To calculate the amount of heat evolved when 2 moles of methane that is burned, we use the value of the heat of combustion and multiply it by the number of moles. We calculate as follows:
Heat = 2 mol ( - 890 kJ/mol) = -1780 kJ -------> OPTION A
Answer:
yes
Explanation:
sodium is salt and you can get it in the store or anywere.
Answer:
2NaClO₄ (aq) + Ni(NO₃)₂ (aq) → 2NaNO₃ (aq) + Ni(ClO₄)₂ (aq)
No reaction
Explanation:
NaClO₄ → Sodium perchlorate
Ni(NO₃)₂ → Nickel (II) nitrate
All the salts from nitrate are soluble salts
All the salts from perchlorate are soluble salts except for the KClO₄
