To investigate the relationship between enzyme activity and substrate concentration, a student is supposed to prepare a reaction

nikdorinn [45]

As i know for finding the speed of an enzyme to do it's work this formula is used
v=v max *[s]/k m +[s]
km shows the amount of substrate we need to make the enzyme work with half of it's max speed and [s] shows the substrate.
we can say that 0.025/0.25=0.1 so the speed is about 0.1 of we wanted to 
investigate at the beginning (we don't consider [s] in the Denominator to solve it easier)

Draw the lewis structure for the polyatomic trisulfide s−23 anion. be sure to include all resonance structures that satisfy the

mezya [45]

The following are the steps involved in drawing Lewis structure of the polyatomic trisulfide anion $S_{3}^{2-}$ :

Total number of valence electrons = $(3 * 6) + 2 = 20 electrons$

Resonance is not possible in this ion. The molecular geometry of the ion will be bent as there are two lone pairs and two bond pairs on the central atom.

Balance the following equations 1.Na+HCI=NaCI+H2 2.Mg+O2=MgO

liberstina [14]

Answer:

1. 2Na + 2HCl = 2NaCl =H2

2. 2Mg + O2 = 2MgO

Explanation:

make sure that the number of atoms of each element is the same on each side of the equation

1. 2Na + 2HCl = 2NaCl =H2

on LHS of equation,

Na = 2

H = 2

Cl =2

On RHS of equation,

Na=2

H= 2

Cl =2

2. 2Mg + O2 = 2MgO

on LHS of equation,

Mg = 2

O2 = 2

On RHS of equation,

Mg = 2

O2 = 2
