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.

Propose a mechanism to account for the formation of a cyclic acetal from 4-hydroxypentanal and one equivalent of methanol. If th
timofeeve [1]

Answer:

If carbonyl oxygen of 4-hydroxypentanal is enriched with O^{18}, then the oxygen label appears in the water .

Explanation:

  • In the first step, -OH group at C-4 gives intramolecular nucleophilic addition reaction at carbonyl center to produce a cyclic hemiacetal.
  • Then, one equivalent of methanol gives nucleophilic substitiution reaction by substituting -OH group in cyclic hemiacetal to produce cyclic acetal.
  • If carbonyl oxygen of 4-hydroxypentanal is enriched with O^{18}, then the oxygen label appears in the water produced at the end of reaction.
  • Full reaction mechanism has been shown below.

Identify the power of ten that defines each of these prefixes. Input your answers as 10 x where x is the power of ten. nano- ___
Gemiola [76]

<u>Answer:</u> The quantity of every prefix is written below as a power of ten.

<u>Explanation:</u>

In the metric system of measurement, the name of multiples and subdivision of any unit is done by combining the name of the unit with the prefixes.

<u>For Example:</u> deka, hecto and kilo means 10, 100 and 1000 respectively. Deci, centi and milli means one-tenth, one-hundredth, and one-thousandth respectively.

The quantity of these prefixes are written as the power of 10.

For the given prefixes:

<u>Nano:</u>  The quantity will be 10^{-9}

<u>Kilo:</u>  The quantity will be 10^3

<u>Centi:</u>  The quantity will be 10^{-2}

<u>Micro:</u>  The quantity will be 10^{-6}

<u>Milli:</u>  The quantity will be 10^{-3}

<u>Mega:</u>  The quantity will be 10^6

Hence, the quantity of every prefix is written above as a power of ten.
