O2 + ch4 co2 + h2o what would be the coefficient of the diatomic oxygen molecule in the balanced reaction?
2 answers:
Answer:
<h2>The coefficient of the diatomic oxygen has to be 2.</h2>Explanation:
The balanced reaction should be like this:
So, as you can see, balance mean that molecules in the reaction has to be equal, the amount of element involved has to be the same, due to the Conservation of the Mass Law.
So, Hydrogen and Oxygen are not balanced in the given expression, that's why we need to add those coefficients.

Answer:
1.53 × 10²³ molecules As₂O₃
Explanation:
Step 1: Define
Diarsenic Trioxide - As₂O₃
Avagadro's number: 6.02 × 10²³ atoms, molecules, formula units, etc.
Step 2: Use Dimensional Analysis
= 1.52908 × 10²³ molecules As₂O₃
Step 3: Simplify
We have 3 sig figs.
1.52908 × 10²³ molecules As₂O₃ ≈ 1.53 × 10²³ molecules As₂O₃
Answer:
A central C is double bonded to an O, and single bonded to 2 H
Explanation:
Methanal, also known as formaldehyde, is a chemical compound used to preserve dead biological specimens for further study. It is called formalin when in a solution and it helps keep specimens in a fresh state by hardening the tissues of the specimen involved.
Formaldehyde is a gaseous compound that has an aldehyde functional group i.e. -CHO and has a chemical formula, H-CHO or CH2O as described in the question that a central C is double bonded to an O, and single bonded to 2 H (see attached image for structural formula).
