The reaction below demonstrates which characteristic of a base?

svlad2 [7]

Answer: option D. the ability of a base to react with a soluble metal salt.

Justification:

NaOH is a strong base, which means that in water it will dissociate according to this reaction:

NaOH(aq) → Na⁺ (aq) + OH⁻ (aq)

On the other hand, CuSO₄ is a soluble ionic salt which in water will dissociate into its ions according to this other reaction:

CuSO₄(aq) → Cu²⁺ + SO₄²⁻

Hence, in solution, the sodium ion (Na⁺) will react with the metal salt in a double replacement reaction, where the highly reactive sodium ion (Na⁺) will substitute the Cu²⁺ in the CuSO₄ to form the sodium sulfate salt, Na₂SO₄ (water soluble), and the copper(II) hydroxide, Cu(OH)₂ (insoluble).

That is what the given reaction represents:

CuSO₄ (aq) + 2NaOH(aq) → Cu(OH)₂(s) + Na₂SO₄(aq)

Part d based on your answer to part c, how many bonding electrons and lone pair electrons (nonbonding electrons) are there in th

elena55 [62]

The Lewis Structure of HCN is shown below,

Number of Bonding Electrons:
In HCN Hydrogen is bonded to Carbon through single bond and Nitrogen is bonded to Carbon through Triple Bond. Single bond is formed by two bonding electrons, while, triple bond is formed by six bonding electrons, Hence,

Number of Bonding Electrons = 8

Number of Non-Bonding Electrons:
In HCN there is only one lone pair of electron present on Nitrogen atom which is not taking part in bonding. Hence,
Number of Non-Bonding Electrons = 2

Result:

Number of Bonding Electrons = 8

Number of Non-Bonding Electrons = 2

How many grams of sodium chloride are present in a 0.75 M solution with a volume of 500.0 milliliters?

saveliy_v [14]

The molarity of a solution is a type of expression of concentration equal to the number of moles solute per liter solution. In this problem, we are given the molarity equal to 0.75 M and a volume equal to 500 milliliters. <span>500 milliliters is equal to 0.5 liters. we multiply M and L to get the number of moles then multiply by the molar mass of NaCl. The answer is 21.92 grams.</span>
