Answer:
The atomic mass is the average number of protons and neutrons for all natural isotopes of an element. It is a decimal number.
Explanation:
Atomic Mass and Mass Number Example
:
Hydrogen has three natural isotopes: 1H, 2H, and 3H. Each isotope has a different mass number.
1H has 1 proton. Its mass number is 1. 2H has 1 proton and 1 neutron. Its mass number is 2. 3H has 1 proton and 2 neutrons. Its mass number is 3. 99.98% of all hydrogen is 1H 0.018% of all hydrogen is 2H 0.002% of all hydrogen is 3H Together, they give a value of atomic mass of hydrogen equal to 1.0079 g/mol.
Answer:
It is called a reduction-oxidation, oxide-reduction reaction, or simply as a redox reaction, any chemical reaction in which one or more electrons are transferred between the reactants
Redox battery is an example of both a Flow Battery and a two electrolyte system.In this case, it depends on two different active aqueous electrolytes of vanadium dissolved in sulfuric acid separated by a membrane at which ionic interchange takes place.
Thats my opinión though.
Answer:
Significant hydrogen bonding is possible in 
Explanation:
- Hydrogen bonding takes place between an electronegative atom (O, N and F) and a H atom attached to those electronegative atoms.
- Lewis structure reveals that H atom attached to N in .
- In all other compounds no such H atom is present attached to O or N or F.
- Hence significant hydrogen bonding is possible only in
- Lewis structures are given below.
Answer:
Explanation:
3NO₂ + H₂O → 2HNO₃ + NO
n/mol: 12.66
You get 1 mol of NO from 3 mol of NO₂
