Answer:
Gallium, Germanium, Arsenic, Selenium, Bromine and Krypton
Explanation:
Based on periodic trends, the atom that has a larger ionization energy than calcium are Gallium, Germanium, Arsenic, Selenium, Bromine and Krypton.
Across the period, the ionization energy increases from left to right.
- Ionization energy is the energy required to remove the most loosely held electron within an atom.
- As you go from left to right, the ionization energy increases rapidly.
- The elements to the right of Ca will have a higher ionization energy compared to Ca.
Exothermic:
An Exothermic reaction is a chemical reaction that expels energy in the form of heat/light. Everything a Endothermic does not do. Pretty simple for this one
reactants → products + energy.
For future reference - Exo means release, thermic means heat.
<u>Energy is a Reactant </u>

<u>_________________________________________________________</u>
Endothermic:
An Endothermic reaction essentially is draining the heat energy from anything its its surroundings. Usually its just heat but can also be salt dissolving it water or ice melting. Another example would be frost on your windshield evaporating.
It is the exact opposite of an Exothermic reaction.
<u>Energy is a Product</u>
It is 3 moles. Don't doubt urself
Answer:
Explanation:
Hello!
In this case, since the reaction between phosphorous and oxygen to form diphosphorous pentoxide is:
Thus, since phosphorous is in excess and oxygen and diphosphorous pentoxide are in a 5/2:1 mole ratio, we can compute the maximum moles of product as shown below:
Best regards!
The implications are for this reader in this line is that the atom is belonging to some kind of system and it is good belonging to that system.
Hope this helps. :)
