amu. The first two isotopes have relative abundances of 76.12% and 10.27% and masses of 81.6643 amu and
81.1239 amu respectively. What is the mass of the third isotope?

- report your answer in six significant figures
- do not include units

Answers

Answer 1

The average atomic mass  for the new element is given 81.5529 amu. The percentage abundance for the third isotope is 13.6 %. Then its atomic mass is 83.9 amu.

What are isotopes?

Isotopes are atoms of same element with different atomic mass numbers. Almost all elements have two or more isotopes but not all of them are stable in nature.

The average atomic mass can be calculated from the isotopic mass and and percentage abundance as follows:

atomic mass = ∑ (isotopic mass × %abundance /100 )

Apply the isotopic mass and abundance of all isotopes given as follows:

atomic mass of the element = (76.12/100 ×81.6643 amu) +  (10.27/100 × 81.1239 amu)  +  (13.6 /100 × X amu) =81.5529 amu.

Then,

(13.6 /100 × X amu) = 70.41 amu.

X  = 83.9 amu.

Therefore, the atomic mass of the third isotope is 83.9 amu.

What are atoms?

An atom is the basic unit of matter and the defining structure of elements. The term "atom" comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided.

Atoms are composed of a nucleus, which contains positively charged protons and uncharged neutrons, surrounded by a cloud of negatively charged electrons. The number of protons in an atom's nucleus determines what element the atom is, as each element has a unique number of protons.

To count the number of atoms in the formula 2Ca(OH)2, we need to determine the number of each type of atom present.

In this formula, there are:

2 calcium atoms (Ca)4 oxygen atoms (O)4 hydrogen atoms (H)

So, the total number of atoms in the formula is 2 + 4 + 4 = 10 atoms.

For a given mass of gas at a constant temperature, when volume decreases pressure increases.

For at a constant temperature, when mass decreases pressure increases.

What is the effect of a decrease in volume on the pressure of gases?

According to Boyle's Law, at a constant temperature, the pressure of a gas is inversely proportional to its volume.

Thus, a decrease in the volume of a gas will result in an increase in pressure, assuming that the temperature and amount of gas remain constant.

Assuming that the temperature and volume remain constant, an increase in the mass of a gas will result in an increase in its pressure. This is because as the mass of the gas increases, the number of gas particles also increases, which leads to an increase in the frequency and force of their collisions with the container walls. These increased collisions result in an increase in the pressure of the gas.

What mass of HCl is contained in 45.0 mL of an aqueous HCl solution that has a density of 1.19g cm ^ - 3 and contains 37.21% HCl by mass?​

Answers

Answer:

0.01999 g

Explanation:

To find the mass of HCl in 45.0 mL of the solution, we need to first find the volume of the solution and then convert that volume to mass.

First, we can convert 45.0 mL to liters by dividing by 1000:

45.0 mL ÷ 1000 = 0.045 L

Next, we can find the mass of the solution by multiplying the volume by the density:

0.045 L × 1.19 g/cm³ = 0.05365 g

Now that we have the mass of the solution, we can find the mass of HCl by multiplying the mass of the solution by the concentration of HCl expressed as a decimal:

0.05365 g × 0.3721 = 0.01999 g

So, there is approximately 0.01999 g of HCl in 45.0 mL of the solution.

Answers

Answer:

Explanation:

Quantum numbers are a set of numbers that describe the state of an electron in an atom. There are four types of quantum numbers:

Principal quantum number (n): This quantum number determines the energy level of an electron in an atom. The larger the value of n, the higher the energy level and the farther the electron is from the nucleus.

Azimuthal quantum number (l): This quantum number determines the shape of the electron orbital. The value of l can range from 0 to n-1, and it describes the angular momentum of the electron.

Magnetic quantum number (m): This quantum number determines the orientation of the electron orbital in space. The value of m can range from -l to +l, and it describes the orientation of the orbital.

Spin quantum number (s): This quantum number describes the intrinsic angular momentum, or spin, of an electron. The value of s is always ±1/2.

