Answer is: Rutherford demonstrate that J.J Thompson's Plum Pudding model was not accurate.

Rutherford theorized that atoms have their charge concentrated in a very small nucleus.

This was famous Rutherford's Gold Foil Experiment: he bombarded thin foil of gold with positive alpha particles (helium atom particles, consist of two protons and two neutrons).

Rutherford observed the deflection of alpha particles on the photographic film and notice that most of alpha particles passed straight through foil.

That is different from Plum Pudding model, because it shows that most of the atom is empty space.

3. A 4.00 gram sample of solid gold was heated from 274K to 314K. How much energy was involved?

MrMuchimi

Q = mcΔT = (4.00 g)(0.129 J/g•°C)(40.85 °C - 0.85 °C)
Q = 20.6 J of energy was involved (more specifically, 20.6 J of heat energy was absorbed from the surroundings by the sample of solid gold).

Describe the effects of anaerobic respiration on the body and explain the effects on the body

anzhelika [568]

Answer:

In anaerobic respiration, glucose breaks down without oxygen. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water. Unfortunately this can lead to painful muscle cramps.

The daily production of carbon dioxide from an 880 MW coal-fired power plant is estimated to be 31,000 tons. A proposal has been

miskamm [114]

Answer:

$1.3578\times 10^{8} m^3$ volume of carbon dioxide gas would be collected during a one-year period.

Explanation:

Mass of carbon dioxide gas collected in a day = 31,000 Tonn

1 Tonn = 1000 kilogram

31,000 Tonn = $31,000\times 1000 kg=31,000,000 kg$

Specific volume of the carbon dioxide gas = $V_s$

$V_s=0.012 m^3/kg$

Volume of carbon dioxide gas collected in a day = V

$V=V_s\times 31,000,000 kg=0.012 m^3/kg\times 31,000,000$

$V=372,000 m^3$

1 year = 365 days

Volume of carbon dioxide gas collected in a year = V'

$V'=372,000\times 365 m^3=1.3578\times 10^{8} m^3$

$1.3578\times 10^{8} m^3$ volume of carbon dioxide gas would be collected during a one-year period.

What is the main component of atoms that determines the type of bond that forms between atoms or compounds? Explain.

goldenfox [79]

I think There should be a valanced state in every atom. (Valanced state means, 8 electrons in the outer most orbit) In case take a atom has 8 electrons in the outer orbit, so when bonding the two atom to form a molecule, there is a Ionic Bond (because of both atoms has its own valanced electron(8 electrons in outer most orbit).
