Answer:
We need 0.375 mol of CH3OH to prepare the solution
Explanation:
For the problem they give us the following data:
Solution concentration 0,75 M
Mass of Solvent is 0,5Kg
knowing that the density of water is 1g / mL, we find the volume of water:

Now, find moles of
are needed using the molarity equation:
therefore the solution is prepared using 0.5 L of H2O and 0.375 moles of CH3OH, resulting in a concentration of 0,75M
<span>Dmitri Mendeleev published first the periodic. He didn't "discover" any elements but predicted where some would be on his table. These included Gallium and Germanium.</span>
Answer:
Without a calculator, there are many means to convert Celsius to Fahrenheit. Multiply the Celsius temperature by 1.8 and add 32 to get the Fahrenheit conversion With this method you get the exact temperature conversion degree.
Explanation:
Answer:
Substance with a nonpolar covalent bonds is
.
Explanation:
Polar covalent compound: This compound is formed when difference in electronegativity between the atoms is present. When atoms of different elements combine, it results in the formation of polar covalent bond. For Example:
etc..
Non-polar covalent compound: This compound is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. For Example:
etc.
Substance with a nonpolar covalent bonds is
.
Free energy is the amount of energy that can do work.
Free energy is the internal energy of a system less the amount of energy that cannot perform work.
