The answer is Strontium Nitride
Answer:
The coefficient in a balanced chemical equation indicates the mole ratio of both reactants and products.
Explanation:
For example lets consider the reation between Hydrogen and Oxygen to form water:
2H2 + O2 ----------------------- 2H2O
In this reaction, the coefficients of the balanced reaction can be transformed to Mole ratio according to Avogadro's Law which states that at standard temperature and pressure, equal volume of gases contain the same number of moles.
So the mole ratio for the above equation is the ratio of the coefficient:
2moles : 1 mole : 2 moles
So you would just take the coefficient and put it into ratio form
Answers:
1) 4:5
2)4:6
3)6:4
4)6:6
5)6:4
Lead have:
82 electrons
82 protons
125 neutrons
Explanation:
The number of electrons and protons are given by the atomic number of the element.
Lead have 82 electrons and 82 protons.
The number of neutrons are given by the difference between the mass number and atomic number.
For lead number of neutrons = 207 - 82 = 125.
