Answer:
a.
9.88
Explanation:
ΔG = - 2.303 RT log Ka
ΔG is change in free energy at temperature T , Ka is equilibrium constant
- 56.4 x 10³ = 2.303 x 8.31 x 298 logKa
- log Ka = 9.88 .
pKa = 9.88 .
Answer:
Explanation:The main difference between ionic covalent and metallic bonds is their formation; ionic bonds form when one atom provides electrons to another atom whereas covalent bonds form when two atom shares their valence electrons and metallic bonds form when a variable number of atoms share a variable number of electrons in a metal lattice.
Answer:
When swallowed, the signs and symptoms may include:
Severe burning and associated pain in the mouth, throat, and food-pipe
Drooling from the mouth
Loss of vision; unable to speak
Inflammation of the throat may cause respiratory difficulties
Sudden reduction in blood pressure (hypotension)
Vomiting blood
On skin contact, the signs and symptoms may include:
Severe skin and tissue burns associated with pain
Severe eye burns associated with pain; loss of vision
When inhaled, the signs and symptoms may include:

Heaviness in the chest; chest pain
Bluish discoloration of lips and beneath fingernails
Respiratory difficulties

Headache and weakness
Increased heart-rate
Collapse
Explanation:
Answer:
The higher the excitation state, the more energy the electron contains. When an electron absorbs energy, it jumps to a higher orbital. ... An electron in an excited state can release energy and 'fall' to a lower state.
Hello there!
The correct answer is Ag⁺.
If we look at the solubility rules, it says that most chlorides are soluble, <u>except</u><em> </em>with Ag⁺, and Pb²⁺.
I hope this helps!
