1 mole Zn ---------- 6.02 x 10²³ atoms
0.750 moles Zn ----- ?
atoms = 0.750 * ( 6.02 x 10²³ / 1 )
= 4.515 x 10²³ atoms
hope this helps!
Answer:
D/CH3COOH
Explanation:
CH3COOH is a weak acid, it partially dissociates into its ions in an aqueous solution.
Answer:
H2
Explanation:
In the first place it is necessary to consider that these two elements will be their diatomic form initially, that is, H2 and N2.
first we should check the equilibrium constant Kp tables in this case at a temperature of 3000K
Value for dissociation reaction of H2 in Kp = -3.685
Value for dissociation reaction of N2 in Kp = -22.359
Equilibrium constant for H2 dissociation is higher than N2 dissociation. so for this comparation H2 is more likely to dissociate.
Answer : Option A) The lattice energy increases as cations get smaller, as shown by LiF and KF.
Explanation : It is observed that lattice energy is mostly influenced by two main factors of an ionic solid which are;
i) The charge on the ions - As the charge of the ions increases, the lattice energy is observed to increase too.
and
ii) The radius, or size, of the ions - As the size of the ions increases, the lattice energy decreases with it.
So, here in this question the second reason is clearly observed. Hence, it is self-explained that the size of the cations are decreased in the ionic solids the lattice energy increases.
