<h2>Answer:</h2>
<u>Decreasing Ionization energy</u>
<h2>Explanation:</h2>
As elements of Group 1 of the Periodic Table are considered in order from top to bottom, the ionization energy of each successive element decreases. This decrease is due to increasing radius and increasing shielding effect. In other words when we move to the right of a period, the number of electrons increases and the strength of shielding increases. As a result, it is easier for valence shell electrons to ionize, and thus the ionization energy decreases down a group.
Atoms make up the mass of all materials
Atoms cannot be created or destroyed
So in a balanced chemical equation, all atoms are accounted for, and therefore all mass is accounted for and conserved.
Answer:
0.5 moles
Explanation:
u will get molar mass = 95.2 I think
then number of moles = molar mass÷ mass
=95.2÷180=0.5
Answer:
We know that kinetic energy is one of the forms of internal energy, so the release of heat from an object causes a decrease in the average kinetic energy of its particles.
Answer:
C
In an exothermic reeaction, the energy of products is less than the energy of reactants.
