If you look at the periodic table today which elements would best represent a triad as predicted by Dobereiner? A. Hydrogen Oxygen Nitrogen
B. Nickel Copper Zinc
C. Aluminum Gallium Indium
D. Neptunium Plutonium Americium
E. All of them are triads
HELP ME PLEASE

 B. Nickel Copper Zinc

Explanation:

Dobereiner's triads was a group of three elements. Dobereiner said that the relative atomic mass of the middle element in each triad was average of the relative atomic masses of the other two elements.

Thus if A, B and C forms Dobereiner's triads, the mass of B is average of mass of A and C.

A. Hydrogen Oxygen Nitrogen:

mass of oxygen = 15.999

mass of oxygen according to Dobereiner =

B. Nickel Copper Zinc

mass of copper = 63.5

mass of copper according to Dobereiner =

C. Aluminum Gallium Indium

mass of gallium = 69.72

mass of gallium according to Dobereiner =

D. Neptunium Plutonium Americium

mass of Plutonium = 244

mass of Plutonium according to Dobereiner =

no, i was listening to water by schoolboy q while and i saw this question

explenation:

water isn't wet. wetness is a description of our experience of water; what happens to us when we come into contact with water in such a way that it impinges on our state of being. we, or our possessions, 'get wet'. a less impinging sense experience of water is that it is cold or warm, while visual experience tells us that it is green or blue or muddy or fast-flowing. we learn by experience that a sensation of wetness is associated with water: 'there must be a leak/i must have sat in something.'

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
