What is the molarity of 2 moles of a compound dissolved in 4 L of water?
A. 2 M
B. 0.5 M
C. 4M
D. 1 M

Answers

Answer:

[tex]\boxed {\boxed {\sf B. \ 0.5 \ M}}[/tex]

Explanation:

Molarity is a measure of concentration in moles per liter. The formula for calculating molarity is:

[tex]molarity= \frac{moles \ of \ solute}{ liters \ of \ solution}[/tex]

There are 2 moles of a compound or the solute. There are 4 liters of water or the solution.

moles of solute= 2 mol liters of solution = 4 L

Substitute the values into the formula.

[tex]molarity = \frac{ 2 \ mol}{ 4 \ L}[/tex]

Divide.

[tex]molarity= 0.5 \ mol /L[/tex]

1 mole per liter is equal to 1 Molar, so the solution's molarity of 0.5 mol/L is equal to 0.5 M.

[tex]molarity = 0.5 \ M[/tex]

The molarity of the solution is 0.5 Molar and choice B is correct.

I'm having trouble understanding what "the difference in energy between the products and reactants from the surroundings" means. Can you help explain what this means? please​

Answers

Answer:

The energy change in a chemical reaction is due to the difference in the amounts of stored chemical energy between the products and the reactants. This stored chemical energy, or heat content, of the system is known as its enthalpy.

Explanation:

Due to the absorption of energy when chemical bonds are broken, and the release of energy when chemical bonds are formed, chemical reactions almost always involve a change in energy between products and reactants. By the Law of Conservation of Energy, however, we know that the total energy of a system must remain unchanged, and that oftentimes a chemical reaction will absorb or release energy in the form of heat, light, or both.

why can't sodium salt be prepared by double decomposition

Answers

Normally, reacting a metal and an aqueous acid will produce a salt and hydrogen gas, as in the case of iron:

Fe(s)+2HCl(aq)⟶FeCl2(aq)+H2(g)


However, you should not use the same method to produce, for example, sodium chloride:

2Na(s)+2HCl(aq)⟶2NaCl(aq)+H2(g)

Sodium salt might not be prepared by double decomposition because the method is used in preparing insoluble salts.

What is Double decomposition method?

Double decomposition method serves as the method that is used in preparing compounds which entails reaction between two soluble compounds and after reaction soluble and insoluble products are produced.

Therefore, since most of the sodium salt are soluble salt , Double decomposition cannot be used to prepare them.

A Questic
Is the following reaction feasible at 340K? Mg + ZnO -> MgO + Zn Enthalpy Data: Mg: 0 kJ/mol ZnO: -348 kJ/mol MgO:-602
kJ/mol Zn: 0 kJ/mol Entropy Data: Mg: 33 J/K mol ZnO: 44 J/K mol MgO: 42 J/K mol Zn: 27 J/K mol
A. No, it is not feasible because the Gibbs free energy change is negative.
OB. Yes, it is feasible because the Gibbs free energy change is negative.
C. No, it is not feasible because the Gibbs free energy change is positive.
D. Yes, it is feasible because the Gibbs free energy change is positive.

Answers

Answer:

No, it is not feasible because the Gibbs free energy change is positive

Explanation:

∆Hreaction= (-602 KJ/mol) - (-348 KJ/mol) = -254 KJ/mol

∆Sreaction = (42 + 27) J/Kmol - (33 + 44) J/K = -8J/Kmol

From;

∆G = ∆H - T∆S

∆G = 254 × 10^3 J/mol - [340K × (-8 J/Kmol)]

∆G = 2.57 × 10^5 J/mol

Note that when the change in free energy is positive, a reaction is non spontaneous. Only a reaction that has a negative change in free energy is spontaneous.

Answer:

B. Yes, it is feasible because the Gibbs free energy change is negative.

Explanation:

the other two don't make sense

The statements C and D are correct, i.e., curly hair have different protein structure from straight hair and curly hair results from a change in the gene.

What is protein?

Proteins are biomolecules made of amino acids. Proteins are very essential to all living things and contributes the body structure. Proteins are mainly up taken through diet and they are the main source of energy.

Hair is made of keratin protein. Keratin makes up our skin and nails too.Curly hair is originating by birth not developing over time. Curly hair is more likely to be occurring through inheritance.

The protein structure the hair follicle is some more bend for curly hair. Curly hair and straight hair originates from different gene traits. The gene type is inherited from the parents.

Hence, for people with curly hair have different protein structure and it result from a change in gene that code for hair structure. Thus options C and D are correct.
