What is the mole ratio of d to a in the generic chemical reaction? 2a+b—c+3d

The mole ratio from D to A is 3:1:1:2.

Explanation:

Chemical reaction:

A + B → C + D

Balanced chemical equation

2A + B → C + 3D

This general reaction shows that two mole of reactant A and one mole of reactant B react to form one mole of product C and three mole of product D.

Coefficient with reactants and products:

A  2

B  1

C  1

D 3

thus the mole ratio from D to A is 3:1:1:2.

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
