The answer is a because its not low ductile or gasst
Answer:
that will be endothermic reaction...... as oxides of mercury decomposes and break s into simpler elements by absorbing energy
Explanation:
hope it helped u buddy
Answer:
<u>89.6 L</u>
Explanation:
In normal conditions,
<u><em>For every </em></u><u><em>1 mole</em></u><u><em> of carbon dioxide at STP, it occupies </em></u><u><em>22.4 L</em></u><u><em> of volume.</em></u>
<u><em /></u>
============================================================
Solving :
⇒ 1 mole : 22.4 L
⇒ 1 × 4 : 22.4 × 4
⇒ 4 moles : <u>89.6 L</u>
Answer:
chemical reactions which proceed with the release of heat energy are called exothermic reactions
Explanation:
When heat is absorbed by reactants in a chemical reaction then the reaction is known as endothermic reaction.
Whereas when heat is released by reactants in a chemical reaction then the reaction is known as exothermic reaction.
1. When 
is positive then it means heat is absorbed by reactants and reaction is endothermic.
2. When 
, this means energy of products is less than the energy of reactants. Therefore, it is exothermic in nature.
3. When energy is absorbed then reaction is endothermic.
4. When 
, this means energy of products is greater than the energy of reactants. Therefore, it is endothermic in nature.
5. When [tex]\Delta H is negative then it means heat is released by reactants and reaction is exothermic.
