Answer:
The Michaelis‑Menten equation is given as
v₀ = Kcat X [E₀] X [S] / (Km + [S])
where,
Kcat is the experimental rate constant of the reaction; [s] is the substrate concentration and
Km is the Michaelis‑Menten constant.

Answer:
The correct option is D.
Explanation:
Radioactive substances usually emit different types of particles when they are decaying. Such particles include alpha particles, beta particles and gamma ray. When an alpha particle is emitted from an unstable radioactive nucleus such nucleus usually lost an atomic mass that correspond to that of helium atom. Note that an alpha particle is made up of two protons and two neutrons, which result in mass number of 4. Thus, a nucleus that emit an alpha particle will have its mass number (atomic mass) reduce by 4 and atomic number that is reduced by 2.
The new volume if the balloon is cooled at constant pressure is 3.98 L
<u><em>Explanation</em></u>
The new volume is calculated using the Charles law formula
that is V1/ T1 = V2/T2 where,
V1 = 4.24 l
T1= 23c into kelvin = 23 +273 =296 K
T2 = 5.00 c into kelvin = 5.00 + 273 = 278 K
V2 = ?
by making V2 subject the subject of the formula by multiplying both side by T2
V2 = V1 xT2/ T1
V2 = (4.24 L x 278 K) / 296 k =3.98 L
The k is the proportionality constant of the reaction. Graphically, this is the slope of the graph. Since the graph is linear, then there is only 1 value of k. To calculate this, choose two random points in the line. Suppose we use (0.15,10) and (0.30,20), calculate for the slope.
Slope = k = (10 - 20)/(0.15 - 0.30) = 66.67 mL CO₂/g CaCO₃
