Chemistry
1 answer:
Sedaia [141]2 years ago
3 0

Answer:

5.16 gm of SO3 formed with 2 g of S

Explanation:

Mole weight of  S in the equation = 2 * 32 = 62 gm

Mole weight os   O2  in the equation  6 * 16 =96 gm

From the BALANCED  equation   the grams of   S  to   O2  is

    62   to 96   so    2 g of  S will need  approx 3 gm of O2

            this shows that S is the limiting reactant------>

                            there will be O left over  (approx 1 gram)

SO3 mole weight produced from the equation is   2 (32)(3*16) = 160 gm

  62 gm of S produces 160 gm of SO3

   62/160 =  2 / x       x = 5.16 gm of  SO3   are formed

When dipentyl ether is treated with HI, what type of reaction occurs? both SN1 and SN2 SN2 E1 SN1 E2
masha68 [24]

Answer:

SN2

Explanation:

The first step of ether cleavage is the protonation of the ether since ROH is a better leaving group than RO-.

The second step of the reaction may proceed by either SN1 or SN2 mechanism depending on the structure of the ether. Methyl and primary ethers react with HI by SN2 mechanism while tertiary ethers react with HI by SN1 mechanism. Secondary ethers react with HI by a mixture of both mechanisms.

Dipentyl ether is a primary ether hence when treated with HI, the reaction with HI proceeds by SN2 mechanism as explained above.

What discovery led j.j Thomson to decide that atoms were not indivisible but are actually composed of smaller parts?
Setler79 [48]

Answer:

Thomson to decide that atoms were not indivisible, in reality are actually composed of smaller parts? Thomson used a scanning tunneling micrograph to capture images of atoms. Thomson used a beam of negatively charged particles. Thomson used only the experimental results of other scientists

Which compounds are classified as electrolytes and why?
djyliett [7]
<span>The correct answer is A. An electrolyte is a substance that conducts electricity in solution because the solution has ions that electricity can flow. KNO3 and H2SO4 dissociates into potassium, nitrate, hydronium and sulfate ions when in solution therefore they are considered as electrolytes.</span>

2AlCl3 --&gt; 2Al + 3Al2
Eva8 [605]

Answer:

1597,5 gm AlCl3 decomposed

Explanation:

2AlCl3 --> 2Al + 3Al2 If you produce 15 moles of Al, how many grams of AlCl3 decomposed? ​

FIRST, you need to write down the the correct reaction.  Your equation makes no sense

here is the correct question

2AlCl3 --> 2Al + 3Cl2    If you produce 15 moles of Al, how many grams of AlCl3 decomposed?

for every mole of Al produced, we decomposed a mole of ​AlCl3

so we produced 15 moles of Al, so we decomposed 15 moles of AlCl3

15 moles are 15 X 106.5 = 1597,5 gm AlCl3 decomposed
