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.

When a cell is in a solution where the concentration of solute is the same in the cell as in the solution, the solution is calle
Elodia [21]
The answer to this question would be: isotonic

An isotonic solution has a same tonicity/concentration to the cell. This kind of solution will not cause osmosis to occur so it wouldn't shrink or swell the cells. This is why an isotonic solution is safer for the cells. The normal saline solution is isotonic to human cells and used frequently in medicine to replace body fluid.

How many neutrons are in the nucleus of an atom that has an atomic mass of 36 and an atomic number of 25?
elixir [45]

Answer:

Neutrons = 11

Explanation:

To get the number of neurons an element has you have to subtract the number of protons from the atomic mass of that element.

The number of protons is equal to the atomic number of that element.

Atomic number = Number of Protons

So the number of protons is 25

Neutrons = Atomic mass - Number of Protons

Neutrons = 36 - 25

Neutrons = 11
