Which organic compound is correctly matched with the subunit that composes it?
Alex787 [66]
It is the Starch-glucose. Glucose is a solitary sugar particle that your body can retain specifically in the digestive system. Sucrose and starches are starches shaped by at least two sugars reinforced together. The sugars in sucrose and starch must be separated into glucose particles in the gastrointestinal tract before your digestive organs can assimilate them.

Why are the elements 57 through 71 and 89 through 102, found separately at the bottom of the table?
Dovator [93]
Elements from 57 to 71 are Lanthanoids and from 89 to 103 are Actinoids. Simply I would say Actinoids have less similarity in chemical properties than Lanthanoids. On the other hands, Actinoids have randomized chemical strutural bonds.

Pb (NO3)2 (aq)+KCl (aq) Express answer as a chemical equation enter if reaction if no reaction occurs identify all phases
enot [183]

Answer:

Pb (NO₃)₂(aq) + 2KCl(aq)     →   2KNO₃(aq)    +  PbCl₂(s)

Explanation:

In given chemical equation the aqueous lead (II) nitrate react with aqueous potassium chloride and form aqueous potassium nitrate and lead chloride.

Chemical equation:

Pb (NO₃)₂(aq) + KCl(aq)     →   KNO₃(aq)    +  PbCl₂(s)

Balanced chemical equation:

Pb (NO₃)₂(aq) + 2KCl(aq)     →   2KNO₃(aq)    +  PbCl₂(s)

ionic equation:

Pb²⁺ (aq) + 2NO₃⁻ (aq) + 2K⁺(aq)  +  2Cl⁻ (aq)    →     2NO₃⁻(aq)  + 2K⁺(aq)  +  PbCl₂(s)

Net ionic equation:

Pb²⁺ (aq) +  2Cl⁻ (aq)    →   PbCl₂(s)

The NO₃⁻(aq) and  K⁺(aq) are spectator ions that's why these are not written in net ionic equation. The PbCl₂ can not be splitted into ions because it is present in solid form.

Spectator ions:

These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
