<h2><u>Answer:</u></h2>
A nonpartisan iota of Nitrogen has a mass of 18. There are 7 protons in the core of this iota. What number of neutrons, complete electrons, and valence electrons are available
Nitrogen 15 has a nuclear mass of 15. The mass number is # protons in addition to # of neutrons, so for N-15 mass is 15 and the protons are dependably 7 so there must be 15-7=8 neutrons. N-15 has 7 electrons since it has 7 protons and p = e.
1 mole of NH42SO4 contains 42 moles of H. We take the 42 moles of H and multiply that times Avogadro's number (6.02x10^23) and get 2.5284x10^25 atoms of hydrogen

A. molecule is created when two of more atoms are chemically bonded .
pH of 1 is Red
pH of 13 is Yellow
Explanation:
Indicators are substances which change color to signal the end of an acid-base reaction as required by the balanced chemical equation of the reaction.
Examples are:
- methyl orange
- methyl red
- phenolphthalein
- litmus
- cresol red
- cresol green
- alizarin R3
For methyl red:
pH 1 is acidic and its red
pH 13 is basic and it is yellow
pH 7 is neutral and it is orange
