The orbital is the probable location of the electron of an atom.
Always remember the difference between Bohr and wave-mechanical model in terms of electrons!
Your questions answer is Electron!
But you should also know Bohr said electrons are in orbitals in a fixed proportion, but modern wave mechanical disagrees with this and said electrons are arranged in a very complex random proportion in a region called orbital!
Hope this helped
have a smiley day (:
Answer:
D
Explanation:
Al is a reducing agent because it removes Oxygen from another compound
Mno2 is an oxidizing agent
Question: Given the balanced equation representing a reaction:
2H2 + O2 ==>2H2O
What is the total mass of water formed when 8 grams of hydrogen reacts completely with 64 grams of oxygen?
(1) 18 g (3) 56 g
(2) 36 g (4) 72 g
Answer:
"72 gram" is the total mass of water formed when 8 grams of hydrogen reacts completely with 64 grams of oxygen
Explanation:
We will do stoichiometry in this kind of problem:
Therefore, the total mass of water formed is 72 g.
Answer: Option D
Explanation:
Chemotrophs can be defined as the organism which has the ability to get energy by the oxidation of electron donors present in the nearby environments.
These molecules in the environment can be organic or inorganic.These bacteria are usually called as thiobacillus denitrificans.
These bacteria reduce the nitrate into nitrite and the energy source for these bacteria is thiosulfate(sulfur).
Answer:
1) adding ice
2) adding heat
3) altering amount of water
4) using a different kind of cocoa mix
Explanation:
Dissolution of a substance in another can be affected by temperature changes, concentration and the type of mix we are using.
The higher the temperature, the more readily a compound will dissolve in another. The rate of dissolution of a solute in a solvent is affected by prevailing temperature at hand.
The more the water which is the solvent, the more the solute that can be dissolved in it. Reaction rate is directly proportional to concentration.
A different cocoa mix might dissolve better in this case also.
