Explanation:

Metals and non-metals can be identified either by their position in the periodic table or by their properties.

he metal elements are found on the left hand side of the periodic table, and the non-metal elements are found on the right. You can imagine a zig-zag line, starting at B-Al-Si, separating metals from non-metals.

Suppose 0.981 g of iron (II) iodide is dissolved in 150. mL of a 35.0 m M aqueous solution of silver nitrate. Calculate the fina
yaroslaw [1]

Answer:

Final molarity of iodide ion C(I-) = 0.0143M

Explanation:

n = (m(FeI(2)))/(M(FeI(2))

Molar mass of FeI(3) = 55.85+(127 x 2) = 309.85g/mol

So n = 0.981/309.85 = 0.0031 mol

V(solution) = 150mL = 0.15L

C(AgNO3) = 35mM = 0.035M = 0.035m/L

n(AgNO3) = C(AgNO3) x V(solution)

= 0.035 x 0.15 = 0.00525 mol

(AgNO3) + FeI(3) = AgI(3) + FeNO3

So, n(FeI(3)) excess = 0.00525 - 0.0031 = 0.00215mol

C(I-) = C(FeI(3)) = [n(FeI(3)) excess]/ [V(solution)] = 0.00215/0.15 = 0.0143mol/L or 0.0143M

two sides of a triangle have the following measures . Find The range of possible measures for the tird side
crimeas [40]
To find the third side you would use Pythagorean theorem which is a²+b²=c². 

A and B being the 2 legs and C being the hypotenuse.
 
Example: ( sorry for the really odd not really a triangle, triangle...)
  |  \
6|     \  ?                    6²+9²=C²
  |_______              36+81=C²
        9                             117=C²
                               √117=10.8 (rounded) 

if you need to get the leg you just fill in the numbers.
