Answer:
The value of N would be 4.
Explanation:
The equation would be 2n^x = 32 and therefore, 4.
Moles of P = 56,4g/30,974g/mole = 1,82 moles P
moles of O = 43,6/15,999 = 2,73 moles of O
converting to the simplest ratio:
For P : 1,82/1,82 = 1
For O : 2,73/1,82 = 1,5
1 P and 2 oxygens.
PO2 -> the empirical formula
hope this help
Camouflage is an adaptation because you change yourself for better survival.
For example, an Octopus can change the color of its body to blend in with its surroundings which makes it hard for predators and prey to see them.
Hello!
BeH₂ is a linear molecule, while CaH₂ is an angular molecule.
The difference between these two molecules is given by the number of electrons they have. Be is in the 2nd period of the Periodic table, and the ion Be⁺² doesn't have any free electron pairs when bonding to H. Ca is in the 4 period of the periodic table, meaning that it has more electrons, and the ion Ca⁺² has two free electron pairs when bonding to H that makes the molecule angular by pushing the bonds at an angle by sterical hindrance.
Have a nice day!
Answer:
(i) Cl₂ is a limiting reactant
(ii) The amount of excess reactant = 4.8 g
Explanation:
Br₂(g) + Cl₂(g) → 2 BrCl(g) ---------------------------(i)
Calculation of no. of moles
Using mole ratio method to find the limiting reactant and Excess reactant.
So 
is a limiting reactant and Br₂ is excess reactant.
The amount of excess reactant = 0.18 - 0.15 = 0.03 mole = 4.8 g
