Answer:
Explanation:
Hello,
In this case, the unit of concentration is molality which is defined by:
Whereas the mass of the solvent is measured in kilograms. In such a way, with the given data, we first compute the kilograms of water:
Then, we solve for the moles of the solute:
Finally since the molar mass of ethanol is 46 g/mol, we compute the grams for the given solution:
Best regards.
Answer:
The halogens form acidic compounds with hydrogen. The halogens are the most reactive among all the nonmetals
Hello!
On the periodic table, as we go down the periodic table, the ionization energy decreases, but as we go across the periodic table (left to right), the ionization increases.
On the periodic table, lithium (Li) is located in column one, beryllium (Be) is located in column two, and (B) boron is located in column 13. As stated above, when we go across the periodic table (left to right), the ionization increases.
Therefore, the element with the highest ionization energy is Boron, or symbol B on the period table.
