Answer:
P2O3
Explanation:
Firstly, we know that the phosphorus would absorb oxygen from air to form its oxide. We already know the mass of the phosphorus, we can get the mass of the oxygen by subtracting the mass of the phosphorus from the mass of the oxide.
The mass of the oxygen is 2.57 - 1.45 = 1.12g
From here, we covert these masses to moles by dividing by the atomic masses of phosphorus and oxygen respectively.
The atomic mass of phosphorus is 31 while that of oxygen is 16.
P = 1.45/31 = 0.046774193548
O = 1.12/16 = 0.07
We now divide by the smallest which is that of phosphorus.
P = 0.046774193548/ 0.046774193548= 1
O = 0.07/ 0.046774193548 = 1.5
We then multiply the answers by 2 for conversion to whole numbers. Making P = 2 and O = 3
The empirical formula is thus P2O3
The chemical breakdown of enormous quantities of organic material buried in the sedimentary rocks has produced ethane gas.
Answer: at higher temperatures.
Justification:
1) Soda have CO₂ dissolved. Carbonation consists on that: dissolving CO₂ into water, leading to carbonated water.
2) The solution of a gas into a liquid is inversely related to the temperature: the lower the temperature the more gas gets dissolved.
So, in the manufacturing of soda, the CO₂ is added in cool water in a cool environment.
3) So, the higher the temperature after the soda is delivered, the more gas will be liberated when you open the can.
WHAT IS AN IONIC BOND
kossel explained that inert gases r inert due to the electronic configuration which contains 8 electrons in their outermost shell
And other elements loss and gain electrons to form ions and to have electronic configuration same as Noble gas and to get stable
