Answer:
An ignition coil can fail due to a high voltage puncture of its body, or an open primary or secondary winding. A few are killed by overheating when the control side of the primary side develops a short to ground. Something as simple as badly worn spark plugs will increase the demand from the coil, and eventually lead to failure.
But if I were to discuss the current leading cause of ignition coil replacement, I would have to say misdiagnosis and bad internet information. This is especially true of modern “coil on plug” systems. Often, the actual coil is fine, and the only damage is the replaceable spark plug boot.
I've seen countless examples of online “advice” to start with replacing all spark plugs and coils at the suggestion of any power loss or hiccup. Then the car owner purchases the cheapest set of coils that they can find. Not only is the initial problem still present , but they likely WILL have a future misfire due to poor quality parts selection. All misfires are not caused by coils and spark plugs.

The bond between which two atoms is most
polar?
(1) C-0
(3) H-O
(2) F-F
(4) N-H
TOITTI
The bond between hydrogen (H) and oxygen (O) (option 3: H-O) has the highest electronegativity difference (1.24). Therefore, the H-O bond is the most polar among the given choices.
The polarity of a chemical bond depends on the electronegativity difference between the two atoms involved. The greater the electronegativity difference, the more polar the bond.
Let's compare the given bond options:
(1) C-O: The electronegativity of carbon (C) is approximately 2.55, and the electronegativity of oxygen (O) is approximately 3.44. The electronegativity difference is 0.89.
(3) H-O: The electronegativity of hydrogen (H) is approximately 2.20, and the electronegativity of oxygen (O) is approximately 3.44. The electronegativity difference is 1.24.
(2) F-F: Fluorine (F) is the most electronegative element with an electronegativity of 3.98. Since both atoms in this case are fluorine, the electronegativity difference is 0.
(4) N-H: The electronegativity of nitrogen (N) is approximately 3.04, and the electronegativity of hydrogen (H) is approximately 2.20. The electronegativity difference is 0.84.
From the options provided, the bond between hydrogen (H) and oxygen (O) (option 3: H-O) has the highest electronegativity difference (1.24). Therefore, the H-O bond is the most polar among the given choices.

An electrically neutral atom has an atomic mass of 30.973 and an atomic number of 15. How many neutrons does this atom have?_______________
Answer: 16 neutrons
Explanation: The atomic number for any element is the number of protons in its atomic nuclei. In a neutral atom, the number of electrons are the same as the number of protons. The atomic mass (mass number) is the sum of the protons and neutrons in the nucleus. Mass number can vary due to the fact that the number of neutrons can vary. Isotopes are named for their mass numbers.
So, this element has 15 protons (atomic number), 15 electrons, and 16 neutrons (mass number minus atomic number).
This isotope is phosphorus-31, which has atomic number 15.

When 2 moles of Mg3N2 are allowed to react, how many moles of H20 also react?
Mg, Na(s) + 6H20(1)
3Mg(OH)2(s) + 2NH3(g)
1 mole
4 moles
6 moles
8 moles
12 moles
Answer:
12 moles of water (E)
Explanation:
The first step is to see that the equation is balanced. It is now, but you did something strange to the Mg3N2.
Mg3N2(s) + 6H20(l) ======> 3Mg(OH)2(s) + 2NH3(g)
What the equation is telling you is that 1 mol of Mg3N2 requires 6 moles of water for the reaction to occur.
So 2 mols of Mg3N2 would require 6*2 mols of water to react.
The answer is 12 moles of water

Which of the following is most likely to dissolve in NH3? A) CO2 B) CH4 C) H2S D) BH3
Answer:
C) H2S
Explanation:
In chemistry, the dissolution of one substance in another is dependent on the magnitude of intermolecular interaction between the two substances. Hence, if two substances do not interact in one way or the other, then one can not dissolve the other.
Let us consider the fact that NH3 is a polar molecule and it is a general principle that like dissolves like. Hence, only H2S which is also a polar molecule can effectively interact with NH3 due to dipole-dipole interaction between the two molecules.
Also, ammonia reacts with hydrogen sulphide as follows;
2NH3 + H2S → (NH4)2S
Hence H2S is more likely to dissolve in NH3.

Most physical and chemical changes in matter include a change of energy true or false
Answer: true
Explanation:
Energy changes are a common component of physical and chemical changes in matter. Hence the statement is True.
Briefing:Physical changes and chemical changes are the two different types of changes that chemists examine. A substance can undergo physical changes without having its identity altered. Chemical transformations take place when one substance transforms into another.
Which is a chemical change?When one chemical material changes into one or more others, as when iron rusts, this is referred to as a chemical transformation. Chemical reactions produce changes in the way that atoms and molecules are ordered, which leads to the formation of new substances with new properties.

Hillsdale and Cordera are the same distance from the equator, and both are near the ocean. Is Cordera warmer, colder, or the same temperature as Hillsdale? Explain using wrods energy level, temperature, current
Answer:
Cordera is colder than Hillsdale.
Explanation:
They may be at a similar latitude. But you also have to consider the currents nearby the location.
The prevailing wind closer to the equator which carries warm current hits Hillsdale which is why it follows the coastline of the continent. However, for Cordera prevailing winds carrying cold currents hits the continent and follows or hits the coastline of Cordera.

What is the highest sublevel for the element Boron?
Answer:
2p
Explanation:
Boron is a member of group 13. The highest energy sub-level is usually found on the outermost shell of the atom of the element involved.
For a group 13 element, its outermost shell configuration is ns2 np1. The electronic configuration for boron is; 1s2 2s2 2p1.
Hence the highest energy sub-level in boron is 2p.
