Minerals physical characteristics are hardness,luster,the way it’s solid and chemical would be the way the color changes and it’s density
Molar mass methane ( CH₄) = 16.04 g/mol
number of moles:
mass CH₄ / molar mass
8.67 / 16.04 => 0.5405 moles
1 mole ------------------ 22.4 L ( at STP )
0.5405 moles --------- ??
0.5405 x 22.4 / 1 => 12.1072 L
hope this helps!
Answer:
610.3g
Explanation:
Zn:
m = 1.912
Zn : ZnI₂
1 : 1
1.912 : 1.912
ZnI₂:
m = 1.912 Mr = 65.4 + 2(126.9) = 319.2
mass = m×Mr:
mass = 1.912×319.2
mass = 610.3104 → 610.3g
I’m not sure about this I’m sorry but I can’t understand the language
