Are The Reactions Of Ordinary Molecular Hydrogen Slow Or Rapid ? Why ?

Chemistry
1 answer:
olchik [2.2K]3 years ago
4 0
In nature reactions of ordinary molecular hydrogen are slow since it's  a diatomic molecule whose atoms are held together by very strong covalent bonds.The reaction rate of hydrogen varies depending on temperature and the properties of the reactants, for instance under high temperatures above 500°C hydrogen reacts vigorously and with fluorine it reacts explosively even under low temperatures

If a molecule has an empirical formula of C2H2O and a molecular mass of 84.0 g/mol, what is the molecular formula?
lord [1]

Answer:

=C₄H₄O₂

Explanation:

Given the empirical formula of a molecule, the he the quotient of the molecular mas and and the empirical mass=constant.

84.0 g/mol/mass of(C₂H₂O)=constant

=84/(12×2+1×2×16)

=84/42

=2

Therefore, the molecular formula is (C₂H₂O)₂=C₄H₄O₂

How did knowing the number of valence electrons in one
Orlov [11]

Explanation:

Knowing the number of valence electrons in one of the alien elements helps in identifying it because the number of valence electrons can help categorize the alien element. Similar elements have the same valence electrons and knowing the category of the element can help further analyze the element.

If you have a pH of 3.35, what is the hydrogen ion concentration of the solution?
melamori03 [73]

Answer: 4.46 x 10^-4M

Explanation:

The pH of a solution is the concentration of hydrogen ion concentration in the solution. Mathematically, it is expressed as pH = -log(H+), where H+ is the concentration of hydrogen ion

On the pH scale, readings are from 1 to 14.

- pH values less than 7 are regarded as acidic. So, the solution with pH 3.35 is said to be acidic, and will produce hydrogen ions.

3.35 = -log(H+)

(H+) = Antilog (-3.35)

(H+) = 0.000446M

Place (H+) in standard form

(H+) = 4.46 x 10^-4M

Thus, the concentration of hydrogen ion in the solution with pH 3.35 is 4.46 x 10^-4M
