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

1 answer:

4 0

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.

What are the mole ratios?<br> 2 Mg +10, → 2 Mgo

Gala2k [10]

Answer and explanation:

The mole ratio for Mg and MgO would be 2:2 or 1:1 because Mg has 2 as a coefficient and so does MgO, which is why you can simplify the ratio to 1:1

The mole ratio for O and MgO would be 1:2 because O has 1 as the coefficient and MgO has 2 as a coefficient.

The balanced chemical equation for the reaction between PCl5 and water is given below. If 3.45 moles of HCl are produced, how ma

enyata [817]

The coefficients of the substances give you the ratio of the number of moles.
The 4 before the H2O and the 5 before the HCl tell you that for every 5 moles of HCl created, 4 moles of H2O had to react.

Therefore:
$(3.45mol HCl)(\frac{4 mol H2O}{5 mol HCl})$
can be used to find the moles of H2O that react.

$(3.45mol HCl)(\frac{4 mol H2O}{5 mol HCl}) = 2.76 mol H20$

How many moles are 7 grams of calcium oxide? (Atomic mass of Calcium - 40 u, oxygen-16 u)

White raven [17]

Answer:

0.125

Explanation:

no of moles = given mass / molar mass

no of moles = 7/

molar mass of calcium oxide = atomic mass of calcium + oxygen

molar mass = 40 + 16

molar mass = 56

no of moles = 7/ 56 = 1/8 = 0.125
