7 0

Answer:

mass PbI₂ formed = 1383 grams

Explanation:

Pb(NO₃)₂ + 2NaI => 2NaNO₃ + PbI₂(s)

6 mol NaI =>  1/2(6 mol) PbI₂ = 3 mol PbI₂ x 461.01 g/mol = 1383.03 grams ≅ 1383 grams (4 sig. figs.)

Furan and maleimide undergo the Diels-Alder reaction at 25 °C to give the endo product. When the reaction takes place at 90 °C,
mafiozo [28]

Answer:see attached image

Explanation:

In organic chemistry, a product may be kinetically or thermodynamically favoured. A kinetically favours product forms faster, it may not necessarily be the more stable product. The thermodynamically favoured product forms at a slower rate but is more stable. Often times, the kinetically favoured product rearranges itself to form the thermodynamically favoured product at equilibrium. The endo product of the Diels Alder reaction mentioned in the question is first formed (kinetically favoured) but rearranges to form the exo product (thermodynamically favoured) at equilibrium. This is clear shown in the reaction mechanism attached below.

Mercury can be obtained by reacting mercury(II) sulfide with
givi [52]

Answer:

111.68 g

Explanation:

Given data:

Mass of HgS needed = ?

Mass of CaS produced = 26.0 g

Solution:

Chemical equation;

4HgS + 4CaO  →     4Hg + 3CaS + CaSO₄

Number of moles of CaS:

Number of moles = mass/molar mass

Number of moles = 26 g/ 72.143 g/mol

Number of moles = 0.36 mol

Now we will compare the moles of HgS with CaS.

                 CaS             :             HgS

                   3                :               4

                   0.36           :              4/3×0.36 = 0.48 mol

Mass of HgS:

Mass = number of moles × molar mass

Mass = 0.48 mol × 232.66 g/mol

Mass = 111.68 g
