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.
