H2 + O2 -> 2H2O balanced or unbalanced pls help

Chemistry
1 answer:
Sidana [21]3 years ago
7 0

Answer:

Unbalanced

Explanation:

The reaction equation is given as:

             H₂  +  O₂  →   2H₂O

The given reaction flouts the law of conservation of mass and it is not balanced. To know a reaction that is balanced, the number of atoms on both sides of the expression must be the same;

                                             Number of moles

                         Reactants                                             Products

Hydrogen                2                                                            4

Oxygen                   2                                                            2

We see that the hydrogen atoms are not balanced.

Balance the following equation in acidic conditions. Phases are optional.
NISA [10]
I think the reaction involved here is a redox reaction in acidic conditions. To balance this type of reaction, we do as follows:

Balance the O atoms in each side by adding H2O on either side.
Balance H atoms in each side by adding H+.
Balance the charges by adding electrons.

Hope this helps.

Both the codons uuu and uuc specify the amino acid phenylalanine. what is the term for this phenomenon?
kaheart [24]

This is called codon degeneracy. It is also said that the genetic code is redundant, meaning that multiple codons can code for the same amino acid, like for example CCC and CCA both coding Proline.
