Answer: 1.3 L
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
To calculate the volume for given molarity, we use the equation:
![\text{Volume of solution in L}=1.3](https://tex.z-dn.net/?f=%5Ctext%7BVolume%20of%20solution%20in%20L%7D%3D1.3)
Thus the volume in Liters is 1.3
Answer:
The rubbing of certain materials against one another can transfer negative charges, or electrons. ... Remember, objects with the same charge repel each other. Because they have the same charge, your hair will stand on end. Your hairs are simply trying to get as far away from each other as possible!
NaCl consists of a salt, which is a nonmetal (Na) and Cl, which is a metal. When a nonmetal and a metal are combined, it makes the compound ionic.
Hey there!
When two or more substances combine, they create one or more new substances, which sometimes have different molecular structures from the original substances, meaning they absorb and radiate light in different ways, leading to a color change.
Hope this helps! :)
This problem is providing us with the chemical equation for the decomposition of water to hydrogen and oxygen, the involved bond energies and asks for the total energy of the reaction as well as whether it is endothermic or exothermic. At the end, one comes to the conclusion that it is exothermic because the total energy is -425 kJ.
<h3>Bond energy:</h3>
In chemistry, bond energies are defined as the necessary energy to break a bond between two atoms. In this case, we see that water, H2O has two H-O bonds and hydrogen and oxygen have two H-H and one O=O bonds, respectively.
Thus, we write the following heat equation, which comprises the aforementioned bond energies and the stoichiometric coefficients in the reaction:
![\Delta H=2*\Delta H_{H-O}-(2*\Delta H_{H-H}+\Delta H_{O=O})](https://tex.z-dn.net/?f=%5CDelta%20H%3D2%2A%5CDelta%20H_%7BH-O%7D-%282%2A%5CDelta%20H_%7BH-H%7D%2B%5CDelta%20H_%7BO%3DO%7D%29)
Hence, we plug in the given bond energies to obtain:
![\Delta H=2*467kJ/mol-(2*432kJ/mol+495kJ/mol)\\ \\ \Delta H =-425kJ/mol](https://tex.z-dn.net/?f=%5CDelta%20H%3D2%2A467kJ%2Fmol-%282%2A432kJ%2Fmol%2B495kJ%2Fmol%29%5C%5C%0A%5C%5C%0A%5CDelta%20H%20%3D-425kJ%2Fmol)
Where the negative suggests this is an exothermic reaction as it releases energy (negative enthalpy).
