the half-life of cesium-137 is 30 years. suppose we have a 70-mg sample. (a) find the mass that remains after t years.

Answers

Answer 1

70/ 2(t/30) mg is the mass that remains after t years, the half-life of cesium-137 is 30 years. suppose we have a 70-mg sample.

Now we have to calculate the mass that remains after 't' years.

As we are given that,

a o= 70 mg

t 1/2= 30 years

Now put all the given values in formula , we get:

a=a0/2(t/t/2)

a= 70/2(t/30) mg

The delicate, golden-colored metal caesium is immediately attacked by air and reacts violently with water. As a drilling fluid, caesium compounds are most frequently used. Additionally, they are employed to produce special optical glass, as a catalytic promoter, in vacuum tubes, and radiation detection apparatus. The universal time standard is also a result of cesium isotopes. Because of this, they are utilised in atomic clocks for cell phone networks, the internet, GPS, and aviation guiding systems.

Answers

CO ligands is most likely to form a low-spin octahedral complex with iron(iii).  The energy difference between high and low spin is determined by the ligand mix and coordination stereochemistry.

For these model compounds, high spin optimised geometries yield structures with octahedral symmetry. D5 low spin will form an octahedral complex. Three of the five d orbitals will be filled with electrons, while the other two will be energy. These two empty low-spin can be sp3d2 hybridised (or d2sp3 hybridised) to form an octahedral complex.

what is the 15th percentile of chloride concentration values? (round your answer to four decimal places.)

Answers

3.97 mmol/L is the 15th percentile of chloride concentration values of blood chloride.

The 15th percentile of a normal distribution corresponds to the value of chloride below which 15% of the data lies. To determine this value for a normal distribution with a mean of 5 and a standard deviation of 1, we can use the standard normal distribution table or a calculator that can compute percentiles for a normal distribution.

Using a standard normal distribution table, we can find that the 15th percentile of a normal distribution with a mean of 0 and a standard deviation of 1 is -1.03. Since the mean of our distribution is 5 and the standard deviation is 1, we need to shift the value by 5 units to the right to find the 15th percentile of our distribution. Therefore, the 15th percentile value of chloride concentration is -1.03 + 5 = 3.97 mmol/L.

Alternatively, we can use a calculator that can compute percentiles for a normal distribution. For example, using the "NormDist" function in Microsoft Excel, we can calculate the 15th percentile value as follows:

=NORMDIST(3.97,5,1,TRUE)

This will return a value of 0.15, which indicates that the value of 3.97 mmol/L is the 15th percentile of the normal distribution.

It's important to note that this calculation assumes that the data follows a normal distribution. If the data is not normally distributed, the 15th percentile value may be different.

Answers

The [OH-] of the 0.025 M weak acid solution will be equal to the pKA of the acid, 4.615.
What is weak acid solution?
A weak acid solution is a solution that contains an acid that is not completely ionized in water. Weak acids, such as acetic acid, have pH values between 4.5 and 6.0. These acids are not strong enough to completely break apart in water, leaving some of the molecules still intact. Because of this, weak acids form molecules that can react with other molecules, such as bases, in solution.
This is because the equilibrium of the acid dissociation reaction is reached with the same concentration of acid and its conjugate base in solution. The [H3O] will be equal to 0.025 M, as the acid is in dissociation equilibrium with its conjugate base. The pH of the solution can be calculated by taking the negative log of the [H3O], which will be 1.59. The pOH can be calculated by taking the negative log of the [OH-], which will be 4.615.

Formula and Pressure's Unit:

Thrust/Area = Pressure (P)

Pascals (Pa) is the SI unit. 1 Pa = 1N/m2

For instance, it is simpler to hammer a sharp pin than dull pin. This is due to the fact that sharp pin's end has a lower surface area than blunt pin. This causes the pressure to rise.

Concentrated nitric acid and copper react to produce hydrogen gas, nitrogen dioxide gas, and copper (II) nitrate according to the following equation:

[tex]Cu + 4HNO_3 --- > Cu(NO_3)_2 + 2H_2 +2NO_2[/tex]

The mole ratio of copper the nitric acid is 1:4.

I g of copper is equivalent to:

              A0 is the initial amount of decomposed substance at t = 0,

               k is the constant of decay

               t is the time elapsed

              A(t) is the amount after time t.

First order reaction is one in which the rate of reaction is proportional to the concentration of the reactant. It doubling the concentration doubles the reaction rate. A first-order reaction can have one or two reactants as in the case of the decomposition reaction. The percentage of decomposed compound left after a time t is, [A(t)], divided the the initial amount, [A0], time 100, or

A = A0e-kt

A/A0 = e-0.00299t, [k = 0.00299, divide both sides by A0]
