What is the balanced equations for:
.Calcium and ethanol
.Potassium dichromate, Dilute Sulphuric Acid and Ethanol
.Ethanol abd oxygen
Huh? Lol.
Calcium and ethanol?
Ca --> CH3CH2OH????
???
To find the balanced equations for these chemical reactions, we need to consider the chemical formulas and the reaction conditions. Let's go through each of them:
1. Calcium and Ethanol:
Calcium (Ca) reacts with ethanol (C2H5OH) to form calcium ethoxide (Ca(C2H5O)2) and hydrogen gas (H2):
The balanced equation is:
2Ca + C2H5OH → Ca(C2H5O)2 + H2
2. Potassium Dichromate, Dilute Sulphuric Acid, and Ethanol:
Potassium dichromate (K2Cr2O7) reacts with dilute sulphuric acid (H2SO4) and ethanol (C2H5OH) to form chromium (III) sulfate (Cr2(SO4)3), potassium sulfate (K2SO4), carbon dioxide (CO2), and water (H2O):
The balanced equation is:
3K2Cr2O7 + 8H2SO4 + 6C2H5OH → 2Cr2(SO4)3 + 3K2SO4 + 6CO2 + 13H2O
3. Ethanol and Oxygen:
Ethanol (C2H5OH) reacts with oxygen (O2) to form carbon dioxide (CO2) and water (H2O):
The balanced equation is:
C2H5OH + 3O2 → 2CO2 + 3H2O
To balance these equations, you need to ensure that the number of atoms on both sides of the equation is equal. Make sure to double-check the coefficients to confirm the balanced equation.
