112 Identifying Types of Reactions: For each reaction shown, determine whether it is a synthesis, decomposition, combustion, single replacement, or double replacement (precipitation) reaction. Then balance the equation.

___Cu(aq) + ___S ___Cu2S(s)
___Li +___O2 ___Li2O
___C8H18 + ___O2___CO2+ ___H2O
Pb(NO3)2+ __KI ___PbI2 + ___KNO3
___Al + ___ZnCl2 ___Zn + ___AlCl3
___Zr + ___N2 ___ZrN4
___C4H10+ ___O2___CO2+ ___H2O
___NaCl + F2 → NaF + Cl2
___BaCl2 + ___KF ___KCl + __BaF2
___CdO ___Cd + ___O2
___CsCl ___Cs + ___Cl2

The answer which is not a detail carson used to describe the pool in the cave at low tide is b.  hundreds of periwinkles browse the branches and roots of the trees. 

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero. 

The correct answer should be b let me know if i’m wrong
