HELP!!!!!!PLZ!!!!!ASAP!!!!!

It is an open series circuit and this is why:
 
its obvious its a series circuit because all the symbols are in a straight rectangle.

Which best explains why blood is considered to be a suspension?
Stells [14]
I think the best answer is b): it contains particles that can settle out.

The definition of suspension is a heterogeneous (that is same in all parts) mixture that contains particles that could undergo sedimentation (settle down) - this definition is close to b). It should not matter whether those particles are nutrients( so A or C are not good answers).

Zns (zinc sulfide) (Zn = 65.38; S = 32.06] *
irakobra [83]

The question is incomplete, the complete question is;

Zinc and sulfur react to form zinc sulfide by the equation shown below. How many grams of ZnS can be formed when 12.0 g of Zn reacts with 6.50 g of S? (Atomic mass: Zn = 65.38, S = 32.06).

Answer:

17.5 g of ZNS

Explanation:

The equation of the reaction is;

Zn(s) + S(s) ------->ZnS(s)

Number of moles of Zn = 12.0/65.38 = 0.18 moles

Number of moles of S = 6.50/32.06 = 0.20 moles

Hence Zn is the limiting reactant

If 1 mole of Zn yields 1 mole of ZnS

Then 0.18 moles of Zn also yields 0.18 moles of ZnS

Mass of ZnS produced = 0.18 moles *  97.44 g/mol = 17.5 g of ZNS
