You have a gas that has a pressure of 2 ATM and a volume of 10 L. What would be the new volume if the pressure was changed to 1 ATM ?
Answers
Answer:
20 LExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
We have
[tex]V_2 = \frac{2 \times 10}{1} = 20 \\ [/tex]
We have the final answer as

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.

The molar mass of element X is 42.3 grams per mol and the molar mass for
element Y is Y 96.7 grams per mol. What is the empirical formula for a substance
containing a mass composition of 52.2% X and the remainder Y?
Answers
Answer:
X5Y2
Explanation:
% composition of X = 52.2%
% composition of Y = (100 - 52.2) = 47.8%
This means that there are 52.2g of X and 47.8g of Y in the compound
To calculate the empirical formula of the compound, we first convert the gram value to mole value by dividing by their molar masses.
X = 52.2g/42.3g/mol = 1.234mol
Y = 47.8g/96.7g/mol = 0.494mol
Next, we divide each mole value by the smallest value (0.494mol)
X = 1.234mol ÷ 0.494mol = 2.49
Y = 0.494mol ÷ 0.494mol = 1
We multiply each value by 2
X = 2.49 × 2 = 4.98
Y = 1 × 2 = 2
The simple ratio of X:Y is 5:2, hence, their empirical formula is X5Y2.

Determine the volume of the product containing carbon produced when 15.0 g of C2H2 are reacted with an excess of oxygen gas
Answers
Answer:
25.8 L
Explanation:
Step 1: Write the balanced equation for the complete combustion of acetylene
C₂H₂ + 2.5 O₂ ⇒ 2 CO₂ + H₂O
Step 2: Calculate the moles corresponding to 15.0 g of C₂H₂
The molar mass of C₂H₂ is 26.04 g/mol.
15.0 g × 1 mol/26.04 g = 0.576 mol
Step 3: Calculate the moles of CO₂ produced from 0.576 moles of C₂H₂
The molar ratio of C₂H₂ to CO₂ is 1:2. The moles of CO₂ produced are 2/1 × 0.576 mol = 1.15 mol.
Step 4: Calculate the volume corresponding to 1.15 moles of CO₂
At standard temperature and pressure, 1 mole of CO₂ occupies 22.4 L.
1.15 mol × 22.4 L/1 mol = 25.8 L

Answers
Answer:

Explanation:
The molar mass of a substance (Atom or molecule) is defined as the mass in grams that 1 mole of substance (6x10²³ particles of this substance) weighs. Using the periodic table of elements we can know the molar mass of each atom.
For example, the molar mass of Calcium is 40.078g / mol.
That means the mass of 1.5 moles of calcium atoms must be:
1.5 moles * (40.078g / mol) =

Useful Information,
MW of ZnO = 81.41 g
MW of CO2 = 44.01 g
135 g ZnO x (1 mol ZnO / 81.41 g ZnO) x (1 mol CO2/2 mol ZnO) x ( 44.01 g CO2 / 1 mol CO2 ) = 36.5 g CO2

how much heat is needed in order to melt one mole of that substance at its melting point
how much heat must be removed in order to freeze one mole of that substance at its freezing point
It is very important to realize that the molar enthalpy of fusion will carry a positive sign when you're dealing with melting and a negative sign when you're dealing with freezing.

During intracavitary radiation, the radioactive source is placed in a body cavity (space) , such as the rectum or uterus.
With interstitial radiation, the implants are placed in or near the tumor, but not in a body cavity. The implant procedure is usually done in a hospital operating room designed to keep the radiation inside the room. You’ll get anesthesia, which may be either general (where drugs are used to put you into a deep sleep so that you don’t feel pain) or local (where part of your body is numbed).
One or more implants is put into the body cavity or tissue with an applicator, usually a metal tube or a plastic tube called a catheter. Imaging tests (an x-ray, ultrasound, MRI, or CT scan) are usually used during the procedure to find the exact place the implant needs to go.
Before being placed, implants are kept in containers that hold the radiation inside so it can’t affect others. The health professionals handling the implants may wear special gear that protects them from exposure once the implants are taken out of the container. High-dose-rate (HDR) brachytherapy allows a person to be treated for several minutes at a time with a powerful radioactive source that’s put in the applicator. The source is removed after 10 to 20 minutes. This may be repeated twice a day over a few days, or once a day over the course of a few weeks. The radioactive material is not left in your body. The applicator might be left in place between treatments, or it might be put in before each treatment.
People getting HDR sometimes stay in the hospital if it involves multiple day treatments and if the applicator is left in place. There may be special precautions to take after the treatment, so be sure to talk to the cancer care team about this. In this approach, the implant gives off lower doses of radiation over a longer period.
Some implants are left in from 1 to a few days and then removed. You’ll probably have to stay in the hospital, sometimes in a special room, during treatment. For larger implants, you might have to stay in bed and lie still to keep it from moving.
Some smaller implants (such as the seeds or pellets) are left in place and never taken out. Over the course of several weeks they stop giving off radiation. The seeds or pellets are about the size of rice grains and rarely cause problems. If your implants are to be left in, you may be able to go home the same day they’re put in. There may be special precautions to take, so be sure to talk to the cancer care team about this.

Calculate the energy in joules of a wave particles with a wave length of 6.5×10^6 nm (infrared region)
Answers
Answer:
The energy of the wave particle is 3.058 x 10⁻²³ J.
Explanation:
Given;
wavelength of the wave particle, λ = 6.5 x 10⁶ nm = (6.5 x 10⁶) x 10⁻⁹ m
The energy of the wave particle is calculated as;
[tex]E = hf\\\\E = \frac{hc}{\lambda}[/tex]
where;
h is Planck's constant = 6.626 x 10⁻³⁴ J/Hz
c is speed of light = 3 x 10⁸ m/s
[tex]E = \frac{(6.626 \times 10^{-34})(3\times 10^8)}{6.5 \times 10^6 \times 10^{-9}} \\\\E = 3.058 \times 10^{-23} \ J[/tex]
Therefore, the energy of the wave particle is 3.058 x 10⁻²³ J.
When Svante Arrhenius first proposed his acid base theory, he was a doctoral candidate. His professors thought his ideas were unfounded. Within a decade, the Arrhenius theory of acid base was widely accepted and praised within the scientific world. Arrhenius defined acids as compounds having an ionizable hydrogen and bases as compounds with ionizable hydroxides. Eventually scientists adopted a broader theory which includes more compounds to define acids and bases. The Bronsted-Lowry acid base theory defines an acid as a _______ and a base as a ______________.

its basically represents the number of protons in the nucleus which in a neutral atom equals the number of electrons outside the nucleus and that determines the place of the element in the periodic table
