Answer:
Explanation:
C₂H₂ + 2H₂ = C₂H₆
1 mole 2 mole 1 mole
Feed of reactant is 1.6 mole H₂ / mole C₂H₂
or 1.6 mole of H₂ for 1 mole of C₂H₂
required ratio as per chemical reaction written above
2 mole of H₂ for 1 mole of C₂H₂
So H₂ is in short supply . Hence it is limiting reagent .
1.6 mole of H₂ will react with half of 1.6 mole or .8 mole of C₂H₂ to form .8 mole of C₂H₆
a )Calculate the stoichiometric reactant ratio = mole H₂ reacted/mole C₂H₂ reacted
= 1.6 / .8 = 2 .
b )
yield ratio = mole C₂H₆ formed / mole H₂ reacted ) = 0.8 / 1.6 = 1/2 = 0.5 .
Emperic formula is SO subscript 2. Molecular formula would be SO subscript 2 multiply 1 so it's the same answer.
Answer:
it's the uneven heating of the region's of the troposphere by the sun the sun warms the air at the equator more than the air at the poles. it causes convention currents large scale patterns of winds that move heat and moisture around the globe. as air rises expands and cools water vapor condenses and clouds develop.
Explanation:
I hope this helps :)
The error is in the formula is bracket so the correct is Mg(OH)₂
The incorrect or error in the formula is bracket that would be that the compound contain only 1Mg atom and 1 oxygen atom and 2 hydrogen atom but is wrong when you write it in an electron dot diagram you will see that it is wrong there be unshared paired of electron and the correct formula is Mg(OH)₂

To find molarity
We need no.of moles and solution in liter
Given data is in grams and ml
We have to convert it in required units
For no.of moles use formula
No.of mole=mass in gram / molar mass
Mass in gram = 29.1g
Molar mass = 160.4374g/mol calculated by adding the atomic wight of all atoms in LiClO4.3H2O
Atomic weight
Li= 6.941
Cl= 35.453
O= 15.9994
H= 1.00794
Now put it in mol equation
No.of mole = 29.1/160.4374
= 0.181mol of solute
Now convert solution in L from ml
235ml = 235/1000 = 0.235L
Now put these values in molarity formula
Molarity= 0.181/0.235
= 0.77M solution
