9L!!! You take the moles of N2 in the reaction and then divide by one mole of nitrogen. Then you multiply that by the number of hydrogen moles in the reaction which in this case is 3. This gives you an answer of 3. You then take the number of hydrogen moles and multiply it by the 3L giving you 9L of hydrogen.
Potential Energy is the stored energy in an object or system because of its position or configuration. Kinetic energy of an object is relative to other moving and stationary objects in its immediate environment.
A car sitting still
The distance is not changing which means the car is not moving
1. The subscript when writing the notation is always dedicated to the atomic number of the element. Since the atomic number for Mercury, Hg, is 80, then the subscript is <em>80</em>.
2. For the second problem, you just have to balance out the subscripts and superscripts of the reactions.
Superscripts: 203 = 203 + ?; To balance, the missing number would be 0.
Subscripts: 80 = 81 + ?; To balance, the missing number would be -1.
<em>Hence the particle produced is actually an <u>electron</u>, or a <u>beta particle</u> (not an element). The <u>mass number is 0</u>, and the <u>atomic number is 0 </u>(since it does not contain any proton).</em>
A plasma is an ionized gas, a gas into which sufficient energy is provided to free electrons from atoms or molecules and to allow both species, ions and electrons, to coexist
