Substances that posses an excess it greater amount of hydroxide ions are considered basic, or alkali like in solution. They would thus showcase properties of a basic substance.
The correct answer for the question that is being presented above is this one: "Electrovalency is characterized with the transferring of one or more electrons from one atom to another together with the formation of ions and as well as the number of positive and negative charges.
The Lewis and Langmuir theory of electrovalency (and as well as Kossel's) is dealing with Ionic bonds.
Lewis: electron-pair sharing, octet rule, Lewis Symbols or StructureLangmuir: introduced term "covalent" bond, and popularized Lewis's ideas
The Lewis-Langmuir electron-pair or covalent bond is referred as the homopolar bond, where the complete transfer of electrons give rise to ionic, or electrovalent bond (1) through attraction of opposite charges.
Answer:
C = 107.97 mol/L
Explanation:
Given data:
Volume of solution = 1.38 mL (1.38 mL× 1 L /1000 mL = 0.00138 L)
Mass of ammonium sulfite = 17.36 g
Concentration of solution =?
Solution:
We will calculate the number of moles of ammonium sulfite.
Number of moles = mass/molar mass
Number of moles = 17.36 g / 116.15 g/mol
Number of moles = 0.149 mol
Concentration:
C = n/V
C = concentration
n = number of moles of solute
v = volume in L
C = 0.149 mol / 0.00138 L
C = 107.97 mol/L
Is there a picture of the model? Who's Dalton? What other models? Please explain and give answer choices if you can--- that'll help you help you here on Brainly!
PS.: When you do give answer choices, I'll comeback and try my best to answer for you.
Answer:
Explanation:
for spontaneous reaction,
ΔG is negative
K>1
E > 0
cell A:
ΔG and EO suggests that reaction is spontaneous. But K is less than 1.
Hence K is wrong
cell B:
ΔG and EO suggests that reaction is non spontaneous .But K is greater than 1.
Hence K is wrong
cell C:
E and K suggest than reaction is non spontaneous but ΔG suggest that reaction is spontaneous.
Hence ΔG is wrong
