An article about half-lives describes a parent isotope. What is a parent isotope?

A. The isotope that forms from the radioactive decay of a less stable isotope.
B. The isotope that forms from the radioactive decay of a more stable isotope.
C. The isotope that undergoes radioactive decay to form a less stable isotope.
D. The isotope that undergoes radioactive decay to form a more stable isotope.

I think the answer is D.

Answers

Answer:

D. The isotope that undergoes radioactive decay to form a more stable isotope.

Explanation:

In radioactivity, isotopes of an unstable atom disintegrates/decays into more stable ones accompanied with the emissions of certain particles e.g alpha, gamma and beta particles.

In this process, the isotope of the atom that undergoes radioactive decay to form a more stable isotope is known as the PARENT ISOTOPE while the more stable isotope that arises from the decay is called the DAUGHTER ISOTOPE.

(238, 92) Uranium → (234,90) Thorium + (4,2) Helium

In the above reaction, Uranium is the parent isotope because it decays into a more stable isotope (Thorium).

What is the initial pressure of a gas if it’s occupied a volume of 0.375 L but now occupies a volume of 1.25 L at a pressure of 95.5 K PA

Answers

Answer:

318 kPa

Explanation:

Step 1: Given data

Initial pressure (P₁): ?Initial volume (V₁): 0.375 LFinal pressure (P₂): 95.5 kPaFinal volume (V₂): 1.25 L

Step 2: Calculate the initial pressure of the gas

Assuming constant temperature and ideal behavior, we can calculate the initial pressure of the gas using Boyle's law.

P₁ × V₁ = P₂ × V₂

P₁ = P₂ × V₂ / V₁

P₁ = 95.5 kPa × 1.25 L / 0.375 L = 318 kPa

what is the atomic structure of an element that has atomic number of 11 and neutron number of 12.​

Answers

Answer:

See explanation

Explanation:

The atomic number refers to the number of protons in the nucleus, it also tells us the number of electrons in the neutral atom since the atom is electrically neutral because the number of protons and electrons are equal.

If an atom has the atomic number 11, then the electrons in the atom are arranged in the shells in the order; 2, 8, 1.

Two electrons are found in the innermost shell, eight electrons are found in the next shell and one electron is found on the outermost shell.

The nucleus of the atom is composed of a total of 23 nucleons; 11 protons and 12 neutrons.

A. HNO3 is neither an acid nor a base,
B. HNO3 is a strong acid.
C. HNO3 is a weak acid
D. HNO3 is a strong base.

Answers

Answer:

i thing its b

Explanation:

The acid dissociation constant (Ka) is a measure of the strength of an acid in solution. In HNO₃ (nitric acid), the given Ka value is 4.0 x 10⁴. It represents the equilibrium constant for the dissociation reaction of an acid in water. Therefore, option B is correct.

The dissociation constant often denoted as Kd, is a measure of the strength of the interaction between a ligand and a receptor or between a substrate and an enzyme.

A high Ka value indicates a strong acid, while a low Ka value indicates a weak acid. In this case, the Ka value of 4.0 x 10⁴ for HNO₃ is relatively high.

Answers

Answer: Pair 1 has Mg and Sr, Pair 2 has Kr and Ne, Pair 3 has As and P.

Explanation:

A periodic table is a group of elements presented in a tabular form where elements are arranged in a series of 7 rows and 18 columns.

The vertical columns are known as groups and horizontal rows are known as periods.

The elements having similar chemical properties are arranged in one group.

Magnesium (Mg) is the 12th element of periodic table placed at Group 2 and Period 3

Strontium (Sr) is the 38th element of periodic table placed at Group 2 and Period 5

Krypton (Kr) is the 36th element of periodic table placed at Group 18 and Period 4

Neon (Ne) is the 10th element of periodic table placed at Group 18 and Period 2

Arsenic (As) is the 33rd element of periodic table placed at Group 15 and Period 4

Phosphorus (P) is the 15th element of periodic table placed at Group 15 and Period 3

As magnesium and strontium are present in the same group, they will have similar chemical properties. Similarly, krypton and neon will form the second pair. Likewise, arsenic and phosphorus will form a pair.

Hence, Pair 1 has Mg and Sr, Pair 2 has Kr and Ne, Pair 3 has As and P.

Calculate the amount of heat needed to melt 89.9 g of solid methanol (CH3OH) and bring it to a temperature of 49.1C.

Answers

Answer:

20075.35 J

Explanation:

We'll begin by calculating the number of mole in 89.9 g of CH₃OH. This can be obtained as follow:

Mass of CH₃OH = 89.9 g

Molar mass of CH₃OH = 12 + (3×1) + 16 + 1

= 12 + 3 + 16 + 1

= 32 g/mol

Mole of CH₃OH =?

