Which reactant ion gives white precipitate with AgNO3 and light red when treated first with HCL then KSCN?

My guess is Fe2+ as FeSCN3+ is light red at least. Not sure, but I guess you'd use the HCL for oxidizing the iron to Fe3+

What is the reactant called that gets used up first?
The Limiting Reactant is the reactant that runs out first in a reaction.
How many mL of .117M AgNO3 solution would be required to react exactly with 3.82 moles of NaCl?
Balanced equation first! AgNO3 + NaCl -> AgCl + NaNO3 all one to one, get moles AgNO3 3.82 moles NaCl (1 mole AgNO3/1 mole NaCl) = 3.82 moles AgNO3 ------------------------------- Molarity = moles of solute/Liters of solution 0.117 M AgNO3 = 3.82 moles AgNO3/Liters Liters = 3.82/0.117 = 32.6 Liters which is 32600 milliliters which is unreasonable; check answer if you can
What is the definetions of limiting reactant in chemistery?
In a chemical reaction the limiting reactant is the reactant that there is the least of in the reaction; it determines the amount of product formed. In a chemical reaction it is the reactant that gets completely "used up"
Which is the limiting reactant when masses of reactants are same?
You must first convert the mass of each reactant into moles of each reactant. Having the same mass does not mean that the amount of each reactant is the same, because each reactant has its own unique molar mass. Refer to the related link below for instructions on determining limiting reactants, also called limiting reagents.
What ion causes white precipitate to form when treated with silver nitrate?
When a substance/ solution containing chlorine ions is added with acidified silver nitrate (i.e. adding nitric acid to silver nitrate first), a yellow, insoluble ppt in formed.

What is a reactant that runs out first in a reaction called?
The Limiting Reactant is the reactant that runs out first in a reaction.
What is the reactant that runs first out in a reaction called?
The Limiting Reactant is the reactant that runs out first in a reaction.
If you double a concentration of a reactant then the rate of the reaction doubled The order with respect to the reactant is?
First order; the rate is directly proportional to the concentration of reactant.

What comes first cloud formation or precipatation?
Cloud formation because clouds must form first before they precipitate. Precipitate happens when the clouds are too heavy, so clouds form first before they precipitate. :D
What is the first chemical in the chemical equation called?
The first reactant.

Which type of particle will settle to the bottom first?
The precipitate.

What is limiting reactant and how control the amount of product formed?
The limiting reactant is that reactant in a chemical reaction that will be used up first. Put another way, it is the reactant that is in the smallest supply. The way it controls the amount of product formed is that once it is used up, no more product can be formed, so the amount of product formed ultimately depends on the amount of the limiting reactant.
For each of the following precipitation reactions calculate how many grams of the first reactant are necessary to completely react with 56.5 g of the second reactant?
12.1g/moles
