Answer:
A. 3.7 x 10⁻³
Explanation:
In the beginning of the reaction there are 0.200 moles of reactant. After 25 minutes, remain 0.108 moles. That means the moles that wer descomposed are:
0.200 moles - 0.108 moles = 0.092 moles of reactant were descomposed.
That descomposition occurs in 25 minutes. The average rate of descomposition in moles / minute are:
0.092 moles Methyl isonitrile / 25 minutes = 3.7x10⁻³ mol/min.
Right option is:
<h3>A. 3.7 x 10⁻³</h3>
Answer:
Your answer is ATOM
Explanation:
Atoms consist of a nucleus made of protons and neutrons orbited by electrons. Atoms are the basic units of matter and the defining structure of elements.
Basically, they are the building block of life because everything made of matter has atoms
The correct answer to this question is option A.
Answer:
A. the total number of valence electrons an atom has.
Explanation:
The columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties.
