Molar mass beryllium iodide ( BeI₂ ) = <span>262.821 g/mol
mass = number of moles * molar mass
mass = 0.02 * 262.821
mass ( BeI</span>₂) = 5.25642 g

Answer
is: concentration of hydrogen cations in lemon juice is 4.00 × 10−3 m.
pH
= 2.4.
pH
= -log[H₃O+].
[H₃O+] = 10∧(-pH).
[H₃O+] = 10∧(-2.4).
[H₃O+] = 0.004 mol/L.
pH value (potential of hydrogen - [H+]) is a logarithmic scale that
specify the acidity or basicity of an aqueous solution. When pH is greater than
seven, aqueous solution is basic, below seven is acidic and when pH is equal
seven, solution is neutral.
Answer:
Glucose and glycogen.
Explanation:
Hello,
Monomers are the functional molecules forming the polymers when an random amount of units (monomers) are linked form an assembly (polymer).
This could be exposed by considering the glucose as the monomer forming the glycogen which is a polymer that serves as a form of energy storage in animals, fungi, and bacteria; it is constituted by about 30,000 units of both lineal and branched glucose which provide many features that the glucose doesn't have by itself.
Best regards.
The answer is D, wavelength
