Whymilk is taken as mixture​

Answers

Answer 1

Explanation:

Main compounds of milk are lactose and casein. And it is also called a colloidal mixture (i.e. in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance). Therefore milk is regarded as a mixture not as a pure substance. So this is the required answer.

Based on their definitions, electron affinity could be considered the opposite of

Answers

Based on their definitions, electron affinity could be considered the opposite of electron affinity. This is the force required to remove an electron from an atom while it is gaseous, or the propensity of an atom to lose electrons.

What is meant by electron?

The electron is a subatomic particle with a negative one elementary charge electric charge. Due to their lack of components or substructure, electrons, which are part of the lepton particle family's first generation, are typically regarded to be elementary particles.

An electron is a negatively charged subatomic particle that can exist either free or bound to an atom (not bound). Along with protons and neutrons, electrons are one of the three primary types of particles that make up an atom. Together, protons, neutrons, and electrons make up the atom's nucleus.

This is the force required to remove an electron from an atom while it is gaseous, or the propensity of an atom to lose electrons. Conceptually, this is the polar opposite of electron affinity.

Explanation:

Sulphuric acid (H2SO4) is titrated against 25.00cm3 of 0.200 mol/dm3 Sodium hydroxide solution (NaOH). It is found that 23.20 cm3 of sulphuric acid is required for neutralization. Calculate the concentration of Sulphuric acid

Answers

My answer,
Approximately 0.108 mol dm^-3

Explanations,
1. Make the balance chemical equation
2. Convert the 25 cm^3 to 0.025 dm^3 by multiplying 25 with 10^-3 (or 25 / 1000)
3. Concentration is equal to = moles of substance over volume of solution
4. Calculate how many number of moles present in 0.025dm^3 of sulphuric acid.

Mole = concentration x volume
^ rearranged from conc = mole/volume

Mole = 0.200 x 0.025 = 0.005 mol

5. Use the balance chemical equation ad mole ratio. In this case,

H2SO4 + 2NaOH —> 2H2O + Na2(SO4)

Thus the ratio between Sulphuric acid and Sodium Hydroxide is 1:2

Hence, the mole of H2SO4 is 0.005/2 = 0.0025 mol

6. Calculate the concentration of the sulphuric acid by using conc. = mole/volume

Hence the answer is 0.0025/(23.20 x 10^-3) = 0.108 mol dm^-3 rounded off at the 3 Sigfigs

Which of the following correctly completes the statement?
Cations are always _____ than the parent atom and anions are always _____ than the parent atom.

Answers

Answer: smaller, larger

Explanation:

Cations are always {smaller} than the parent atom. Anions are always {larger} than the parent atom.

Cations are always smaller than the parent atom, and anions are always greater than the parent atom.

What is parent atom ?

The term "parent atom" refers to an atom that has not yet undergone any chemical transformation. A parent atom is one that is discovered in its initial state.

Because they contain fewer electrons while maintaining the same nuclear charge, cations are always smaller than their parent atoms. Because the protons in the nucleus are holding the remaining electrons more tightly, their radii are less than those of the parent atoms. In the case of anion, this is the opposite.

Due to variations in electron-electron repulsion, the ionic radii of cations and anions are always less or bigger than the parent atom, respectively. The trends in ionic radius follow those in atomic size.

Thus, Cations are always smaller than the parent atom, and anions are always greater than the parent atom.

Answers

Answer:

2CHCl3 + 5/2 O2 => 2CO2 + H20 + 3Cl2

Explanation:

Left Hand Side(LHS)

We have CHCl3 and O2

Right Hand Side(RHS)

We have CO2, H2O and Cl2

Balancing

To make sure that they have same values, put 2 before CHCl3 giving 2CHCl3 and 3 on Cl2(RHS) for chlorine gas giving 3Cl2

H2O remains the same

Before CO2 put 2 giving 2CO2

To make sure that oxygen is balanced put 5/2 before it. This gives 5/2 O2 (2 cancels out don't worry)

Combining all;

2CHCl3 + 5/2 O2 => 2CO2 + H20 + 3Cl2

I hope this helps. Have a nice studies.

2.00 L

Answers

A 3.00-L container with O₂ at 4.00 atm is connected to a 2.00-L container with Ne at 2.00 atm, resulting in a final pressure of 3.20 atm in the container.

We have 2 containers connected by a valve.

One container has a volume of 3.00 L and contains O₂ at 4.00 atm. The other container has a volume of 2.00 L and contains Ne at 2.00 atm.

When the valve is opened, the total volume is the sum of the 2 containers.

[tex]V_2 = 3.00 L + 2.00 L = 5.00 L[/tex]

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

O₂

[tex]P_1 \times V_1 = P_2 \times V_2\\\\P_2 = \frac{P_1 \times V_1}{V_2} = \frac{4.00atm \times 3.00L}{5.00L} = 2.40atm[/tex]

Ne

[tex]P_1 \times V_1 = P_2 \times V_2\\\\P_2 = \frac{P_1 \times V_1}{V_2} = \frac{2.00atm \times 2.00L}{5.00L} = 0.800atm[/tex]

The final pressure in the container will be the sum of the final pressures of the gases.

[tex]P = 2.40 atm + 0.800 atm = 3.20 atm[/tex]

Kinda confused on this. i need some help.​

Answers

Balancing chemical equations is like a small puzzle. The ultimate goal is to end up with the same number of atoms on both sides of the arrow.

To start, check to make sure it isn’t already balanced. If coefficients aren’t present, it’s assumed to be one. In this case, there’s just one aluminum on both sides, but the right hand side has one more fluorine than the left. This means that we’ll have to change the coefficients to make them match. Since we can’t multiply the two fluorines to make three with a whole number, we have to change this one and the one in front of the aluminum fluoride. Let’s put a 3 in front of F2 and a 2 in front of AlF3. So far, we have:

Al + 3F2 -> 2AlF3

Check the number of fluorines; sure enough, we have six on both sides. However, we’ve imbalanced the aluminums by balancing the fluorines. The fix is easy, though; change the coefficient from one to two in front of the aluminum to make them match. The result is therefore:

2Al + 3F2 -> 2AlF3

Check your element totals again; sure enough, they’re all balanced. This is the balanced chemical equation.
