2NaOH + CuBr2 => 2NaBr + Cu (OH)2
Answer:
2. 369 L
Explanation:
1. Combustion is a chemical reaction in which hydrocarbons are burnt in the presence of oxygen to give carbon dioxide and water.
The balanced chemical reaction is:
2. To calculate the moles, we use the equation:
According to stoichiometry :
2 mole of dodecane produces = 24 moles of carbon dioxide
Thus 1.29 moles of dodecane produces = of carbon dioxide
According to ideal gas equation:
P = pressure of gas = 1 atm
V = Volume of gas = ?
n = number of moles = 15.5
R = gas constant =
T =temperature =
Thus the volume of carbon dioxide gas that is produced is 369 L
1. <span>This is called the north-seeking pole of the magnet, or simply the north pole. The opposite end is called the south pole. The needle of a compass is itself a magnet, and thus the north pole of the magnet always points north, except when it is near a strong magnet.</span>
<span>2. Nothing, copper isn't ferromagnetic so magnets aren't attracted to it. </span>
<span>3. The magnet is attracted to it and pulls it to it. </span>
4. A material they make magnets out of and/or a material that magnets are attracted too. The name ferro implies that it is a material with iron in it.
<span>5. <span>Electric motors are only possible because of synchronized magnets chasing each other that causes the motion of the motor. </span></span>

Answer:
Heat energy.
Explanation:
The exited electron releases the absorbed energy as heat energy that provides energy to electrons to move from one orbit to another orbit. The electron avails kinetic energy which provides motion in the electron when the energy is absorbed by the electron while on the other hand, electron releases energy which brings the electron into its original orbit. So we can say that the electrons releases energy in the form of heat and come back to its original place.
