suppose we have two reactions, a⟶b and b⟶c. you can isolate b, and it is stable.

Answers

Answer 1

To solve such this we must know the concept of chemical reaction. Therefore, b is not transition state as Transition state is not stable in a reaction.

What is chemical reaction?

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.

For b can be isolated or not, we must know whether b is transition state or intermediate by drawing energy level diagram. Intermediate can be isolated and it is stable. Transition state is not stable and hence can not be isolated.

Therefore, B is not transition state.

C Volume --> Mass --> Moles
D Moles --> Mass --> Volume

Answers

Answer: 1. 20.0 grams

2. 0.272 moles

3. B) Mass --> Moles --> Volume

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

To calculate the number of moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given molecules}}{\text{Avogadros number}}[/tex] or

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex] or  

Putting in the values we get:

1. [tex]\text{Number of moles of} Cl_2=\frac{1.7\times 10^{23}}{6.023\times 10^{23}}=0.282moles[/tex]

Mass of [tex]Cl_2=moles\times {\text {Molar mass}}=0.282mol\times 71g/mol=20.0g[/tex]

2. [tex]\text{Number of moles of NaCl}=\frac{3.28\times 10^{23}}{2\times 6.023\times 10^{23}}=0.272moles[/tex]

3. [tex]\text{Number of moles of water}=\frac{26g}{18g/mol}=1.44moles[/tex]

Volume of water =[tex]moles\times {\text {Molar volume}}=1.44mol\times 22.4L/mol=32.4L[/tex]

2 . how many moles are present in a 12.65g of potassium(k)?​

Answers

Answer:

0.324 mol

Explanation:

Mass of one mole or atomic mass of potassium is 39 g. Thus, number of moles in 12.65 g of potassium is 0.32 moles.

What is atomic mass?

Atomic mass of an element is the mass of one mole of that element. One mole of an element contains 6.022 × 10²³ atoms. This  number is called Avogadro number.

Potassium is 19th element n periodic table. It is an alkali metal in the first group. The atomic mass of potassium is 39 g/mol. This is the mass of one mole of potassium. The chemical symbol of potassium is K.

Given  mass of potassium = 12.65 g

atomic mass = 39 g/mol

number of moles in 12.65 g = mass/ atomic mass

no.of moles  = 12.65 /39 = 0.32 moles.

Therefore, the number of moles of 12.65 g of potassium is 0.32 moles.

If aluminum nitrate reacts with calcium phosphite, what is the balanced coefficient of aluminum nitrate?

Answers

Answer:

The coefficient of aluminum nitrate is 2.

Explanation:

The reaction between aluminum nitrate and calcium phosphite is:

Al(NO₃)₃ + CaHPO₃ → Al₂(HPO₃)₃ + Ca(NO₃)₂  

Now, we need to balance the equation. Let's begin with phosphite anion. On the reactant side we have 1 molecule of the anion, and on the products side we have 3 of it, so we need to add a coefficient of 3 before CaHPO₃:

Al(NO₃)₃ + 3CaHPO₃ → Al₂(HPO₃)₃ + Ca(NO₃)₂

The number of Ca atoms on the reactants side is now 3 and on the products side is 1, so we need to add a coefficient of 3 as follows:

Al(NO₃)₃ + 3CaHPO₃ → Al₂(HPO₃)₃ + 3Ca(NO₃)₂  

The reactants side has 1 atom of Al, and the products side has 2. Let's add a coefficient of 2 on the reactant side:

2Al(NO₃)₃ + 3CaHPO₃ → Al₂(HPO₃)₃ + 3Ca(NO₃)₂  

Finally, the nitrate anion has 6 molecules on the reactant side, which is equal to the number of molecules of NO₃⁻ on the product side.

Hence, in the balanced equation, we have a coefficient of 2 in aluminum nitrate.

_____________Makes the particles of the solvent and the solute move around more and come in contact more often. More contact, more opportunity for dissolving.

Answers

Answer:

Solvation

Explanation:

Solvation is the name of the process in which the particles of the solute are surrounded by the particles of the solvent molecules and they together mix together to form a solution.

In order words, it is a process of the surrounding solute particles with the solvent particles in order to form a solutions. When the water is the solvent, the process is known as hydration.  

It only occurs when the particles of the solvent and solute are in contact with each other and the opportunity for the dissolving process is more when more is the contact between the particles.

Calculate the value of Key in the following reaction if the equilibrium concentrations are
[H2S] -0.25 M, (H2) - 0.88 M, [S2] -0.44M.
2 H2Sig) = 2 H2(g) + S218)

Answers

Answer:

The value of the equilibrium constant Kc is 5.45

Explanation:

The "Law of Mass Action" states:

"For a reversible reaction in chemical equilibrium at a given temperature, it is true that the product of the concentrations of the products raised to the stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients is a constant."

This constant was called the equilibrium constant. For a reaction:

aA + bB ⇄ cC + dD

the equilibrium constant Kc is:

[tex]Kc=\frac{[C]^{c} *[D]^{d} }{[A]^{a} *[B]^{b} }[/tex]

In this case, the balanced reaction is:

2 H₂S → 2 H₂ + S₂

So, the equilibrium constant Kc is:

[tex]Kc=\frac{[H_{2} ]^{2} *[S_{2} ] }{[H_{2} S]^{2} }[/tex]

The equilibrium concentrations are

[H₂S] =0.25 M[H₂]= 0.88 M[S₂]= 0.44M

Replacing in the definition of equilibrium constant:

[tex]Kc=\frac{(0.88 M)^{2} *0.44 M }{(0.25 M)^{2} }[/tex]

Solving:

Kc= 5.45

The value of the equilibrium constant Kc is 5.45

An ionic bond, where one atom essentially donates an electron to another, forms when one atom becomes stable by losing its outer electrons and the other atoms become stable (usually by filling its valence shell) by gaining the electrons.

True/False: Energy can’t be created or destroyed: it can only be transferred from one place to another.

Answers

Answer:

true

Explanation:

Answer:

True.

Explanation:

It is true that energy cannot be made or lost, but it can move. For example, if you touch a metal pole and get a static shock, then the energy from the pole is being transferred to you. However, energy was not made or lost in the process. So, energy cannot be made or destroyed, but it can be moved. This also means there was the same amount of energy in the universe as there was millions of years ago. Hope this helps!
