americium-241 is widely used in smoke detectors. the radiation released by this element ionizes particles that are then detected by a charged-particle collector. the half-life of 241am is 432 years, and it decays by emitting alpha particles. how many alpha particles are emitted each second by a 3.89-g sample of 241am?
Using the half-life of Am-241, its molar mass and the mass of the sample, we can calculate that it will release 3.57 * 10¹¹ α-particles each second.
If the half-life of Am-241 is 432 years, that means that in 432 years, we will have half of the starting amount, which is:
3.89 g / 2 = 1.945 g
Using the molar mass of Am-241 (241 g/mol), we can calculate the number of moles (n) in 1.945 g:
n = m/M = 1.945 g / 241 g/mol = 8.07 * 10⁻³ mol
Because each mol contains 6.022 * 10²³ particles, over 432 years we will release:
8.07 * 10⁻³ * 6.022 * 10²³ = 4.86 * 10² α-particles
Now we can calculate the number of seconds in 432 years:
432 years * 365.25 days * 24 hours * 60 minutes * 60 seconds = 1.36 * 10¹⁰ seconds
So, each second the sample of Am-241 will release:
4.86 * 10²¹ / 1.36 * 10¹⁰ = 3.57 * 10¹¹ α-particles

hydrogen has two stable isotopes, 1 1h and 2 1h, and sulfur has four stable isotopes, 32 16s, 33 16s, 34 16s, and 36 16s. how many peaks would you observe in the mass spectrum of the positive ion of hydrogen sulfide, h 2 s 1 ? assume no decomposition of the ion into smaller fragments.
There would be seven peaks if you could observe them all while considering no decomposition of the ion into smaller fragments.
Each sulfur isotope would give a peak so there are three possible combinations of the hydrogen isotopes:
H-H (m/z = 2), H-D (m/z = 3) and D-D (m/z = 4).
Thus, you will find 4 × 3 = 12 components for the molecular ion.
However, some of these peaks will overlap each other so the stable isotopes of sulfur have masses 32, 33, 34, and 36.
Thus, the expected peaks will be:
32S:m/z=34,35,36
33S:m/z=35,36,37
34S:m/z=36,37,38
36S:m/z=38,39,40
If every peak were visible, you would see seven peaks in total.
They would have m/z = 34, 35, 36, 37, 38, 39, 40.
Isotope peaks are ionic parts of the same chemical equation that are more often than not visible to different adjoining crests inferable to particles of distinctive isotopic compositions.
The number of isotope crests and the relative concentration of each crest depends on the chemical equation of the ionic part and the normal isotopic composition of its constituent components.

you cool a liquid mixture of acetic acid and water that has a mole fraction of water of 0.9. as you begin to freeze the acetic acid/water mixture, what happens to the mole fraction of water in the liquid phase?
The mole fraction of water decreases because, at this starting mole fraction, solid water forms before solid acetic acid.
What is mole fraction ?
Mole fraction represents the number of molecules of a particular component in a mixture divided by the total number of moles in the given mixture. It’s a way of expressing the concentration of a solution.
The amount fraction is another name for the mole fraction. It is the same as number fraction, which is calculated by dividing the number of molecules in a constituent (Ni) by the sum of all molecules. Instead of using a Roman x, the lowercase Greek letter chi is occasionally used to represent the mole fraction. The IUPAC recommends the letter y for gas mixtures.
Because it does not include the name of the unit mole, the National Institute of Standards and Technology of the United States prefers the phrase amount-of-substance fraction to mole fraction.
Molar concentration is a proportion of moles to volume, whereas mole fraction is a ratio of moles to moles.

a lab assistant has asked to dissolved 18.4 g of hcl is added in 662 ml of water. what is the ph of resulting solution. (assume that the volume remains constant.)
The pH value of the resulting solution is 11.9.
To calculate the pH value of the solution we need to calculate the molarity (c) of the solution, using the number of moles of HCl (n) and the volume of the solution (V = 662 mL = 0.662 L).
c = n/V
To obtain the number of moles of HCl, we are going to use the mass of HCl (m = 18.4 g) and its molar mass (M = 36.5 g/mol):
n = m/M
n = 18.4 g / 36.5 g/mol
n = 0.504 mol
Now we can calculate the molarity:
c = 0.504 mol / 0.662 L
c = 0.761 M
Because HCl is a monoprotic acid, the molarity of the solution is equal to the concentration of H⁺ ions ([H⁺] = 0.761 M), which is important for calculating pH:
pH = -log[H⁺]
pH = -log(0.761)
pH = 11.9

The bond length of the hydrogen halides will follow the order HF < HCl < HBr < HI. The radius of the Iodine atom is the largest and to form a molecule, the hydrogen atom will be farthest as compared to all hydrogen halides.
The molecule with Fluorine will have the shortest bond length because its atom has the smallest size, making them attach very closely. So the covalent bond of hydrogen fluoride will be the shortest.
The relationship between bond length and bond strength is inverse in nature. The bond length of HI is the greatest, it will have the least bond strength. So the order for bond strength of the hydrogen halides is HF > HCl > HBr > HI.
