If it has a metal and a nonmetal bonded together it is an ionic bond. you are looking for non-metal non-metal bond. those are all covalent bonds. answer is B
P * V = n R T
<span>1 * 2.50 = n * 0.082 * 273 = 2. 50 / ( 0.082 * 273 ) = 0.11 mol </span>
<span>mass = mole number * molecular mass </span>
<span>mass = 0.11 * ( 16 * 2 ) = 3.52 g </span>
Answer:
Turnover number = 113182s⁻¹
Explanation:
Turnover number is a concept used to know the activity of an enzyme. The higher turnover number, the higher activity of the enzime.
Turnover number is defined as:
Turnover number = Rmax / [E]t
As Rmax is 249 μmol⋅L⁻¹⋅s⁻¹ and [E]t is 2.20 nmol⋅L⁻¹
As 1μmol = 1000nmol, Rmax = 249000 nmol⋅L⁻¹⋅s⁻¹. Replacing:
Turnover number = 249000 nmol⋅L⁻¹⋅s⁻¹ / 2.20 nmol⋅L⁻¹
<h3>Turnover number = 113182s⁻¹</h3>
Answer:
It is not an oxidation-reduction reaction. The formation of carbon dioxide and water are redox reactions which involve the oxidation of carbon and hydrogen respectively with oxygen being reduced in both the case.