Mole = mass / molar mass

Mole of CH₃OH = 89.9 / 32

Mole of CH₃OH = 2.81 moles

Next, we shall determine the heat required to melt the solid methanol (CH₃OH). This can be obtained as follow:

Mole of CH₃OH (n) = 2.81 moles

Heat of fusion (Hբ) = 3.17 KJ/mol

Heat required to melt CH₃OH (Q₁) = ?

Q₁ = n × Hբ

Q₁ = 2.81 × 3.17

Q₁ = 8.9077 KJ

Converting to J

Q₁ = 8.9077 × 1000

Q₁ = 8907.7 J

Next, we shall determine the heat required to change the temperature of methanol to 49.1 °C. This can be obtained as follow:

Mass of CH₃OH (M) = 89.9 g

Initial temperature (T₁) = 0 °C

Final temperature (T₂) = 49.1 °C.

Specific heat capacity of CH₃OH (C) = 2.53 J/gºC

Heat required to change the temperature (Q₂) =?

Q₂ = MC(T₂ – T₁)

Q₂ = 89.9 × 2.53 × (49.1 – 0)

Q₂ = 89.9 × 2.53 × 49.1

Q₂ = 11167.65 J

Finally, we shall determine the total heat. This can be obtained as follow:

Heat required to melt CH₃OH (Q₁) = 8907.7 J

Heat required to change the temperature (Q₂) = 11167.65 J

Total heat required (Q) =?

Q = Q₁ + Q₂

Q = 8907.7 + 11167.65

Q = 20075.35 J

Therefore, the total heat required to melt the methanol and bring it to a temperature of 49.1 °C is 20075.35 J

Pressurized metal gas cylinders are generally used to store commonly used gases in the laboratory. At times, it can be easier to chemically prepare occasionally used gases. For example, oxygen gas can be prepared by heating KMnO4(s) according to the following chemical reaction:
2KMnO4(s) → K2MnO4(s) + MnO2(s) + O2(g)
How many grams of KMnO4 would you need to produce 0.27 moles of O2, assuming 100% conversion?

Answers

Answer:

You need 85.32 grams of KMnO₄ to produce 0.27 moles of O2, assuming 100% conversion.

Explanation:

The balanced chemical reaction is:

2 KMnO₄ (s) → K₂MnO₄ (s) + MnO₂ (s) + O₂ (g)

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles participate in the reaction:

KMnO₄: 2 molesK₂MnO₄: 1 moleMnO₂: 1 moleO₂: 1 mole

Then you can apply the following rule of three: if by stoichiometry 1 mole of O₂ is produced by 2 moles of KMnO₄, 0.27 moles of O₂ are produced by how many moles of KMnO₄?

[tex]moles of KMnO_{4} =\frac{0.27 moles of O_{2} *2moles of KMnO_{4} }{1mole of O_{2} }[/tex]

moles of KMnO₄= 0.54

The molar mass of KMnO₄ is 158 [tex]\frac{g}{mol}[/tex].

Then the amount of mass present in 0.54 moles of the compound can be calculated by:

0.54 moles* 158.034 [tex]\frac{g}{mol}[/tex]= 85.32 grams

You need 85.32 grams of KMnO₄ to produce 0.27 moles of O2, assuming 100% conversion.

What size volumetric flask would you use to create a 1.00M solution using 166.00 g of KI?

Answers

Answer:

A 1 liter volumetric flask should be used.

Explanation:

First we convert 166.00 g of KI into moles, using its molar mass:

Molar mass of KI = Molar mass of K + Molar mass of I = 166 g/mol

166.00 g ÷ 166 g/mol = 1 mol KI

Then we calculate the required volume, using the definition of molarity:

Molarity = moles / liters

Liters = moles / molarity

1 mol / 1.00 M = 1 L

Explanation:

Concentration is the amount of a substance in a predefined volume of space. The basic measurement of concentration in chemistry is molarity or the number of moles of solute per liter of solution. What is the molarity of a solution containing 9.478 grams of RuCl₃, in enough water to make 1.00 L of solution?

Step 1: Given data

Mass of RuCl₃ (solute): 9.478 gVolume of solution: 1.00 L

Step 2: Calculate the moles corresponding to 9.478 g of RuCl₃

The molar mass of RuCl₃ is 207.4 g/mol.

9.478 g × 1 mol/207.4 g = 0.04570 mol

Step 3: Calculate the molarity of the solution

We will use the definition of molarity.

M = moles of solute / liters of solution

M = 0.04570 mol / 1.00 L = 0.0457 M

What would happen to the Earth's hydrosphere if there were no atmosphere?

Answers

Weather happens in the atmosphere. However, without the hydrosphere there would be no water to evaporate. Therefore, no clouds or rain would form. The temperature of the Earth would rapidly start to rise once our atmosphere had disappeared. Without our atmosphere we have little protection from the Sun's heat. It would penetrate to the Earth's surface and cause the water to start boiling off into steam that would float off into space. Since we need water for survival, the lack of water from the hydrosphere would prevent all life source such as plants, animals, and humans from surviving.
