The two-step mechanism of reaction consists of fats and slow steps. Products of fast step in reaction build up in concentration resulting in an equilibrium condition.
<h3>What is a reaction mechanism?</h3>
A reaction mechanism is defined as a theoretical model that represents the sequence of the chemical process that forms products from reactants.
In a mechanism involving two steps, if the fast step precedes the slow step then, its product will be accumulated in the reaction mixture which will affect the reaction equilibrium.
Therefore, if a fast step precedes then the product affects the equilibrium.

B) Repeated experiments that show the same results are less likely to contain experimental errorli
The equation for calculating a mass is as follows:
m=n×M
Molar mass (M) we can determine from Ar that can read in a periodical table, and a number of moles we can calculate from the available date for N:
n(H2SO4)=N/NA
n(H2SO4)= 1.7×10²³ / 6 × 10²³
n(H2SO4)= 0.3 mole
Now we can calculate a mass of H2SO4:
m(H2SO4) = n×M = 0.3 × 98 = 27.8 g
Answer:
A. By the circumference of the epicenter
Explanation:
If the Earth's lithospheric plates begin to move slowly, stresses emanate in the crust, most at times close to the plate boundaries. These stresses (compression, tension strain, and shear) accumulate in the crust until they surpass the rock's strength or the pressure around an internal fault. And there's a sudden slippage of rock around a fault.
The planet shakes and the rocks lurch to their new position in a matter of seconds as the stress energy is released. Seismic waves move away from the broken portion of the fault, just like ripples from a pebble landing on calm water.
Seismologists may estimate when the slippage started on a fault, the area of the slipping fault, the sum of slippage or fault throw (i.e. just how much the crust moved), and the length of time it takes for the slippage to happen by measuring the circumference of the epicenter which is the mapped area where the earthquake is taken place.
