<span>0.333 ounce * 0.75 * 28.35 grams/ounce = 7.080 grams gold
7.080 grams Au / 196.967g/mol Au = 0.0359 mol Au
0.0359 mol Au * (6.023 * 10^23) atoms/mol = 2.24 * 10^22 Atoms Au</span>
<span>When a sound wave reaches near the ear, the outer part of the ear acts like if its a funnel, so it catches the wave and funnels it into the ear. They the wave hits the eardrum. Then the bones in the eardrum cause each other to vibrate. Then they are sensed by nerves and sends signals to the brain to interpret sound. Hope This Helps!</span>
The equilibrium expression shows the ratio
between products and reactants. This expression is equal to the concentration
of the products raised to its coefficient divided by the concentration of the
reactants raised to its coefficient. The correct equilibrium expression for the
given reaction is:<span>
<span>H2CO3(aq) + H2O(l)
= H3O+(aq) + HCO3-1(aq)
Kc = [HCO3-1] [H3O+] / [H2O] [H2CO3]</span></span>
Answer: In factories they burn coal under a giant container(a really big gumbo pot pretty much). when the fire is hot enough it starts to boil. When it boils it creates steam and the steam blows on a fan that makes electricity.
The materials which allow heat to pass through them easily are conductors of heat. For examples,aluminum, iron, and copper.
Hope this helps! ;)
