volume, using the pressure we previously found.
v=nRT/p => v=nR*363.15/846.15*nR => (the nR's from top and bottom go away) v=0.429 L
Since we used 273.15 for the conversion of celsius to Kelvin, we could round up the number to
V=0.430 Liters

It take 38.70cm³ of 1.90 NaO4 to neutralize 10.30cm³ of H2So4 in a battery. Calculate the molar concentration of H2So4
Answers
Answer:
The molar concentration of base Cb = 14.2777M
Explanation:
Volume of acid Va = 38.70cm^3,
Concentration of acid NaO4 C_a= 1.90M
Volume of Base Vb = 10.30cm^3
Also, Equation of the reaction
H2SO4 + 2NaOH = Na2SO4 + 2H2O
No of mole of acid Na = 1
No of mole of base Nb = 2
CaVa/CbVb = Na/Nb
Cb = CaVaNb/VbNa
Cb = 1.9×38.7×2/(10.30×1)
Therefore, Cb = 14.2777M
The molar concentration of base Cb = 14.2777M
