Answer:GASEOUS, LOWERING ,EMITTED AS HEAT, DOWN,DO NOT RELEASE,DECREASES,NEGATIVE.
Explanation: Filling the blanks gives
Lattice energy is associated with forming a crystalline lattice of alternating cations and anions from the _GASEOUS___________ ions.
Because the cations are positively charged and the anions are negatively charged, there is a LOWERING of potential- as described by Coulomb's law-when the ions come together to form a lattice energy.That energy is EMITTED AS HEAT when the lattice forms.
As the ionic radii increases as you move DOWN a group, ions cannot get as close to each other and therefore DO NOT RELEASE as much energy when the lattice forms. Thus the lattice energy DECREASES (becomes less) NEGATIVE as the radius increases.
The above gives the definition of Lattice Energy and how it relates to atomic and ion charge.
The answer is 6 each of them has 2 so then you just got to multiply 2 times 3 so it gives you 6
[H+][OH-]=10-¹⁴
We are using this formula because we need to find the H+
substitute the value given for hydronium ion for OH-
[H+][4.19×10⁵]=10-¹⁴
[H+]=10-¹⁴÷4.19×10⁵
[H+]=2.387×10-¹⁹
Then the pH of the solution will be
pH= –log¹⁰ [H+]
pH = –log¹⁰ [2.387×10-¹⁹]
pH= –log¹⁰2.387+19log¹⁰
= –0.378+19
pH =18.622
It is the atomic mass because you add the protons and neutrons together to get this number
Answer:
The mass of the object would be 491.55g/mL. Hope this helped! :)
Explanation:
D= 7.25g/mL M=D•V
V= 67.8mL
M=7.25g/mL•67.8mL
M= 491.55g
