2H₃PO₄ + 3Ca(OH)₂→ 6H₂O + Ca₃(PO₄)₂
Answer:
Explanation:
When naming molecular compounds prefixes are used to dictate the number of a given element present in the compound. ” mono-” indicates one, “di-” indicates two, “tri-” is three, “tetra-” is four, “penta-” is five, and “hexa-” is six, “hepta-” is seven, “octo-” is eight, “nona-” is nine, and “deca” is ten.
Answer is: more H⁺ ions than OH⁻ ions.
<span>An Arrhenius acid is a
substance that dissociates in water to form hydrogen ions or
protons.
For example, hydrochloric acid dissociate in aqueous
solution to form hydrogen ions (H</span>⁺)
and chloride anion (Cl⁻):<span>
HCl(aq) → H</span>⁺(aq) + Cl⁻<span>(aq).
</span>
An Arrhenius base is a
substance that dissociates in water to form hydroxide ions (OH⁻<span>).
For example lithium hydroxide is an Arrhenius base:</span>
LiOH(aq) → Li⁺(aq) + OH⁻(aq).
Answer:
Chromosomes help ensure that DNA is replicated and distributed appropriately during cell division.
Explanation:
The industrial synthesis of ammonia is spontaneous.
to to prove this one calculate the gibbs free energy(delta G)
= delta G = Delta H -T delta s
delta H = -92.2 kj in joules -92.2 x1000 =-92200j
delta s = -199j/k
T= 25+273= 298k
delta G is therefore= -92200-298(-199)=-32898j
since delta G is negative the reaction is therefore spontaneous
