8. 4 grams of water will be produced.
The answer is B Nitrogen atoms will form three covalent bonds (also called triple covalent) between two atoms of nitrogen because each nitrogen atom needs three electrons to fill its outermost shell. Another example of a nonpolar covalent bond is found in the methane (CH4) molecule.
Answer:
Anode:
3Mg(s) ----------> 3Mg2+(aq) + 6e
Cathode:
2Al3+(aq) +6e ---------> 2Al(s)
Explanation:
Anode:
3Mg(s) ----------> 3Mg2+(aq) + 6e
Cathode:
2Al3+(aq) +6e ---------> 2Al(s)
Magnesium is more electro positive than aluminum hence it functions as the anode. Six electrons are lost/gained in the redox process as shown in the oxidation and reduction half reaction equations above. Magnesium is oxidized to magnesium ion while aluminum is reduced to elemental aluminum.
The only coefficient is a 2 behind the reactant hydrochloride.
Water has the highest latent heat of vaporization of any known liquid. it is true.
The quantity of energy required to turn a portion of a liquid substance into a gas has been known as the enthalpy of vaporization, commonly referred to as the evaporation process or heat of evaporation. The pressure where the transformation occurs determines the enthalpy of vaporization.
The highest known temperature at which water vaporizes. The heat of vaporization is the amount of energy required to vaporize 1 g of a liquid without causing the liquid's temperature to go up.
Therefore, the given statement is true.
