Answer:
Ag₂CrO₄(s) + H⁺(aq) ⟶ 2Ag⁺(aq) + HCrO₄⁻(aq)
Explanation:
Ag₂CrO₄(s) ⇌ 2Ag⁺(aq) + CrO₄²⁻(aq).
Silver chromate is the salt of a strong base (AgOH) and a weak acid (H₂CrO₄).
HCrO₄⁻ is an even weaker acid than H₂CrO₄, so CrO₄²⁻ is a strong base.
Any added H⁺ will immediately combine with the chromate ions according to the reaction
H⁺ + CrO₄²⁻ ⟶ HCrO₄⁻
thereby removing chromate ions from solution.
According to Le Châtelier's Principle, more silver chromate will dissolve to replace the chromate ions that the H⁺ removes.
The overall equation for the reaction is
Ag₂CrO₄(s) ⇌ 2Ag⁺(aq) + <em>CrO₄²⁻(aq)
</em>
<u>H⁺(aq) + </u><em><u>CrO₄²⁻(aq)</u></em><u> ⟶ HCrO₄⁻(aq)
</u>
Ag₂CrO₄(s) + H⁺(aq) ⟶ 2Ag⁺(aq) + HCrO₄⁻(aq)
Answer:
it means that things people come up with can be tested and they can turn it into the truth or in another sense figure out if its true or not
Explanation:they can figure out if its real or not and or turn it into the facts from what people make up and or think so and so is this or that and they can find out the truth
Answer:
a.substitution
Explanation:
because one of the hydrogen atoms from the methane is replaced with a bromine atom.Alkanes undergo a substitution reaction with halogens in the presence of light. For example, in ultraviolet light , methane reacts with halogen molecules such as chlorine and bromine. This is a substitution reaction because one of the hydrogen atoms from the methane is replaced by a bromine atom.
Answer:
The more reactive the metal, the more rapid the reaction is. A metal below hydrogen in the reactivity series will not react with dilute acids.
Explanation:
Cr(NO3)3
because Chromium (III) formula is Cr2O3 And Nitrate formula is NO3
