What does a half-life of 30 minutes mean?

Answers

Answer 1

A half-life of 30 minutes after the drug administration, 25 mg of the drug remains in the body.

In radioactivity, the half-life is the period of time needed for half of a radioactive sample's atomic nuclei to spontaneously decay (convert into different nuclear species by emitting particles and energy) or, more precisely, the period of time needed for a radioactive material's rate of disintegrations per second to decrease by half. An example of a radioactive isotope with a long half-life is cobalt-60, which is utilised in radiotherapy. A sample that contained 8 g of cobalt-60 when it was first prepared would now only contain 4 g of the metal after that time period, and it would produce half as much radiation. The sample would only contain 2 g of cobalt-60 after an additional 5.26-year delay

Answers

Answer:

The equation that violates the Law of Conservation of Matter is 5 HI + 2 HIO3 --> 3 12 + 3 H₂O

Explanation:

This equation shows the formation of three molecules of iodine (I2) from two molecules of hydrogen iodate (HIO3) and five molecules of hydrogen iodide (HI), but it does not account for the atoms of iodine that are used to form the three molecules of iodine. According to the Law of Conservation of Matter, the total number of atoms of each element must be the same on both sides of a chemical equation, but in this equation, there are more atoms of iodine on the left-hand side than on the right-hand side. This means that the equation is not balanced, and it violates the Law of Conservation of Matter. The other equations listed are balanced and do not violate this law.

The force that a fluid applies against a wall—hydrostatic pressure—is essentially moves fluid between compartments. The pressure that blood applies to the blood vessel walls as a result of the heart's pumping motion is known as the hydrostatic pressure of blood. The opposing "colloid osmotic pressure" in capillaries is greater than the blood's "constant" pressure, which is principally created by the circulation of albumin at the capillary's arteriolar end. This pressure pushes plasma and nutrients into the surrounding tissues from the capillaries.

A covalent bond is formed when two atoms exchange one or more pairs of electrons. The two atomic nuclei are concurrently drawing these electrons to them. When the difference between the electronegativities of two atoms is too tiny for an electron transfer to take place to create ions, a covalent bond is formed.

What is the molarity of 40g of NaOH dissolved in 1.25 Litre of water?

Answers

0.8 M is the molarity of 40g of NaOH dissolved in 1.25 Litre of water

To find the molarity of solution we will use following expression ;

Molarity (M) = n/V(ml)×1000

Where, n = number of moles of solute

            V = volume of solution in ml.

In the given problem,

NaOH is Solute in solution

Given mass of sodium hydroxide = 40 grams

Molar mass of NaOH = 40 g/mol

Total volume of the solution = 1.25 L

Number of moles of sodium hydroxide(n):-

n = mass of NaOH/molar mass of NaOH            

n = 40g/(40g/mo)l

n = 1 mole of NaOH

Substitute the values of volume and number of moles of solution in the molarity formula,

Molarity (M) = 1mole/1.25 L

why did the big bang not produce a significant proportion of elements heavier than helium?

Answers

The big bang did not produce a significant proportion of elements heavier than helium because the temperatures and densities present in the early universe were not sufficient to support the fusion of heavier elements.

During the first few minute of the big bang, the universe was composed of mostly hydrogen and helium, with very small amounts of lithium and beryllium. As the universe expanded and cooled, the denser regions of the universe collapsed to form the first stars. Inside these stars, the intense pressure and heat generated by nuclear fusion reactions allowed for the production of heavier elements, such as carbon and oxygen. However, elements heavier than helium, such as iron and nickel, require even higher temperatures and densities to be produced, which can only be found in the cores of supernovae.

Answers

The gas sample is CHCl₃ having molar mass of 119.135 g/mol.

Calculate the molar mass of the gas, by using the equation given by Ideal gas equation,

PV = nRT

PV = w/M RT

Where,

P = Pressure of the gas = 850 torr

V = Volume of the gas = 0.918 L

w = Weight of the gas = 4.84 g

M = Molar mass of gas = ?

R = Gas constant = 62.36 L

T = Temperature of the gas = [35 + 273] K = 308 K

Substituting the values we get,

850 torr × 0.918 L = 4.84 g/ M × 62.36 L × 308 K

⇒ M = (4.84 g× 62.36 L × 308 K) / (850 torr × 0.918 L)

Answers

Option (a) is correct. If a reaction is at equilibrium and we will increase the volume of the reaction then the Reaction will shift to the right in the direction of product.

The Reaction is,

2H2S(g) + 3O2(g) ----> 2H2O(g) + 2SO2(g) a)

According to Le Chatelier's principle, if a dynamic equilibrium is disturbed by changing the conditions the position of equilibrium shifts to counteract the change to reestablish an equilibrium. If a chemical reaction is at equilibrium and experiences a change in pressure, temperature or concentration of products or reactants, the equilibrium shifts in the opposite direction to offset the change. A change in one of the variables that describe a system at equilibrium produces a shift in the position of the equilibrium that counteracts the effect of this change.

We are increasing pressure here. Reaction will try to decrease the pressure. Hence it will move in a direction which have lesser gaseous molecules. Here product has less gaseous molecule. So equilibrium will move to right. Equilibrium moves to product side.

red mineral is placed in the cylinder,
displacing the level to 35.0 mL.
What is the volume of the red
mineral piece in milliliters?
volume = [?] mL

Answers

The volume of the red mineral piece in millilitres is 10 millilitres.

How to calculate volume?

Volume in chemistry is a measure of the amount of space that matter occupies.

Matter is defined as a physical substance that occupies space and has a mass. In physical sciences like chemistry, the standard unit of volume is cubic metres (m³). From this unit, other units are derived including litre (L) and millilitre (mL).

According to this question, a graduated cylinder is filled to 25.0 mL with water and a piece of a red mineral is placed in the cylinder, displacing the level to 35.0 mL.

This suggests that the volume of the red mineral placed in the cylinder can be calculated as follows:

Volume of red mineral = 35.0mL - 25.0mL = 10.0mL

Therefore, 10mL is the volume of the piece of red mineral.
