<span>Hello @Malikjawadarshad,

"the chemistry of carbon compounds (other than simple salts such as carbonates, oxides, and carbides)." This is the Literal Definition of Organic Chemistry, So I hope it helps. What you need to do, in this case, is state this definition, and everything you have learned to make a "Personal Definition" written by you. Do you get it? I hope so, and if not, contact me! 

Thank you,

8. A 65.0 mL 0.513 mol/l solution of glucose (C6H1206) was mixed with 125.0 mL of
Inessa [10]

Answer:

The molar concentration of the final solution is 1.71 \frac{moles}{liter}

Explanation:

Molarity is a way of expressing the concentration of solutions and indicates the number of moles of solute dissolved per liter of solution.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution.:

Molarity (M)=\frac{number of moles of solute}{volume}

Molarity is expressed in units (\frac{moles}{liter}).

Then, the number of moles of solute can be calculated as:

number of moles of solute= molarity* volume

So, in this case, the final concentration can be calculated as:

Final molarity (M)=\frac{Total number of moles of solute}{Total volume}

where, being 65 mL=0.065 L, 125 mL=0.125 L and 190 mL=0.190 L (because 1000 mL= 1 L):

  • Total number of moles of solute= 0.065 L*0.513 \frac{moles}{liter} + 0.125 L*2.33 \frac{moles}{liter}= 0.033345 moles + 0.29125 moles= 0.324595 moles
  • Total volume=  65 mL + 125 mL= 190 mL= 0.190 L

Replacing:

Final molarity (M)=\frac{0.324595 moles}{0.190 L}

Final molarity ≅ 1.71 \frac{moles}{liter}

<u><em>The molar concentration of the final solution is 1.71 </em></u>\frac{moles}{liter}<u><em></em></u>

Is it possible to predict physical or chemical changes? I don't really understand how to predict a change from the information m
Setler79 [48]

Explanation:

It is possible to predict a physical change or chemical change because they have very unique properties and differences.

A physical change is a change that alters the physical properties of matter especially form and state.

A chemical change is a change in which new kinds of matter is formed.

Here are some of the properties and indicators of the these change;

  • A physical change is easily reversible
  • Chemical changes are not easily reversible
  • Physical changes leads to the production of no new kind of matter.
  • Chemical change produces new kinds of matter
  • Physical change involves no change in mass
  • Chemical change involves a change in mass
  • Physical change requires little to no amount of energy
  • Chemical change requires considerable amount of energy.

Pls answer this asap
horsena [70]

Answer:

1. The enthalpy change for the backward reaction is –20 KJmol¯¹

2. The forward reaction is endothermic.

3. The activation energy for the forward reaction is +70 KJmol¯¹.

Explanation:

Considering the diagram given above, the following data were obtained:

1. The enthalpy change for the forward reaction being is +20 KJmol¯¹ and so, the enthalpy change for the backward reaction is –20 KJmol¯¹

2. The heat energy of the product is higher than that of the reactant. Therefore, the forward reaction is endothermic.

3. Activation energy is the minimum energy needed to be overcome in order for the reaction to proceed to product. It can be obtained from the energy profile diagram by considering the energy between the reactants and the peak.

For the question given above, Activation energy = 20 + 50

Activation energy = +70 KJmol¯¹
