Why do scientist use models to study atoms

Scientist use models to study atoms because you cannot either see or perceive directly what do atoms look like.

Models permit to explain in a simplified way how the atoms are constituted, and, so, figure out how they behave and how they are the bulding blocks of the matter (elements and compounds).

A model can be a drawing or structure with balls and sticks, which show in an idealized way what an atom is.

Since the scientists have discovered different facts about the atoms along the last 200 years the models of the atoms have also evolved.

The plum pudding model of the atom proposed by JJ Thompson was different of the nuclear model proposed by Rutherford, and Rutherford's was different from the planetary model proposed by Bohr, and this is different from the quantum model.

Models are used to study atoms because we can never really see an atom up close, and a model is like a super magnified version of the atom. Plus, its easier to study from them because we can pin point the different characteristics of the atom (Protons, Neutrons, etc.)

gregori [183]

Answer:

The atmosphere is the superhighway in the sky that moves water everywhere over the Earth. Water at the Earth's surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.

Explanation:

If you don't want to plagiarize change it up a bit.

The decomposition reaction of A to B is a first-order reaction with a half-life of 2.42×103 seconds: A → 2B If the initial conce
kipiarov [429]

Answer:

t=23.5min

Explanation:

Hello,

In this case, since the rate equation turns out as shown below due to the first-order kinetics:

\frac{dC_A}{dt}=-kC_A

Its integration results:

\int\limits^{C_A}_{C_A^0} { \frac{dC_A}{C_A}} \,=-k\int\limits^t_0 {} \, dt\\ln(\frac{C_A}{C_A^0})=-kt

However, the rate constant is computed by considering the given half-life time as follows:

k=\frac{ln(2)}{t_{1/2}}=\frac{ln(2)}{2.42x10^3s}=2.86x10^{-4}s^{-1}

In such a way, the required time in minutes to diminish the concentration by 66.8% of the initial turns out:

C_A=0.668C_A^0

ln(\frac{0.668C_A^0}{C_A^0})=-kt

t=\frac{-ln(0.668)}{2.86x10^{-4}s^1}=1408.3s*\frac{1min}{60s} \\t=23.5min

Best regards.

On a warm summer day in Helsinki, the temperature is 20°C and the relative humidity is 40%. What is the absolute humidity? Numbe
arsen [322]

Answer:

For the resolution of these questions, it necessary to get the information from the well known humidity charts that allow us to accurately and quickly know all the values required for being able to use these values in other more specific procedures, then the values obtained are getting as:

absolute humidity = 0.0069 kg/kg air

humid volume = 128.7 m3 /kg dry air

specific enthalpy = 36.64 kJ/kg
