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

a) Diamond can indeed be set on fire since it is made of carbon. ... Although diamond requires a higher temperature to burn, it does indeed burn via normal carbon combustion. You can even burn diamond in a regular flame if you are patient and conditions are right.

b) In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut.

c) Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.

An atom's Lewis dot structure has three dots. Which of the following elements could it be, and why? (4 points)

Group of answer choices

Aluminum, because it is in group 13 and has three valence electrons.

Lithium, because it is a group 1 element with three total electrons.

Magnesium, because it is in period 3 and has three valence electrons.

Potassium, because it is an alkali metal and has three inner shell electrons.

Answers

Answer : The correct option is, Magnesium because it is a group 2 element with two valence electrons.

Explanation :

Element = Calcium

Atomic number = 20

Electronic configuration of Ca =  

Number of valence electrons in Ca = 2

The number of inner shell electrons in Ca = 18

This option is wrong because lewis-dot structure shows only valence electrons not inner shell electrons.

Element = Carbon

Atomic number = 6

Electronic configuration of C =  

Number of valence electrons in C = 4

This option is wrong because only outermost p-sublevel electrons are not showing in lewis-dot structure.

Element = Lithium

Atomic number = 3

Electronic configuration of Li =  

Number of valence electrons in Li = 1

This option is wrong because it has only 1 electron in outermost shell.

Element = Magnesium

Atomic number = 12

Electronic configuration of Ma =  

Number of valence electrons in Ma = 3

This option is correct.

Lewis-dot structure : It is defined as the structure in which valence electrons of the atom is shown as dots.

ANOTHER EXPLANATION:

Answer: C. Magnesium, because it is a group 2 element with two valence electrons.

An atom's Lewis dot structure has two dots. Which of the following elements could it be, and why?

A. Calcium, because it is an alkaline earth metal with two inner shell electrons.

B. Carbon, because it has two electrons in its outermost p sublevel.

C. Lithium, because it is a group 1 element with two bonding electrons.

D. Magnesium, because it is a group 2 element with two valence electrons.

Explanation:

If you were to look at the periodic table magnesium would be in group 2. Since magnesium is in group 2 therefore it will have two valence electrons. Calcium is another possible answer because it is also in group two, but for this quiz it is incorrect. Lithium is incorrect because it is in group 1 and therefore it would only have 1 valence electron. Carbon is also incorrect because it is in group 14 so it would have 4 valence electrons. Hope this helps and makes sense.

Good Luck!!

The Lewis dot structure of an atom has three dots. With three valence electrons and belonging to group 13, which of the following elements may it be?

Are the elements of group 13 metals?

The semi-metal boron (B) and the metals aluminum (Al), gallium (Ga), indium (In), and thallium (In) are all members of the boron family (Tl). The periodic table's fifth element, boron (Z=5), is found in Group 13. It is categorized as a metalloid because of its characteristics, which combine those of metals and nonmetals.

What traits does group 13 exhibit?

The Periodic Table of Elements places these elements in Group 13 (XIII) of the p block. Metallic elements include thallium, gallium, indium, and aluminum. In their outermost shells, they each have three electrons shell with the valence electron configuration ns2np1 (one electron in the p orbital and a complete s orbital).

Salt and sand can be separated by dissolving the salt in water, filtering the mixture, and then evaporating the water to recover the salt.

There is a golden role of solubility, polar solute dissolve in polar solvent and non polar solute dissolve in non polar solvent. Therefore, Salt and sand can be separated by dissolving the salt in water, filtering the mixture, and then evaporating the water to recover the salt.

What is solution?

Solutions are a homogeneous mixture of two or more substances. A solution is a homogeneous mixture of solvent and solute molecules. Solvent is a substance that is in large amount in solution.

Solute is the substance which is in small amount in a solution. Salt and sand can be separated by dissolving the salt in water, filtering the mixture, and then evaporating the water to recover the salt.

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.

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.
