you wish to make a 0.286 m hydrochloric acid solution from a stock solution of 3.00 m hydrochloric acid. how much concentrated acid must you add to obtain a total volume of 50.0 ml of the dilute solution?

Answers

Answer 1

It will require 5 ml of concentrated acid to obtain a total volume of 50.0 ml of the dilute solution

formula for dilution calculations, which is :

                                      C₁V₁ = C₂V₂,

where C₁ is the concentration of the concentrated acid,

V₁ is the volume of the concentrated acid,

C₂ is the concentration of the dilute acid, and

V₂ is the final volume of the dilute acid,

The formula values are as follows:

                                V₁ = (C₂V₂)/C₁ V₁

                    = (0.286 M × 0.05 L)/3.00 M V₁

                                     = 0.005 L = 5 ml

Therefore, 5 ml of concentrated acid will be required to produce a total volume of 50.0 ml of the diluted solution.

What kinds of dilution exist?

A common method for achieving this concentration reduction is serial dilution. The rate at which a gas becomes diluted can be determined using the dilution equation. A type of illegal trademark use outside of the relevant market is known as trademark dilution.

What does the dilution procedure do?

The reference for antimicrobial susceptibility testing is the dilution process, which is used to demarcate the minimal inhibitory concentration of an antimicrobial to inhibit or kill bacteria or fungi.

a mixture contains 0.250 mol of fe and 1.20g of c. what is the total number of atoms in the mixture?

Answers

If a mixture contains 0.250 mol of fe and 1.20g of c. the total number of atoms in the mixture is:  2.106× 10^23.

How to find the Total number of atoms ?

First step is to convert it into number of atoms

Atoms  of Fe = 0.250 mol × 6.02 × 10^23 /1 mol

Atoms of Fe = 1.505 ×10^23

1.20g of C to atoms of C

Molar mass of C =12.011g/mol

Atom of C = 1.20g × 1 mol/12.011g × 6.02 × 10^23 /1 mol

Atom of C = 6.014× 10^22

Now let find the total number of atoms

Total number of atoms  = Atoms of Fe + Atoms of C

Total number of atoms  =  1.505 ×10^23 + 6.014× 10^22

Total number of atoms   = 2.106× 10^23

Therefore the Total number of atoms  is  2.106× 10^23

California, a city that is far inland, such as Sacramento, is typically warmer than a city near the coast, such as San Francisco agree or disagree

Answers

Answer:

correct

Explanation:

I agree that California cities that are farther inland, such as Sacramento, are typically warmer than those that are near the coast, such as San Francisco. This is because the coast has a cooling effect due to the ocean breeze and the proximity to the ocean, which helps to moderate temperatures. Inland areas, on the other hand, are farther from these cooling influences and can experience higher temperatures, especially during the summer months

Knowing how atoms and molecules behave in chemical reactions in chemistry depends on understanding electron transfer processes. The transfer of one or more electrons from one species.

to another occurs in electron transfer reactions, which are closely connected to oxidation-reduction (redox) processes. Atoms' oxidation states change during redox reactions, which are chemical processes. In the process of oxidation, electrons are lost, whereas in the process of reduction, electrons are gained. In a redox reaction, an oxidizing species (the reducing agent) transfers electrons to a species that is being reduced (the oxidizing agent). The term "oxidized" refers to a species that is losing electrons, whereas the term "reduced" refers to a species that is gaining electrons.Several biological activities, including cellular respiration, photosynthesis, and biochemical reactions, depend heavily on electron transfer reactions. They are utilized in a variety of technologies, including electrochemistry, fuel cells, and batteries.

