Answer:
Explanation:
An object decreases in size due to the collision of materials. An object increases in size due to the addition of materials. Gas particles are formed from solar nebula materials.
It must absorb energy in the form of for example heat which gives it the energy required to become excited
hope that helps
Answer:
P₂O₄
Explanation:
From the question given above, the following data were obtained:
Empirical formula = PO₂
Molar mass of compound = 126 g/mol
Molecular formula =.?
The molecular formula of the compound can be obtained as illustrated below:
Molecular formula = [Empirical]ₙ
= molar mass
[PO₂] × n = 126
[31 + (16× 2)] × n = 126
[31 + 32] × n = 126
63 × n = 126
Divide both side by 63
n = 126 / 63
n = 2
Molecular formula = [PO₂]ₙ
Molecular formula = [PO₂]₂
Molecular formula = P₂O₄
Answer:
2 differet atoms.
Explanation:
Molecule: group of two or more atoms held together by chemical bonds. So, minimum 2 atoms are required to form a molecule.
