If 4.88 grams of zn react with 5.03 grams of s8 to produce 6.02 grams of zns, what are the theoretical yield and percent yield o
nataly862011 [7]
<span>Balance the equation
    8Zn + S8 -----> 8ZnS
    work out how much ZnS is possible if all of each reagent were to react. The reagent that produces the least product is the limiting reagent.
    moles Zn = mass / molar mass = 4.88 g / 65.38 g/mol = 0.07464 moles
  8 moles Zn reacts to form 8 moles ZnS
  Therefore moles ZnS possible = moles Zn = 0.07464 moles

    moles S8 = 5.03 g / 256.48 g/mol = 0.01961 mol
  1 mole S8 reacts to form 8 moles ZnS
  Therefore moles ZnS possible = 8 x moles S8 = 0.1569 mol

    The amount of Zn provided gives the least ZnS, therefore Zn is the limiting reagent.
    The theoretical yield is the maximum possible yield possible from the reagents provided. It is the amount of product that will form if all the limiting reagent reacts.
  So in this case 4.88 g Zn yields 0.07464 mol ZnS

    theoretical mass ZnS = molar mass x moles
  = 97.44 g/mol x 0.07464 mol
  = 7.27 g

    % yield = actual yield / theoretical yield x 100/1
  = 6.02 g / 7.27 g x 100/1
  = 82.8 %</span>

How many liters are there in 3.0 moles of CO2 at STP?
Lerok [7]

There are 67.2 liters of CO2 at STP

<h3>Further explanation</h3>

Given

3 mole of CO2

Required

Volume of CO2 at STP

Solution

Standard conditions for temperature and pressure are used as a reference in certain calculations or conditions

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.

So for 3 moles :

= 3 x 22.4 L

= 67.2 L

Is the genie in the bottle experiment a physical or chemical change/reaction?
gladu [14]

Answer:

Chemical reaction.

Step-by-step explanation:

In the experiment, a catalyst is added to concentrated hydrogen peroxide.

The hydrogen peroxide <em>decomposes</em> rapidly, according to the equation

2H₂O₂(ℓ) ⟶ 2H₂O(ℓ) + O₂(g)

New substances are formed, and old ones disappear, so this is a chemical reaction.

The reaction also releases a <em>large amount of heat</em>.

The rapidly-expanding oxygen gas caries with it droplets of water and hydrogen peroxide (and probably some steam, as well).

The visual effect is like a genie escaping from its bottl<em>e</em>.
