Answer: equal to the substrate concentration when the reaction rate is half its maximal value.
Explanation: the KM is known as The Michaelis constant. The value of the Michaelis constant KM is numerically equal to the substrate concentration at which the reaction rate is half of Vmax.
The KM value for an enzyme depends on the particular substrate and on environmental conditions such as pH, temperature, and ionic strength.

Check the explanation
Explanation:
Kindly check the attached image below to see the step by step explanation to the question above.
Mg(s)+2HCl(aq)→MgCl2(aq)+H2(g)
(since the molar mass of Mg is not given, assuming that it's mola mass is 24gmol¯1)
1st find the moles of Mg using the equation n=m/M where
n - moles
m - mass
M - molar mass
Therefore :
n = 0.39375mol
n = 0.39mol
Then using the equation n=V/Vm where;
n = mol
V = volume
Vm = molar volume
Find the volume.
n = V/Vm
(n =0.39mol , Vm = 22.4dm³mol¯¹)
V = 0.39mol×22.4dm³mol¯¹
V = 8.736dm³
Answer:
Density of the oil is lesser than that of the water
Explanation:
The density of water is given as 1.0g/cm³.
Salad oil is found to float on water, this implies that the density of this salad oil is lesser than that of the water.
- When the density of a substance is greater than another, it will sink. If the density of the salad oil is greater than that of water, then it will sink and not float.
- Since the oil floats on water, the density of the oil is lesser than that of the water.
Density is the mass per unit volume of a substance.
