2A + 3B--> A2B3 If 3mL of 0.04M A, 4mL of 0.02M B and 3mL of H2O was into a reaction test tube, what are the concentrations of A and B in the test tube.

Explanation:

Hello,

In this case, given the concentration and volume of each reactant, we first compute their moles in the solution:

Thus, since the total volume is computed given the volume of each reactant as well as the extra water, we have:

Thus, the concentrations of A and B are:

Best regards.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
