CHEMICAL ENERGY
Energy, potential energy, is stored in the covalent bonds holding atoms together in the form of molecules. This is often called chemical energy.
Chemical energy is the energy of chemical substances that is released when they undergo a chemical reaction and transform into other substances. Some examples of storage media of chemical energy include batteries, food, gasoline, and oxygen gas.
Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds.Physical changes occur when objects or substances undergo achange that does not change their chemical composition.
Yes because the force or the pressure of the cart is getting doubled therefore it makes the speed or the net force harder
Answer:
11.29 kJ (to 4 sf)
Explanation:
Here, ammonia is the limiting reactant.
For the reaction to occur once, 4 moles of ammonia must be consumed.
Thus means that the reaction can occur 0.1579/4=0.039475 times.
Therefore, (286)(0.039475) = 11.29 kJ (to 4 sf)
