Protons identity the element because the number of protons gives us the atomic number of each element
<span>The only scenario that
will allow you to reach an equilibrium mixture involving these chemicals is to
place NH3 into a sealed vessel. This reaction requires pressures between 2100,
3600 psi, and temperatures between 300 and 550 degree Celsius. With this given
temperature and pressure, the ammonia naturally decomposes into nitrogen and
hydrogen gas at the same rate. When this happen, the concentrations of these
chemicals become constant and the system is said to be at equilibrium.</span>
heterogeneous mixture, because, the layers are called phases and a heterogeneous mixture has two or more phases. the oil phase is less dense then water so it floats on top, etc.
Answer:
1.6mole of H2O
Explanation:
First let us generate a balanced equation for the reaction. This is illustrated below:
2H2 + O2 —> 2H2O
Molar Mass of O2 = 2 x 16 = 32g/mol.
Mass of O2 = 25.6g
Number of mole of O2 = Mass /Molar Mass
Number of mole of O2 = 25.6/32
Number of mole O2 = 0.8mol
From the equation,
1mole of O2 produced 2moles H2O.
Therefore, 0.8mol of O2 will produce = 0.8 x 2 = 1.6mole of H2O
