Correct answer=

gold is an element, it has a symbol of An

Hope it helped

Answer 2

Final answer:

Gold is an element, not a compound or a mixture. It is represented on the periodic table by the symbol Au and cannot be broken down into a simpler substance.


Gold is an element, not a compound or a mixture. It's one of the 118 known chemical elements, and it's represented on the periodic table by the symbol Au (from the Latin 'aurum'). As an element, gold consists of only one type of atom and cannot be broken down into a simpler substance. It differs from a compound, which is formed from two or more elements bonded together, and a mixture, where you can physically separate the individual components that make it up.

1a) Chemical inertness

1b) transparency

2) extremely less brittle

3) they can melt very easily under moderate heat.

4) they have low melting point

5) metals are hard, meaning they can easily injure a baby. Metals are good absorbers and radiators of heat.

6) they are less hard when compared to metals so they are less probable to cause injuries to kids.

7) material with very low density.

How can you increase the electrical output of a generator?Decrease the speed of the spinning magnet.
Increase the turns of the wire.
O Decrease the turns of the wire.
Decrease the speed of the spinning solenoid.
O Decrease the size of the magnet.​



Increase the turns of the wire


By increasing the number of turns the wire has made, you are increase the inductive power of the coil in the generator, thereby giving rise to the output of the generator.

Increase the turns of the wire.

A 50°C solution has a pH of 3.30. At this temperature, Kw = 5.48 x 10 9. What is the pOH of the solution?





Your value for Kw is incorrect. The correct value is 5.48 × 10^-14.

  pH + pOH = pKw

3.30 + pOH = -log(5.84 × 10^-14) = 13.23

          pOH = 13.23 - 3.30 = 9.93

The pOH of the solution is 9.93.

The pOH of the solution is 10 .

Given that, the pH of the solution is 3.30, we also know that;

pH = - log[H^+]


[H^+] = Antilog (-3.3)

[H^+] = 5.0 × 10^-4 M


Kw = [H^+] [OH^-]

[OH^-] = Kw/[H^+]

The accurate value of Kw is 5.48 × 10^-14 not  5.48 x 10 9

[OH^-] = 5.48 x 10^-14/ 5.0 × 10^-4

[OH^-] = 1.1 x 10^-10 M

pOH = - log[1.1 x 10^-10 M]

pOH = 10
