Areaction is endothermic and has an increase in enthalpy.
the answer would be 2mg+> 2mgo+energy
false i hope this is right
the correct answer is option d, that is low growing.
silene acualis (moss campion) refers to a small mountain wildflower, which thrives at the high arctic and tundra region, and in the higher mountains of north america and eurasia. moss campion is a low, ground-hugging plant. the tundra plants like moss campion exhibit unique adaptations to survive in the extreme conditions. these plants are small with small leaves, and with buds inserted within the foliage for supreme protection.
answer : the number of moles of is, 4.225 moles
solution : given,
moles of fe = 6 moles
moles of = 8.45 moles
the given balanced chemical reaction is,
by stoichiometry, we conclude that
1 mole of fe reacts with 2 moles of
so, 6 moles of fe will react with = of
from this we conclude that is considered as a limiting reagent and fe is the excess reagent.
by stoichiometry of the given reaction :
2 moles of produces 1 mole of
so, 8.45 moles of will produce = of
therefore, the number of moles of is, 4.225 moles