These four quantum numbers together describe the state of an electron in an atom, including its energy, shape, orientation, and spin. Understanding these quantum numbers is essential for understanding the behavior of electrons in atoms and for predicting the properties of chemical compounds.

Answers

Answer:

The molarity of a solution can be calculated by dividing the number of moles of solute by the volume of the solution in liters. To calculate the number of moles of solute in a solution, we first need to find the mass of the solute.

Since the concentration of the phosphate sample is given in mg/L (ppm), we can convert this to grams by multiplying by 0.001:

93.1 mg/L x 0.001 g/mg = 0.0931 g/L

Next, we can find the number of moles of solute by dividing the mass of solute by its molar mass:

0.0931 g ÷ (1 mol/94 g) = 0.000989 mol/L

Finally, we can find the molarity of the solution by dividing the number of moles of solute by the volume of the solution:

0.000989 mol ÷ (1 L) = 0.000989 M

2. Co2+(aq) + Al(s) → Al3+(aq) + Co(s)
3. Cd(s) + Pb2+(aq) → Pb(s) + Cd2+(aq)
4. Al3+(aq) + Cr(s) → Cr3+(aq) + Al(s)
5. All of the listed reactions will occur.

Answers

Answer:

Explanation:

According to the activity series of metals, the reaction that would not be expected to occur is:

Al3+(aq) + Cr(s) → Cr3+(aq) + Al(s)

This is because aluminum (Al) is higher on the activity series and is less likely to be oxidized (lose electrons), while chromium (Cr) is lower on the activity series and is more likely to be oxidized. In this reaction, aluminum would have to be oxidized, which is not consistent with its position on the activity series.

All of the other reactions listed are expected to occur because they involve the transfer of electrons from a metal that is lower on the activity series to a metal that is higher on the series.

Answers

Yes, it is possible to identify the liquid, and the density of the liquid is closest to 0.889 g/cm³ so the liquid is most likely tetrahydrofuran.

To calculate the density of the unknown liquid, we use the formula:

Substituting the given values, we get:

Density = 682. g / 0.767 L

Density = 888.5 g/L

Rounding to three significant digits, the density of the unknown liquid is 889 g/L.

Using the information provided in the question, we can compare the density of the unknown liquid to the known densities of the listed chemicals. The densities (in g/cm³) of the chemicals are:

Dimethyl sulfoxide: 1.092

A (g) ⇌ 2 B (g)

Answers

If a reaction vessel is charged with 0.50 atm of A and 0.130 atm of B. Once the reaction reaches equilibrium,  the equilibrium partial pressure of B is:  5.79 atm.

What is the equilibrium partial pressure of B?

To calculate the equilibrium partial pressure of B, we need to use the expression for an equilibrium constant (Kp). The equation for Kp for a reaction of the form A (g) ⇌ 2 B (g) is given by:

Kp = (P_B^2) / (P_A)

Where:

P_A and P_B are the equilibrium partial pressures of A and B, respectively.

Given that the initial pressures of A and B are 0.50 atm and 0.130 atm, respectively, and the value of Kp is 67.2, we can use the above equation to calculate the equilibrium partial pressure of B:

Kp = (P_B^2) / (P_A) = 67.2

P_A = 0.50 atm

Therefore,

(P_B^2) / (0.50 atm) = 67.2

P_B^2 = 67.2 * 0.50 atm = 33.6 atm

P_B = √(33.6 atm) = 5.79 atm

So, the equilibrium partial pressure of B is approximately 5.79 atm.

An adaptation that is useful for living in one type of environment may be useless in a different environment. Organisms must live in a place that has the conditions they need to survive. Organisms generally have adaptations that allow them to survive in one particular enviroment.

What do adaptations in a particular enviroment mean?

The expression adaptations in a particular enviroment mean that these traits are only advantageous regarding the enviroment.

Therefore, with this data, we can see that the adaptations in a particular enviroment can be detrimental or beneficial depending on the enviroment.
