Answer:
endormic
Explanation:
It occurs at a temperature and pressures below a substance's triple point on its phase diagram, which corresponds to the lowest pressure at which the substance can exist as a liquid
It will double
Key
P = pressure of the gas
n= number of moles of the gas
V= volume of the gas
R = the gas constant
T= absolute temperature of the gas
If V is halved when n and T remain the same
Answer:
moles of H2O = 4.5 mol
Explanation:
balanced equation:
∴ mass SnO2 = 339 g
∴ molar mass SnO2 = 150.71 g/mol
⇒ moles SnO2 = (339 g)(mol/150.71 g) = 2.25 mol SnO2
⇒ moles H2O = (2.25 mol SnO2)(2 mol H2O/mol SnO2)
⇒ moles H2O = 4.5 mol H2O
Silver has one valence electron and oxygen has 6 electrons in the outermost shell. Ionic bonds are formed by the transfer of electrons from a metal to a non metal.
atoms are most stable when they complete their outermost shell and complete the octet. This is when their s and p subshells in the outermost shell are complete, eight electrons hence complete octet.
silver has one valence electron so to become stable it will lose that valence electron and transfer it to oxygen. Oxygen has 6 valence electrons so to become stable it needs 2 electrons to complete its octet.
One silver atom gives one electron each, since oxygen needs 2 electrons ,
2 silver atoms are needed to form an ionic bond.
Ag will become cation - Ag⁺ and Oxygen will become an anion - O²⁻
ionic bond is formed due to the electrostatic attraction between oppositely charged ions
ionic compound - Ag₂O
2 silver atoms needed for one oxygen
