C. a measurement of the ability of an atom to attract an electron
I believe it is "They have hydroxide ions" because bases are usually made up of hydroxide ions and other element ions.
With that informatio you can:
1) Write the chemical equation
2) Balance the chemical equation
3) State the molar ratios
4) Predict if precipitation occurs.
I will do all four, for you:
1) Chemical equation:
mercury(I) nitrate potassium bromide mercury(I) bromide potassium nitrate
<span>Hg2(NO3)2 + KBr → Hg2Br2 + KNO<span>3
2) Balanced chemical equation
</span></span>
<span>Hg2(NO3)2 + 2KBr → Hg2Br2 + 2KNO<span>3
3) Molar ratios or proportions:
1 mol </span></span><span>Hg2(NO3)2 : 2 mol KBr : 1 mol Hg2Br2 : 2 mol KNO<span>3
4) Prediction of precipitation.
You can use the solubility rules or a table of solubilities. I found in a table of solutiblities that mercury(I) bromide is insoluble and potassium bromide is soluble, Then you can predict that the precipitation of mercury(I) bromide will occur.

Explanation:
Bases have a slippery feel when touched but acids do not have a slippery feel.
- An acid is a substance that interacts with water to produce excess hydroxonium ions, H₃O⁺ in an aqueous solution. Here are some of its properties:
- Their dilute solutions have a sour taste.
- They have a burning effect on the skin and are highly corrosive on metals.
- They have the ability to change the colors of indicators.
- They react with bases to form salt and water only.
Examples of acids are:
Hydrochloric acid HCl
Tetraoxosulphate (VI ) acid H₂SO₄
- A base is a substance that interacts with water to produce excess hydroxide ions, OH⁻ in an aqueous solution.
- They typically have a bitter taste.
- They have a soapy feel
- They are electrolytes
- They also change the color of indicators
Examples are:
Potassium hydroxide KOH
Sodium hydroxide NaOH
