Nuclear power plants can release hurtful chemicals into the environment while fossil fuel can be as efficient and less harmful to your surroundings.
The question is incomplete; the complete question is;
In the early 1900s many scientists thought that an atom consisted of a positive substance with negative charges scattered throughout the substance. Then Ernest Rutherford completed an experiment that changed the concept of an atom. His discovery led to the understanding that an atom consists mostly of empty with space with-
Protons orbiting a dense nucleus made of electrons and neutrons
Electrons orbiting a dense nucleus made of protons and neutrons
Neutrons and protons orbiting a cloud of electrons
Electrons and protons orbiting a cloud of neutrons
Answer:
Electrons orbiting a dense nucleus made of protons and neutrons
Explanation:
Rutherford established the nuclear theory of the atom by his famous experiment. In his experiment, alpha particles were used to bombard a thin gold foil and the movement of the particles was observed on a moveable zinc sulphide screen.
It was discovered from the experiment that the atom was mostly made up of empty space. The electrons orbit a dense nucleus comprising of protons and neutrons.
<u>Answer:</u>
A. Solution of copper (II) sulfate reacts with solution of sodium hydroxide to produce "copper hydroxide & solution of sodium sulphate".
B. Solid baking soda (sodium hydrogen carbonate or sodium bicarbonate) reacts with solution of hydrochloric acid to produce "carbon dioxide and water".
<u>Explanation:</u>
When CuSO4 is an acid salt while NaOH is a solid base mixed together. This reaction results into a basic copper hydroxide in the form of pale blue precipitate & sodium sulphate, which is a solution of neutral salt. This process is called as both a double displacement and precipitation reaction.
2NaOH + CuSO4 --> Cu(OH)2 + Na2SO4.
Sodium bicarbonate is used as a cleaner, from a "primitive" material to extract any acidic contaminants, for producing a nobler sample. Sodium bicarbonate and acid mixture generates a salt and carbonic acid that breaks down readily into carbon dioxide and water.
NaHCO3 + HCl → NaCl + H2CO. H2CO3 → H2O + CO2(g).
Answer:
How do you find pressure given moles volume and temperature?
Therefore, to convert the moles of gas to pressure, the scientist must know the volume and temperature of the gas, in addition to the number of moles of gas. The pressure is then given by P = nRT / V.
I very much Disagree. The esophagus runs from your mouth to your stomach.
