Answer: 6 moles
Take a look at the balanced chemical equation for this synthesis reaction
N 2(g] + 3 H 2(g] → 2 NH 3(g]
Notice that you have a 1:3 mole ratio between nitrogen gas and hydrogen gas. This means that, regardless of how many moles of nitrogen gas you have, the reaction will always consume twice as many moles of hydrogen gas.
So, if you have 2 moles of nitrogen taking part in the reaction, you will need
2 moles N 2 ⋅ 3 moles H 2 /1 mole N 2 = 6 moles H 2
2.
The reason why is because there are 2 available electron spots on the orbital for the oxygen atom. Hydrogen atoms have one proton and one electron, thus, in order to fill the oxygen atom orbital to a full outer shell, a maximum of 2 atoms could bond with the oxygen atoms.
6 electrons (oxygen)+ 1 electron (hydrogen)+ 1 electron (hydrogen)= 8
A balance in a lab measures the weight of a substance or object.
Weight is the mass of the body x the gravitation pull on the mass of the object.
So the mass of the object can be found by dividing the weight by gravitational constant.
The gravitational constant on earth is 1. so if a balance says that a substance weighs 300g then its mass is also 300g on earth because 300/1 = 300.
Hope that helps :)
This type of energy travels through vibrations on waves = 7. sound energy
This is the energy found in the nucleus of an atom = 9. nuclear energy
This type of energy can be transferred in three different ways = 6. thermal energy
This is the term used when energy changes from one form to another = 10. energy conversions
This has to do with the speed of an object and how much mass it has = 2. kinetic energy
This can be either kinetic or potential and has to do with the energy of position and motion of an object = 1. mechanical energy
This type of energy is stored energy = 3. potential energy
This is radiant energy from the sun = 5. light energy
This is energy that is transferred by the movement of electrons through a conductor = 4. electrical energy
This type of energy is often found in things like batteries or food = 8. chemical energy
