It is possible to dehydrate neutral and basic gases, amines, low-boiling alcohols, and ethers using calcium oxide, a basic drying agent. its chemical formula is CaO.

CaO cannot be substituted with sulfuric acid. Because the salt ammonium sulfate is created when sulphuric acid and ammonia combine, this is the case. Calcium oxide is a solid that is odorless, white, gray-white, and appears as hard lumps. powerful skin, eye, and mucous membrane irritant. used in fertilizers and pesticides. The group of calcium oxides with a 1:1 ratio of calcium to oxygen includes calcium oxide. It functions as fertilizer.

Calculate the number of moles of KOH in 6.70 mL of a 0.480 M KOH solution. (Enter your answer in scientific notation.)
andrew-mc [135]

Answer:

3.2×10^-3 mol

Explanation:

The equation for molarity is M= n/L. Where "M" is Molarity, "n" is the number of moles of solute, and "L" is the total liters in solution.

The question gives you the volume in mL, so to convert "mL" to "L" you need to divide by 1000. (6.70mL/ 1000L)= 0.0067L.

Now you can plug the numbers into the equation. 0.480M= n/ 0.0067L), multiply (0.480M×0.0067L)= 0.003216 mol. The scientific notation is 3.2×10^-3, 10^-3 because you move the decimal back three times and 3.2 because there are 2 sig figs.

Explain in terns of atomic structure why barium has a lower first ionization energy than magnesium.
Sonja [21]

Answer:

Barium has a greater radius than magnesium

Explanation:

Barium and magnesium are two elements which belong to the same group, group 2A. This means that the two elements have two valence electrons in their outer shell.

The difference is, however, since barium is lower in group than magnesium, it has more electron shells than magnesium and, therefore, its radius is greater. The attraction force between the nucleus and the valence electrons in barium is lower as a result, as force is inversely proportional to distance. Hence, a lower amount of energy is required to remove the valence electrons from barium.
