Answer:
Listed below
Explanation:
Analytical chemistry: using quality and quantity observations to identify and measure physical and chemical properties of substances.EXAMPLE: medical diagnosis
Physical chemistry: Combination of physics and chemistry. EXAMPLE:nitric acid eating through wood.
Organic chemistry: Studying of compounds containing carbon in them. EXAMPLE: there are different products that make use of this type of chemistry for example perfumes,gasoline and many more.
Inorganic chemistry: Studies materials without carbon i them. EXAMPLE: Metals AND Gases.
Biochemistry: studies chemical processes occurring in living organisms. EXAMPLE: Human bodies and muscles
Theoretical chemistry: provides explanations to chemical and physical observation. EXAMPLE: Concepts of chemical reactions

Explanation:
Hello!
In this case, according to the reaction:
We can see there is a 4:2 mole ratio between chromium and chromium (III) oxide, this, for the given 56.2 g of chromium, the theoretical yield of the oxide product is computed down below:
Now, considering the 76.0-% yield for this reaction, the actual yield turns out:
Best regards!
The correct conditions for measuring reduction potentials (the tendency to acquire electrons and become reduced), is 25C and 1M (or 1 mole/litre) for reactants - ANSWER B.
Answer:
It's too far away
Explanation:
According to classical mechanics, gravitational pull is inversely proportional to the distance squared; as the distance increases, the gravitational pull decreases at a faster and faster rate. Since Alpha Centauri A is a few lightyears (Tens of trillions of kilometers away), without even needing to calculate the force of gravity, it is very miniscule.
Answer:
Stoichiometric Coefficients
The balanced equation makes it possible to convert information about one reactant or product to quantitative data about another element. Understanding this is essential to solving stoichiometric problems
