Answer : The correct option is, An egg cooking

Explanation :

  • Endothermic reaction : It is a type of chemical reaction in which the energy is absorbed from the surrounding.
  • Exothermic reaction : It is a type of chemical reaction in which the energy is released into the surrounding.

Water freezing  : It is an exothermic process. In this process, the heat is released when the phase changes from the liquid state to solid state.

An egg cooking  : It is an endothermic process. In this process, the heat is absorbed when the phase changes from the solid state to liquid state.

A candle burning : It is an exothermic process because the more amount of  heat is released when candle burns.

Iron rusting : It is an exothermic process because heat is released during the iron rusting process.

Hence, an egg cooking  is an endothermic reaction.

Just did the test.

Answer is "An egg cooking".

I thought it was a candle burning because it keeps going until the light goes out but was wrong :( lol.

Hope this helps!

Use the drop-down menus to classify each of the following as an addition, substitution, elimination, or
OLga [1]

Answer:

CH3CHO+H2O → CH3OCH3 - addition

CH,CICH CI + Zn → C2H4 + ZnCl2 - elimination

CH3CH3Br + OH – CH3CH3OH + Br - substitution

2CH2COOH >>(CH3CO)20 + H20 - condensation

Explanation:

An addition reaction is a reaction in which a specie is added across the double bond as we can see in CH3CHO+H2O → CH3OCH3.

In an elimination reaction, a small molecule is lost from a saturated compound to form the corresponding unsaturated compound as in CH,CICH CI + Zn → C2H4 + ZnCl2

In a substitution reaction, a chemical moiety replaces another in a molecule as in; CH3CH3Br + OH – CH3CH3OH + Br .

A condensation reaction is in which two molecules are joined together to form a bigger molecule as in; 2CH2COOH >>(CH3CO)20 + H20.

The equation for the synthesis of ammonia is below. How many moles of H 2 are
kkurt [141]

Moles of H₂ are needed to produce 9.33 moles of NH₃ : 13.995

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

The reaction coefficient in a chemical equation shows the mole ratio of the reactants and products

Reaction for the synthesis of ammonia :

N₂+3H₂⇒2NH₃

moles of NH₃ = 9.33

From equation, mol ratio of H₂ : NH₃ = 3 : 2, so mol H₂ :

\tt =\dfrac{3}{2}\times 9.33\\\\=13.995

shtirl [24]
Your answer is correct, I do not understand why it would be wrong.
The electron accepting tendency of an atom is known as the tendency of an atom to accept an electron. This is ranked on a scale of 0.7 to 3.98 and these species have the following values:
F: 3.98
O: 3.44
C: 2.55
Be: 1.57
Li: 0.98
