Reactant = 2KMnO4
Products = K2MnO4 + MnO2(s) + O2(g)
A. Oxygen turned in to carbon dioxide
Incorrect option - Oxygen is not the reactant
B. Sulphate and lithium boiled
Incorrect option - Sulphate and lithium are not part of this reaction

6. The Haber process for making ammonia (NH)
gas from its elements was developed by Fritz Haber
during WWI. Haber hoped to use ammonia as
fertilizer to grow food for Germany during the
Allie's blockade. How many liters of hydrogen
would be required to produce 40.0L of ammonia at
STP? N+H, NH,
Answers
Answer:
60 Liters
Explanation:
The equation for this reaction is given as;
N2 + 3H2 → 2NH3
From the reaction;
3 mol of H2 produces 2 mol of NH3
At STP;
1 mol = 22.4 L
This means
67.2 L ( 3 * 22.4) of H2 produces 44.8 L ( 2 * 22.4) of NH3
How many L of H2 would produce 40 L of NH3
67.2 = 44.8
x = 40
Solving for x;
x = 40 * 67.2 / 44.8
x = 60 L
Nitric monoxide (NO) reacts with oxygen gas to form nitrogen dioxide (NO₂), a dark brown gas. If 5.895 mol of NO is mixed with 2.503 mol of O₂,
determine the limiting reagent.
calculate the number of grams of NO₂ produced.
and determine how many grams of excess reagent remain unreacted.
Answers
Answer:
Limiting reactant: O2
grams NO2 produced = 230.276 g NO2
grams of NO unused = 26.67 gNO
Explanation:
2NO + O2 --> 2NO2
Step 1: Determine the molar ratio NO:O2
molar ratio NO:O2 = 5.895: 2.503 = 2.35
stoichiometric molar ratio NO:O2 = 2:1
So, O2 is the limiting reactant.
Step2: Determine the grams of NO2:
?g NO2 = moles O2 x (2moles NO2/1 mol O2) x (MM NO2/ 1 mol NO2) = 2.503 x 2 x 46 = 230.276 g NO2
Step 3: Determine the amount of excess reagent unreacted
moles excess NO reacted = moles O2 x (2 moles NO/1 mol O2) = 2.503 x 2 = 5.006 moles NO reacted
moles NO unreacted = total moles NO - moles NO reacted = 5.895-5.006 =0.889 moles NO unreacted
mass NO unreacted = moles NO unreacted x MM NO = 0.889 x 30 =26.67 g NO unreacted

How much H2O is produced when 40000 g of
C2H, burns completely?
Answer in units of g.
Answers
Answer:
1200g H20.
Explanation:
Write out the balanced equation... when an organic compound is burned, like C2H2, it is burned in oxygen (O2) and produces Water and Carbon Dioxide (CO2)
so 2C2H2 + 5O2 = 2H2O + 4CO2
now that you have a balanced equation just convert to moles and solve
2000g C2H2 * 1mol C2H2 / 30gC2H2 * 2mol H2O/2mol C2H2 * 18gH2O/1molH20 = 1200g H20.
what is the percent yield of carbon dioxide of 2.5 mole of oxygen react and 32.4 g of carbon dioxide are produced?
please help!!
Answers
Answer:
86
Explanation:
According to the concept of percent yield, the percent yield of carbon dioxide is 72.51%.
What is percent yield?Percent yield is defined as the ratio of actual yield to the theoretical yield multiplied by 100. If the actual and theoretical yield are same then the percent yield is 100%.If actual yield is less than the theoretical yield then the percent yield is less than 100%.Reason of this condition arising is the incompletion of reaction or loss of sample during recovery process.
In cases where percent yield is over 100% it indicates that more sample is recovered than the predicted amount.This condition arises when there are other simultaneous reactions taking place leading to the formation of product. It can also arise if there is incomplete removal of impurities from the sample .
In the given example, theoretical yield of carbon dioxide is as 32 g oxygen produces 44 g carbon dioxide,thus 32.5 g which is obtained by 2.5 moles of oxygen will require 32.5×44/32=44.68 g
Thus , on substitution in formula of percent yield, 32.4/44.68×100=72.51%.
Hence, the percent yield of carbon dioxide is 72.51%.

What are compounds?
Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.
Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:
1)Molecular compounds where in atoms are joined by covalent bonds.
2) ionic compounds where atoms are joined by ionic bond.
3)Inter-metallic compounds where atoms are held by metallic bonds
4) co-ordination complexes where atoms are held by co-ordinate bonds.
They have a unique chemical structure held together by chemical bonds Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.
