Answer:

The Nitrogen has 7 neutrons.

Explanation:

The Atomic Number is the number of protons of an atom and is represented by Z, so:

Z = number of protons

Z = 7

The Atomic Mass is the sum of the number of protons and the number of neutrons, and is represented by A, so:

A = number of protons + number of neutrons

A = 14

And from A we have that the number of neutrons is:

Number of neutrons = A - number of protons

Number of neutrons = A - Z

Number of neutrons = 14 - 7

Number of neutrons = 7

Sauron [17]

Answer:

c) that the formation and decomposition of ES is the same for a period of time

Explanation:

Michaelis-Menten equation :

This model  explain the approach to enzyme kinetics.The Equation shows how a Free enzyme E and Product P is formed depicting by Following equation.

                       E+S⇌ES→E+P

Left side represents

E =enzyme

S=substrate

ES=enzyme-substrate complex

Right side

E= Free enzyme

P= product

c) that the formation and decomposition of ES is the same for a period of time

Would the amount of solid magnesium increase decrease or stay the same if you added a strong acid to it?
Vlada [557]
Solid Magnesium is considered as active metal so it reacts with strong acids like HCl and H₂SO₄ liberating Hydrogen gas according to the following equations:

Mg(s) + 2 HCl(aq) → MgCl₂(aq) + H₂(g)
Mg(s) + H₂SO₄(aq) → MgSO₄(aq) + H₂(g)

so the amount of solid magnesium decrease  by addition of strong acid to it.
