X₂O₃ ===> 3 moles of oxygen == > 48 g O
Molar mass of X₂O₃-------------- 48g O
30,6g --------------------------------- 14,4g
Molar mass = (30,6×48)/14,4
Molar mass = 102g
Molar mass of X₂ = 102 - 48 = 54g
Molar mass of X = 54/2 = 27g
X ==> 27 g/mol ==> Al
X₂O₃ ==> Al₂O₃

it's C. but the sentence is incorrect I think it should be a ball "in" someone's hand
Explanation:
cause potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.
Id say true, as if it exceeds the flow capasity there would be to much water flowing,therefor causing a flood
Musculoskeletal system because the mussels help move your bones.
Answer:

Explanation:
Range = Highest value - Lowest value
A 'soft solder' melts between 183 °C and 212 °C.
Melting range of a 'soft solder' = 
A 'hard solder' melts between 620 °C and 680 °C.
Melting range of a 'hard solder' = 
So,
Difference in melting ranges = Melting range of a 'hard solder' - Melting range of a 'soft solder' =
