Answer:
circuit
electric current
voltage difference
ohms law
resistance
Explanation:
Circuit - a roughly circular line, route, or movement that starts and finishes at the same place.
Electric current - A net unidirectional movement of electrons, or other charge carriers, caused by a potential difference
Voltage difference - A potential difference of one Volt is equal to one Joule of energy being used by one Coulomb of charge when it flows between two points in a circuit.
Ohms law -a law stating that electric current is proportional to voltage and inversely proportional to resistance.
Resistance - The refusal to accept or comply with something; the attempt to prevent something by action or argument.
The reason why perchloric acid is more acidic that ethane is because the hydrogen in perchloric acid is bonded to oxygen which is more electronegative than carbon.
The acidity of a substance depends largely on the ease with which the X-H bond is broken. If the electron density is tilted towards the atom X, then the X-H bond is weaker and the substance is more acidic.
The polarity of the X-Y bond depends on the electronegativity of X. In the case of perchloric acid and ethane, oxygen is more electronegative than carbon hence the O-H bond in perchloric acid is more easily broken than the C-H bond in ethane.

When the enthalpy change of the reaction is positive, the reaction is exothermic.
Chemical weathering is when things get weathered chemically
Answer:
1 mol of water is produced in those conditions.
Explanation:
The reaction to produce water between H₂ and O₂ is this:
2H₂ + O₂ → 2H₂O
We don't have the amount of hydrogen, so we have to think that is in excess.
Let's work with oxygen.
Ratio is 1:2
For 0.5 mole of oxygen, I will make the double of moles of water.
