Answer: A weak acid titrated by a strong base

Explanation:

The graph refers to the titration of a weak acid such as Hydrofluoric acid with a strong base such as Sodium Hydoxide. What happens is that as the process begins, the pH rises quickly as there is little resistance to the base.

After some time the solution formed begins to act as a buffer between the remaining acid and the base. This reduces the pH change rate and will continue until the base overcomes the solution's buffering capacity.

The Equivalence point which is where the acid will be at it's base form, will be at a pH of 8.6.

I have attached a graph showing the process for better understanding.

What are the four most common problems that can arise in your motor design?

Nuetrik [128]

Electric motors are an essential part of our daily life as many systems, applications, and services depend on them. Motors today have a long service life and require a minimum level of maintenance to make sure that they perform efficiently. In large buildings, motors have to be maintained on a regular basis because they need to be in operation all the time; one small problem could cause a great loss to the organization.

Usually in large organizations, a motor maintenance program is carried out in which the causes of motor failures are identified and some necessary steps are taken to avoid them or lower their impact. Motors need to be inspected regularly, and other maintenance activities need to be performed to ensure efficient operation. Whenever a problem occurs, it should be corrected immediately to avoid further loss.

1. Consider the decomposition reaction of sodium chlorate. There are 100 grams of

IRINA_888 [86]

A. NaCl(s) and O2(g)

B. 2NaClO3(s) —> 2NaCl(s) + 3O2(g)

C. moles NaClO3 = 100 g / 106.44 g/mol = 0.939 mol NaClO3

D. 0.939 mol NaCl (because the NaClO3 and NaCl are in a 1 to 1 ratio)

E. grams NaCl = 0.939 mol • 58.44 g/mol = 54.9 g NaCl

F. moles of O2 = 0.939 mol NaClO3 • (3 mol O2 / 2 mol NaClO3) = 1.41 mol O2

G. grams of O2 = 1.41 mol • 32 g/mol = 45.1 g O2

H. Percent yield = 10/45.1 • 100% = 22.2% yield
