The Bohr model used to be used but it signifies that electrons stay stationary. The current model uses electron clouds in order to predict the location of an electron within an atom.

Additionally, we can predict the location of an electron, but we cannot exactly pinpoint it. So, the current atomic model cannot have a clear and exact placement for every electron around the nucleus of an atom. It also cannot have a clear and distinct border surrounding the nucleus of an atom where electrons are located.

Therefore, the current atomic model has a predicted area surrounding the nucleus where the electron could be located.

The chemical equation for the formation of ammonia is unbalanced.
galben [10]

Answer:

The answer to your question is 2 molecules

Explanation:

Unbalanced chemical reaction

                   H₂(g)   +   N₂(g)   ⇒   NH₃ (g)

         Reactants         Elements          Products

                2                      H                       3

                2                      N                       1

Balanced chemical reaction

                   3H₂(g)   +   N₂(g)   ⇒   2NH₃ (g)

         Reactants         Elements          Products

                6                      H                       6

                2                      N                       2

From the balanced chemical reaction we conclude that when 3 molecules of hydrogen react with one molecule of nitrogen, 2 molecules of ammonia will be formed.

A major computer chip manufacturer has lost its supplier of silicon. Silicon is widely used in the semiconductor industry becaus
-BARSIC- [3]
We know, silicon is a natural semi-conductor, if manufacturer has lost its supplier then they can look for another element which is quite similar to silicon in electronic configuration. 
We should go down the group, next element in 14th group is "Germanium" so we can use that for that purpose.

In short, Your Answer would be "Germanium"

Hope this helps!

A 100 g sample of an unknown liquid absorbs 2000 j of heat energy, raising the liquid's temperature from 50 ◦ c to 70 ◦
Mekhanik [1.2K]
Since there is no phase change, we can use the heat equation,
Q = mcΔT 
where Q is the amount of energy transferred (J), m is the mass of the substance (kg), c is the specific heat (J kg⁻¹ °C⁻¹) and ΔT is the temperature difference (°C).

Q = 2000 J
m = 100 g = 0.1 kg
c = ?
ΔT = (70 °C - 50 °C) = 20 °C

By applying the formula,
2000 J = 0.1 kg x c x 20 °C
         c = 2000 J / (0.1 kg x 20 °C)
         c = 1000 J kg⁻¹ °C⁻¹

Hence, the specific heat capacity of the liquid is 1000 J kg⁻¹ °C⁻¹.
