An unscientific device for locating oil or minerals; a divining rod.
The bond that are broken from the reaction would be ionic bonds. Calcium oxide and hydrochloric acid are held by ionic bonds so that these are also the bonds being broken and are being formed as well. Hope this answers the question.
Answer:
Six electrons are transferred in the formation of Al₂O₃.
Explanation:
Aluminium metal and Oxygen react to form Al₂O₃ as,
2 Al + 3/2 O₂ → Al₂O₃
Oxidation number of Al on left hand side is zero, while than on right hand side in Al₂O₃ is +3. Means it has lost 3 electrons per one atom and six electrons per two atoms. Also, the oxidation number of O at left hand side in O₂ is zero, while that in Al₂O₃ it is -2 per atom and -6 per 3 atoms.
So, two Al atoms have lost 6 electrons and 3 O atoms have gained six electrons.
Answer:
(c) temperature
Explanation:
In a closed system, as the temperature increases, the molecules in the liquid are exited and converts into gas. The more the gas transformed, the more the gas(vapor) pressure. The less the gas transformed, the less the vapor pressure.
Therefore, temperature is a major factor in vapor pressure.
