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
HOPE IT HELPED
I can't answer the question without the statements but I can tell you Calorimetry means measuring amounts of heat released or received during a chemical reaction.
Answer: 3.13 g
Explanation:
Radioactive decay follows first order kinetics.
Half-life of uranium-232 = 68.8 years
N = amount left after time t
= initial amount
= rate constant
t= time
= 100 g, t= 344 years, 
N=3.13g
Answer:
atom 2 and 3 or d is should be your answer
Explanation:
.....
Answer:
ALL ISOTOPES OF AN ELEMENT HAVE THE SAME NUMBER OF;
1. PROTON
2. ATOMIC NUMBER
Explanation:
Isotopes are atoms with the same atomic number but different mass numbers. Isotopes of an element has the same number of proton which dictates the atomic number of the atoms. The difference in mass number is as a result of the difference in the number of neutrons. Isotopes of an atom have different physical properties but they exhibits the same chemical properties because neutrons have no influence on the chemical properties and the change or difference in neutrons will produce no effect on the chemical properties of the atoms. Neutrons only contributes to the mass of the atoms giving the isotopes of an atom different mass numbers. An example is chlorine with two isotopes, Cl -35 and Cl -37.
Properties Cl-35 Cl-37
mass number 35 37
atomic number 17 17
number of protons 17 17
number of electrons 17 17
number of neutrons 35-17 = 18 37-17 = 20
abundance in nature 75% 25%
