Answer:

The temperature of the reaction mixture increases.

Explanation:

One very good indicator that a chemical reaction has taken place is that there is a temperature change about the reaction.

Either an emission of heat involving the reaction milieu becoming hotter or an absorption of heat making the environment colder.

Enthalpy changes of reactions are good parameters to measure whether or not a reaction has taken place.
There is no color change, and mass is always conserved for most reaction, so we cannot use these tools for assessing whether a reaction has occurred or not.

Dmitriy789 [7]

Answer:

H₂SO₄ (aq) + H₂O (l) → HSO₄⁻ (aq) + H₃O⁺ (aq)

HSO₄⁻ (aq) + H₂O (l) ⇄ SO₄⁻²(aq) + H₃O⁺ (aq) Ka

Explanation:

The sulfuric acid is a dyprotic acid.

It is a considered a strong acid but only the first deprotonation is strong.

Second deprotonation is totally weak

That's why we have equilibrium when it release the second proton.

Since a deprotonation is treated for a weak acid, the acid is considered not to completely dissociate, that's why the equilibrium

What is the Electronegativity of sugar

lyudmila [28]

Answer:In order for a molecule to have polarity it must have an electronegativity difference of 0.5-1.7. There is polarity within sucrose because of oxygen-hydrogen and oxygen-carbon. Oxygen-hydrogen is polar because a electronegativity of 1.2 is created (O=3.4 H=2.2-----> 3.4-2.2=1.2); this is a polar molecule.

The question is incomplete, here is the complete question:

Nickel and carbon monoxide react to form nickel carbonyl, like this:

$Ni(s)+4CO(g)\rightarrow Ni(CO)_4(g)$

At a certain temperature, a chemist finds that a 2.6 L reaction vessel containing a mixture of nickel, carbon monoxide, and nickel carbonyl at equilibrium has the following composition:

Compound Amount

Ni 12.7 g

CO 1.98 g

$Ni(CO)_4$ 0.597 g
