How do you know if a reaction is endothermic?

Chemistry
1 answer:
Vikentia [17]3 years ago
6 0
In an exothermic reaction, heat is produced along with products. But in endothermic reaction, heat is absorbed. If the number of products is less than the sum of the enthalpies of the reactants, the reaction will be exothermic. If the number of products is more than the sum of the enthalpies of the reactants, the reaction is endothermic.

Now moles: _(1, 2, or 3)_moles of H2 + _(1, 2, or 3)_ moles of O2 → _(1, 2, or 3)_moles of H2O
arsen [322]

Answer:

2H₂ + O₂ → 2H₂O.

Explanation:

  • For the reaction of water formation:

<em>2H₂ + O₂ → 2H₂O.</em>

  • It should apply the the law of conservation of mass that the no. of reactants atoms is equal to the no. of products atoms.

<em>So, every </em><em>2.0 moles of H₂ </em><em>react with </em><em>1.0 mole of O₂</em><em> to produce </em><em>2.0 moles of H₂O.</em>

What does the group number of element 114 have to do with its stability?
zhenek [66]

Answer:

Super-heavy elements like 114 usually only exist for fractions of a second. ... The physicists called these magic numbers the “island of stability”, because the elements with the numbers cluster together on the periodic table, flanked on all sides by ephemeral elements that dissipate in nanoseconds.

Which is the correct Lewis structure for carbon monoxide?
LuckyWell [14K]
<span>The Lewis structure for CO has 10 valence electrons. For the CO Lewis structure you'll need a triple bond between the Carbon and Oxygen atoms in order to satisfy the octets of each atom while still using the 10 valence electrons available for the CO molecule.</span>
