The table shows the number of charged subatomic particles in an ion. Charged Particles:
Charge on Particle: Number of Particles:
Positive 12
Negative 10

A positively charged substance is brought near the ion. What will most likely happen and why?

A - The ion will attract the substance because it has lost two electrons.
B - The ion will attract the substance because it has lost an electron.
C - The ion will repel the substance because it has lost two electrons.
D - The ion will repel the substance because it has lost an electron.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
