Answer:

D. The behavior of an atom's electrons can be described by circular orbits around a nucleus.

Explanation:

<em>Which of the following statements is INCORRECT? </em>

<em>A. It is not possible to know the exact location of an electron and its exact energy simultaneously.</em> CORRECT. This is known as the Heisenberg's uncertainty principle.

<em>B. The energies of an hydrogen atom's electrons are quantized.</em> CORRECT. According to the modern atomic model, the energy levels are quantized, that is, they have a discrete amount of energy.

<em>C. The wave mechanical model correctly predicts all the energy states and the orbitals available to an electron in an hydrogen atom.</em> CORRECT. The characteristics of the energy levels are explained by Schrödinger's wave equation.

<em>D. The behavior of an atom's electrons can be described by circular orbits around a nucleus.</em> INCORRECT. This was postulated by Bohr's atomic model but it is now considered to be incorrect.

<em>E. Electrons have both wave and particle properties.</em> CORRECT. This is what De Broglie called wave-particle duality.

What contribution to atomic theory resulted from albert einstein’s work?
Hatshy [7]

Answer:

Albert Einstein is perhaps most famous for introducing the world to the equation E=mc2. In essence, he discovered that energy and mass are interchangeable, setting the stage for nuclear power—and atomic weapons. His part in the drama of nuclear war may have ended there if not for a simple refrigerator.

How many moles of ammonia can be formed from 4.0 mol H2
Bess [88]

Answer: 1. 2.7 moles  of ammonia are formed

2. 12.0 moles  of hydrogen are required

3. 2.0 moles of nitrogen are required

Explanation:

The balanced chemical equation is:

N_2+3H_2\rightarrow 2NH_3

According to stoichiometry:

3 moles of hydrogen form = 2 moles of ammonia

Thus 4.0 moles of hydrogen form =\frac{2}{3}\times 4.0=2.7moles of ammonia

According to stoichiometry:

2 moles of ammonia are formed by = 3 moles of hydrogen

Thus 8.0 moles of ammonia are formed by  =\frac{3}{2}\times 8.0=12.0moles of hydrogen

According to stoichiometry:

3 moles of hydrogen react with = 1 mole of nitrogen

Thus 6.0 moles of hydrogen react with =\frac{1}{3}\times 6.0=2.0moles of nitrogen

emmasim [6.3K]

Answer:

Explanation:

Upon arrival we needed to hunt in this new land we only had five refills and they needed 50 g of gunpowder to be shot once. We only have 15 pounds of gunpowder. It is taking six shots to kill one of these wild turkeys. How many turkeys can be shot with 15 pounds of gunpowder?

If we had plenty of refills, and it takes 6 shots to kill a wild turkey at 50 gms of gunpowder per shot, then each turkey requires 6X50 =300gms of gunpowder.  We have 15X454 gms of gunpowder and have the potential to kill 15X454/300=22.7 or 22 turkeys.and it takes 6 shots to kill a wild turkey.

The limiting reagent is the number of refills, and withonly 5, we are out of luck and can't kill one turkey
