Answer: (1) Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei.
(2) Rates of chemical reactions are influenced by temperature and catalysts. Rates of nuclear reactions are unaffected by such factors.
(3) Nuclear reactions are independent of the chemical form of the element.
A chemical reaction is the process by which a CHANGE takes place (?)
Answer:
1.88 M
Explanation:
The following data were obtained from the question:
Mole of NaCl = 0.47 mole
Volume of solution = 0.25L
Molarity =?
Molarity is defined as the mole of solute per unit litre of the solution. It can represented mathematically as:
Molarity = mole /Volume
Using the above formula, the molarity of the salt water solution can be obtained as follow:
Molarity = 0.47/0.25
Molarity = 1.88 M
1. base
2. neutral
3. acid
4. base
If this is what you meant, hope it helps
Plasma is the phase of matter where particles at extremely high temperatures became ionized. The phase of matter is the composition of matter which depends on temperature. Plasma is the hot ionized gas consisting of approximately equal numbers of positively charge ions and negatively charged electrons.