3. How many atoms of oxygen are present in 50g of Fe(H20)2(S04)3? Please answer fast

Answers

0.12  atoms of oxygen are present in 0. 04 mole NaNO3, 2. 0.097 moles of nitrogen atoms are present in 10. 5g of N2O5, 3. 0.127 atoms of oxygen are present in 50g of Fe(H20)2(S04)3

To find the number of atoms of oxygen present in 0.04 mole NaNO3, you can use the mole ratio from the chemical formula. The formula for NaNO3 is NaNO3, which means that for every 1 mole of NaNO3, there are 3 moles of oxygen atoms. Therefore, 0.04 mole of NaNO3 contains 0.04 mole x 3 atoms/mole = 0.12 atoms of oxygen.

To find the number of moles of nitrogen atoms present in 10.5 g of N2O5, you can use the molar mass and the molar ratio from the chemical formula. The molar mass of N2O5 is 108 g/mol, and the formula for N2O5 is N2O5, which means that for every 1 mole of N2O5, there are 2 moles of nitrogen atoms. Therefore, 10.5 g of N2O5 contains 10.5 g / 108 g/mol = 0.097 moles of nitrogen atoms.

To find the number of atoms of oxygen present in 50 g of Fe(H2O)2(SO4)3, you can use the molar mass and the molar ratio from the chemical formula. The molar mass of Fe(H2O)2(SO4)3 is 392.18 g/mol, and the formula for Fe(H2O)2(SO4)3 is Fe2(SO4)3.6H2O, which means that for every 1 mole of Fe(H2O)2(SO4)3, there are 6 moles of oxygen atoms.

The average speed of the car would be:

What is the average speed?

The average speed of a moving object is the ratio of the total distance traveled by the object and the total time taken to cover the distance traveled.

The average speed can be mathematically expressed as:

Average speed = total distance/total time

From the graph, the total distance traveled by the car can be estimated as:

4800 + 320 = 5120 m

Total time = 10 minutes

Average speed of the car = 5120/10 = 512 meters per minute

5120 meters = 5120/1000 = 5.12 kilometers

10 minutes = 10/60 = 0.17 hour

Average speed of the car in kilometers per hour = 5.12/0.17 = 30.12 km/h

To make up 1 L of a 0.5 M solution of EDTA starting with the free acid, the pH must be adjusted to 7.0. EDTA is a weak acid with a pKa of 2.0, 2.67, 6.16, and 10.26 for the four acetic acid groups.

At a pH of 7.0, EDTA will exist in a buffered state, meaning that it will be partially protonated and partially deprotonated.

To adjust the pH of the EDTA solution to 7.0, an alkali solution such as 10 M NaOH must be added. The amount of NaOH required can be calculated using the Henderson-Hasselbalch equation:

pH = pK a + log([base]/[acid])

where [base] is the concentration of the deprotonated form of EDTA and [acid] is the concentration of the protonated form of EDTA.

At a pH of 7.0, the acid-base equilibrium of EDTA will be:

please help

Answers

To neutralize 0.0350L of an unidentified Sn(OH)2 solution, 0.125L of a 0.075 M HBr solution is utilized. The molarity of the unknown Sn(OH)2 solution is 0.268 M.

The neutralization reaction between HBr and Sn(OH)2 is as follows:

HBr + Sn(OH)2 ---> SnBr2 + 2H2O

We can use the balanced equation and the stoichiometry of the reaction to find the molarity of the unknown Sn(OH)2 solution.

From the balanced equation, we can see that for every 1 mole of HBr, 1 mole of Sn(OH)2 is consumed.

We know that the HBr solution is 0.125L and 0.075M, so the number of moles of HBr is 0.125L x 0.075M = 0.00937 moles.

Since the number of moles of HBr is equal to the number of moles of Sn(OH)2, we can use the same number of moles to find the molarity of the unknown Sn(OH)2 solution.

The quantity of solute molecules per liter of solution is known as a solution's molarity. Therefore,

Molarity of unknown Sn(OH)2 solution = moles of solute / liters of solution

Molarity = 0.00937moles / 0.0350L = 0.268 M

Therefore, the molarity of the unknown Sn(OH)2 solution is 0.268 M.
