The molar volume is the volume occupied by 1 mol of any gas at STP.
The molar volume is 22.4 L
The volume occupied by 1.00 mol is 22.4 L
Therefore the volume occupied by 3.00 mol is - 22.4 L x 3 = 67.2 L
The answer is that 3.00 mol of gas particles occupy a volume of -
D. 67.2 L
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.
Explanation:
Answer is: 3) H2O and HCl.
Polar molecules are water (H₂O) and hydrochloric acid (HCl).
Nonpolar molecules are carbon(IV) oxide (CO₂) and methane (CH₄).
Carbon(IV) oxide is nonpolar because CO₂ is linear molecule and the oxygen atoms are symmetrical (bond angles 180°).
Water is polar because of the bent shape of the molecule.
Hydrochloric acid has polar covalent chemical bond where hydrogen has oxidation umber +1 and chlorine oxidation number -1.
In molecule of methane (CH₄) all the atoms around the central element (carbon) are equivalent (four hydrogens) and it has a net dipole moment of 0 (vectors of dipole moments cancel each other, dipole moment is zero).
Answer:
Friction
Explanation:
Energy is lost to heat as the object overcomes kinetic friction as it slides up the ramp. The energy loss is equal to the work done by the friction force.
