Answer 1

Energy released in the reaction in which a proton fuses with a neutron to form a deuterium nucleus is calculated as 2.234 MeV.

What do you understand by a fusion reaction?

In fusion reaction, two light nuclei merge to form single heavier nucleus. The process releases energy because total mass of the resulting single nucleus is less than the mass of two original nuclei. And the leftover mass becomes energy.

form a deuterium nucleus: 1^1H+0^1n⟶1^2H+γ The masses are 1^1H(1.0078u) 0^1n(1.0087u) and 1^2H(2.0141u) the γ -ray photon is massless.

The rate of effusion of a particular gas was measured and found to be 21.0 mL/min. Under the same conditions, the rate of effusion of pure methane (CH4) gas is 47.0 mL/min. What is the molar mass of the unknown gas

Answers

the particular gas effusion was 21.0. and the methane effusion rate is 47.0 The molar mass of the unknown gas is approximately 28.6 g/mol

The process through which a gas manages to escape through with a small hole or highly permeable barrier is known as effusion. A gas's rate of effusion is inversely proportional to its molar mass squared. The following equation describes this relationship: rate1 / rate2 = (sqrt(molar mass2) / sqrt(molar mass1)). where rate1 and rate2 are the rates of effusion of the two gases and molar mass1 and molar mass2 are the molar masses of the two gases.Given the rate of effusion of the unknown gas is 21.0 mL/min, and the rate of effusion of pure methane (CH4) is 47.0 mL/min, we can use the above equation to find the molar mass of the unknown gas:

(21.0 mL/min) / (47.0 mL/min) = sqrt(molar mass unknown) / sqrt(16.04 g/mol)

Squaring both sides of the equation, we get:

(21.0 mL/min)^2 / (47.0 mL/min)^2 = (molar mass unknown) / (16.04 g/mol)

Solving for molar mass unknown we get:

molar mass unknown = (16.04 g/mol) * (21.0 mL/min)^2 / (47.0 mL/min)^2

The molar mass of the unknown gas is approximately 28.6 g/mol

Please note that the above calculation is based on the assumption that the temperature and pressure are the same for both gases and that the gases are ideal

A 5.05 g sample of quartz (SiO 2) contains 2.36 g of silicon. What are the percentages of silicon and oxygen in quartz

Answers

In quartz, silicon has a mass percent of 46.7% while oxygen has a mass percent of 53.3%.

Given the total mass of a sample of quartz (SiO2) (m1) = 5.05g

Mass of silicon (m2) = 2.36g

The percent composition of an element in a chemical compound is referred to as mass percent. Mass percent may be expressed as follows:

mass percent  = mass of element/mass of sample x 100

The percent mass of silicon (p1)  =  2.36/5.05 x100 = 46.7%

The substance was made of silicon and oxygen.

Thus, 100% Quartz =%Silicon +%Oxygen can be used to express the mass percentage of quartz.

100% Quartz = 46.7% + % Oxygen

% Oxygen = 53.3%

Answers

The molecular weight of the unknown compound is 80.864g.

Give a definition of freezing point depression.

Only the solute's concentration affects freezing point depression; the solute's mass or chemical composition have no bearing. When it's cold outside, salt is often used to prevent ice from forming on roads by lowering the freezing point of water.

Depression in freezing point is Kb x m

T(f) - T  = Kb x  m

48.1 - 35.8 =  9.8 x m

m = 1.255

m = moles of solute x 1000/mass of solvent

moles of solute x 1000 / 10.0090  = 1.255

moles of solute = 0.0125

moles = mass / molar mass

1.0108  / molar mass  = 0.0125

molar mass =  1.0108 / 0.0125

molar mass = 80.864

the half life of the isotope of uranium of mass number 234 grams is 2.5 * 10^5 years . how long after isolation of a sample of this isotope will only one sixth of the original mass be left

Answers

AThe half-life of an isotope is the amount of time it takes for half of the atoms in a sample to decay. If the half-life of a sample of uranium-234 is 2.5 * 10^5 years, it means that after 2.5 * 10^5 years, half of the atoms in the sample will have decayed.

If you want to know how long it will take for only one sixth of the original mass to be left, you can use the following formula:

t = (half-life) * log(2) / log(1/6)

Plugging in the values, we get:

t = (2.5 * 10^5 years) * log(2) / log(1/6)

This simplifies to:

t = 3.7 * 10^5 years

So it will take approximately 3.7 * 10^5 years for only one sixth of the original mass to be left.nswer:

How can light help us understand atoms?

Answers

Answer: We can calculate the energy levels of an atom

Explanation:

Spectral lines tell us how many different energy levels an atom has, and how far apart those energy levels are spaced.This is possible because spectral lines are the result of an excess (emission lines) or deficiency (absorption lines) of observed photons emitted from certain types of matter. The lines are caused by electrons moving between energy levels within individual atoms. Since each element emits it's own unique spectrum, this means that different types of atoms must have a distinct number of electrons in very particular energy levels.

Explain the relationship between an element's row number in the periodic table and the highest principal quantum number in the element's electron configuration. How does this relationship differ for main-group elements, transition elements, and inner transition elements

Answers

The row number in the periodic table corresponds to the highest principal quantum number (n) in the element's electron configuration, also known as the element's valence shell.

Difference between relationship of main-group elements, transition elements, and inner transition elements.

For main-group elements, the highest principal quantum number increases from n = 2 in the first row to n = 3 in the second row and n = 4 in the third row. This means that main-group elements in the first row have their valence electrons in the 2nd energy level (n=2), elements in the second row have their valence electrons in the 3rd energy level (n=3) and elements in the third row have their valence electrons in the 4th energy level (n=4).

Transition elements have electron configurations that deviate from this pattern, they have electrons in higher energy level (n>3) but these electrons are not in the valence shell. They have a different valence electron configuration which allows them to exhibit multiple oxidation states, and also they have a d-block in their electron configuration

Inner transition elements also deviate from this pattern, they also have electrons in higher energy level (n>3) but these electrons are not in the valence shell.

The standard enthalpy of formation (ΔHf) for methane is -74.8 kJ/mol, for carbon dioxide it is -393.5 kJ/mol, and for water it is -285.8 kJ/mol. The standard enthalpy of formation is the change in enthalpy when one mole of a compound is formed from its elements in their standard states.

To calculate the standard enthalpy of reaction (ΔHrxn), we need to use the equation:

ΔHrxn = ΣΔHf (products) - ΣΔHf (reactants)

Plugging in the values for the reactants and products, we get:

ΔHrxn = (2 * -285.8 kJ/mol) + (-393.5 kJ/mol) - (-74.8 kJ/mol)

ΔHrxn = -890.2 kJ/mol

This reaction is exothermic because the value of ΔHrxn is negative. Exothermic reactions release heat, while endothermic reactions absorb heat.
