Answer:
Explanation:
Lattice energy is the energy required to separate one mole of an ionic solid compound into its components gaseous cations and anions.
Due to increase in size of the ions, the lattice energy decreases while the lattice energy increases as the charge of the ions increases.
When the size increase, the distance between the nuclei also increase leading a decrease the force of attraction between the nuclei
Answer:
e. a
Explanation:
im not sure if this is right
Answer:
204 kJ
Explanation:
Heat energy can be calculated using
Q=mcθ
where Q = Heat energy
m =mass
c = specific heat capacity
θ =temperature difference
Q = 12 * 1700*10
= 204000 J
= 204 kJ
Answer:
increases.
Explanation:
As a ball falls freely towards the ground, it's kinetic energy increases. If the kinetic energy increases, that means the object hasn't hit the bottom yet. If the ball continues to fall freely towards the ground, the air gives it more pressure, after that the pressure begins to increase.
