13. When iron nad is put in to a beaker containing copper sulphate solution.
svetlana [45]

Answer:

A simple displacement reaction occurs when an iron nail is immersed to a beaker containing copper sulphate solution.

a)

Iron is more reactive than copper. As a result a displacement reaction will take place. The ferrous or Fe (II) irons will move to the solution. The copper ions (Cu II) will get deposited on the nail. This will cause the colour to change from blue to green.

b)

The equation can be written as:

Fe (s) + CuSO4 (aq) -> FeSO4 (aq) + Cu (s)

c)

A chemical change can be described as a change that causes a substance to change to another form. Hence, this reaction is a chemical change.

The position of the equilibrium for a system where K = 6.4 × 10 9 can be described as being favoring ________________
geniusboy [140]

Answer:

to the right (products side)

Explanation:

The equilibrium constant K describes the ratio between the concentration of products and reactants at equilibrium. For a general reaction:

a A + b B → c C + d D

The equilibrium constant expression is:

K = \frac{[C]^{c} [D]^{d}  }{[A]^{a} [B]^{b}  }

A low value of K indicates that the concentration of products (C and D) is low in relation with the concentration of reactants (A and B).

Conversely, a high value of K indicated that the concentration of products is high compared with the concentration of reactants.

Since K = 6.4 × 10⁹ is a high value, the concentration of products is higher than the concentration of reactants at equilibrium. Thus, the position of the equilibrium is favored to the right.

mariarad [96]

Answer:

3.82 × 10 ^-23 g

Explanation:

6.02 x 10^23atoms = 1 mole of sodium

1 atom = 1/(6.02 x 10^23) mole

mass = mole × molar mass

= 1/(6.02 x 10^23) × 23

= 3.82 × 10 ^-23 g
