What happens to the copper atoms of the penny in gold penny lab?
basically, the zinc electrons in the NaOH solution coat the copper penny and then when you wave it over a Bunsen burner, the two metals form an alloy (a homogeneous mixture with two or more elements) and make brass, not gold.
Are there more Bromine -79 or more bromine -80 atoms on earth?
There are more bromine-79 atoms on Earth than bromine-80 atoms. Bromine-79 is the most abundant isotope of bromine, making up over 50% of natural bromine, while bromine-80 is a much rarer isotope.
Is there more atoms in a glass of water than there is people in the world?
A small 100 ml glass of water has something like 10^25 atoms in it. That number is greater than the number of people who have ever existed on the planet, past and present. In fact there are more atoms in a glass of water than there are grains of sand on the earth.
What happens to a penny if it's heated?
When a penny is heated, its atoms absorb energy and start moving more rapidly, causing the penny to expand. This expansion can be visible as the penny gets slightly larger. If heated too much, the penny can also change color due to oxidation.
How many dozens of copper atoms in a penny?
A US 1 cent piece prior to 1982 was made of copper and had a mass of about 3.1g. This is about 0.049 moles of copper, or around 2.9 x 1022 atoms. More recent pennies are mostly zinc (97.5%) and have a mass of about 2.5g. This works out to around 2.2 x 1022 zinc atoms and 5.9 x 1020 copper atoms, so overall around 2.3 x 1022 atoms.

What falls to earth faster an apple or penny?
An apple falls faster than a penny. The penny's flat surface creates more wind resistance than the round apple. And as Galileo observed, it depends on wind resistance, not weight.

Where can one find penny trading stocks?
Penny trading stocks can be found on a number of websites online. Global Penny Stock is one of the more well known options for people interesting in this form of stocks.
How do the copper atoms in a penny stick together?
Metallic bonding - the metal atoms share their valence, or "outer" electrons. The electrons of many nuclei situate themselves between positively charged nuclei. Two or more nuclei are then attracted to the same valence electrons, causing them to "stick together" as a solid piece of metal.
