Chemistry
1 answer:
sdas [7]3 years ago
7 0

The four metals that will not replace hydrogen in an acid are Cu, Ag, Au, Hg.

Explanation:

  • As Copper Cu lies below the hydrogen, this is why it is less reactive and ca not replace Hydrogen from its compound.
  • Silver Ag also lies below the hydrogen and therefore it is less reactive to displace Hydrogen.
  • Gold Au becomes less reactive than Hydrogen due to its placement below Hydrogen acid.
  • Mercury Hg is less reactive than Hydrogen

How is the electron cloud model different from Bohr's atomic model?
Vesnalui [34]

Answer:

While Bohr's atomic model hypothesizes that electrons move in particular energy levels around the nucleus, the electron cloud model suggests that electrons move in an unpredictable pattern but are more likely to be in certain regions than others.

Their weights could be different.
Their volumes could be different. 
Their densities could be different.

The volume for an ounce of lead is much different than an ounce of aluminum.

the weight of a cubic meter of balsa wood is much different (and much lighter) than a cubic meter of water. That's why the ancients used balsa for their rafts.

1. Which of the following indicates the number of protons?
Leokris [45]

Answer:

a)Atomic number

Explanation:

Element symbol signifies the element. For eg, Na is sodium. Mass number is the sum of protons and neutrons of an atom of an element. Atomic mass is the molar mass of the given element. Finally, atomic number is unique to each element because it signifies the number of protons of that element. EACH ELEMENT has their UNIQUE number of protons. For eg, atomic number of hydrogen is 1 because it has 1 proton, NO OTHER ELEMENT HAS ATOMIC NUMBER 1 because NO OTHER ELEMENT HAS 1 proton.

What did Thomas Young, Max planck and Albert Einstein contribute towards the nature of light?
Lera25 [3.4K]

The contribution to the nature of light-

Thomas Young - wave nature of light (double-slit experiment)

Max Planck - E = hv

Albert Einstein - a quantum theory of light

Thomas Young proposed the most important double-slit experiment which shows that light acts like a wave and shows the pattern of interferences.

Max Planck proposed that light is proportional to frequency. He gave the equation, E = hv, where E is the energy of light, h is Planck's constant, and v is the frequency.

Albert Einstein proposed the quantum theory of light. He determined that light exists in discrete quanta of energy called photons.
