Metallic properties tend to increase in which direction on the periodic table

Predict the product(s) of the following neutralization reaction. Type the balanced the equation.

REY [17]

Answer:

The products from the neutralization reaction are barium nitrate and water.

The balanced chemical equation is

2 $HNO_{3}$ + 1 $Ba(OH)_{2}$ --> 1 $Ba(NO_3)_{2}$ + 2 $H_{2}O$ .

Arrange the following in order of increasing bond strength of the carbon oxygen bond: Group of answer choices Carbon monoxide &l

Irina-Kira [14]

Answer:

carbonate ion < carbon dioxide < carbon monoxide

Explanation:

Bond strength depends on the bond order of a bond. The higher the bond order, the greater the bond strength since shorter bonds are stronger than longer bonds.

The carbonate ion has a bond order of 1.33, carbon dioxide has a bond order of 2 while carbon monoxide has a bond order of 3.

Since the compound with the highest C-O bond order has the strongest C-O bond, then carbon monoxide possesses the strongest C-O bond.

Answer:

Most solids in solution exhibit a general trend of increasing solubility with increasing temperature.

A seed crystal may be added to a supersaturated solution to precipitate excess solute.

Explanation:

For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions(Lumen Learning).

When a seed crystal is added to a supersaturated solution, excess solute begin to precipitate because the seed crystal now furnishes the required nucleation site where the excess dissolved crystals now begin to grow.
