The partial pressure of carbon dioxide in the atmosphere is 0.239 torr. Calculate the partial pressure in mm Hg and cant Round e
victus00 [196]

Explanation:

It is known that 1 torr equals 1 mm Hg.

Therefore, 0.239 torr will be converted into mm Hg as follows.

                     1 torr = 1 mm Hg

So,          0.239 torr = 0.239 torr \times \frac{1 mm Hg}{1 torr}

                                 = 0.239 mm Hg

It means that 0.239 torr is equal to 0.239 mm Hg.

Therefore, we can conclude that partial pressure of given carbon dioxide in mm Hg is 0.239 mm Hg.

Not all solutions are solids dissolved in liquids. Provide 2 examples of other types of solutions.
kiruha [24]
<span>A substance only dissolves if the attraction between the particles of the solute and the solvent is enough to overcome the attraction of the particles of each substance for others of the same type. For instance, the attraction between the ions in table salt and water molecules is enough to both pull individual ions away from the salt crystal and to separate the water molecules to accommodate the ions. Benzene, on the other hand, does not attract the ions of salt strongly enough to remove them from the crystals. Napthalene does not dissolve in water because napthalene does not exert a strong enough attraction to water molecules to separate them and make room for itself.</span>

Ni(NO3)2 (aq) + 2NaCl (aq)------&gt;________________________ + ________________________
Alex787 [66]

Explanation:

Nickel(II) nitrate = Ni(NO3)2

Sodium Chloride = 2NaCl

Sodium Nitrate = 2NaNO3

Nickel(II) Chloride = NiCl2

Balanced equation :

Ni(NO3)2 + 2NaCl → 2NaNO3 + NiCl2

Complete Ionic equation:

Ni2+(aq) + 2NO3-(aq) + 2Na+(aq) + 2Cl-(aq) = 2Na+(aq) + 2NO3-(aq) + Ni2+(aq) + 2Cl-(aq)

Net ionic equation:

The balanced net ionic equation includes only species that are involved in the reaction. It can be found by removing ions that occur on both the reactant and product side of the complete ionic equation.

All the ions are spectator ions so there is no reaction.
