7.20594 x 10^20
First you must determine how many moles of P3O5 you have. This is done by using the formula
Number of moles (n) = mass in grams of substance (m) /divided by/ Molar mass (M) [this is the sum of the atomic mass of all atoms in the compound]
n = 0.170 / P (31 x 2) + O (16 x 5)
n = 0.170 / 142
n = 0.001197 moles
Then you use avagadros number 6.02 x10^23 this is the number of atoms in one mole of any substance. Since you have 0.001197 moles you multiply the number of moles by avagadros number
0.001197 x (6.02 x 10^23)
= 7.20594 x 10^20 atoms
Answer:
Electrons can flow from one atom to another
Explanation:
Fundamentally, opposite charges attract each other, while same charges repel each other. This implies that protons, positively charged species, would repel each other, while electrons, negatively charged species, would also repel each other.
There would be an attraction force between protons and electrons, on the other hand.
Metals tend to lose their electrons to non-metals to form positively charged ions, also known as cations. Non-metals gain these electrons to become negatively charged anions.
The answer is: dinitrogen triphosphide. This is because Tri means 3 and there are 3 phosphates, Di= 2 and there are 2 nitrogen’s.
Total change in energy = Heat produced by system + work done on the system
= 228 - 55
= 173 kJ
Because this energy is released as heat, the reaction is exothermic.
