Answer:
Explanation:
Looking at the atom, you see that there is 1 carbon atom and 2 oxygen atoms.
The chemical formula of Carbon is just C (from the periodic table), and the chemical formula of Oxygen is just O (from the periodic table).
When you create the chemical formula of a compound, you want to indicate how many atoms of each element there are. Here, since there are 2 oxygen atoms, you want to have some form of 
, and since there's only 1 carbon atom, you want to have some form of C.
Now, we just put it together: (this is btw carbon dioxide)
Hope this helps!
We generally represent an element by its symbol. provided with the atomic number and mass number or atomic mass
Atomic number is the number of protons present in an element. It is constant for an element.
The mass number of element is the sum of number of protons and number of neutrons
The atomic mass is the total mass of all the protons and neutrons present in the element (in its nucleus).
the number of electrons is equal to number of protons in a neutral atom of element.
The mass of electrons is not included in the total atomic mass of element as it is very low.
So here
12 = it is the number of protons = atomic number of element.
The true statements are
The combined mass of protons and neutrons is 24.305
Answer:
1.1grams
Explanation:
Find moles of water:
4.5x10^22/(6.02x10^23)=0.07mol
Find molar mass of the water
O=16.00g/mol
0.07x 16.00=1.1 grams
Hello Norgepr, examples of failed experiments that produced valuable information
can be the mage via BoingBoing
There have been ample stories of human children being raised by other
species and eventually becoming more like that animal than an actual
human. If the process could go one way, Winthrop Kellogg was sure that
it could also go the other, particularly if the animal involved was one
of our closest genetic cousins. In 1931, Kellogg received a grant for
his experiment and the timing couldn’t be better –his wife just had a
baby boy, David. This would give them the unique opportunity to raise a
baby chimp, named Gua, right along side a human baby. It didn’t take
long for the babes to bond and become best friends. Kellogg and his
wife took impeccable notes on their two “children” noting their physical
changes, emotions and how they scored on small intelligence tests. The
chimp scored notably higher on the intelligence tests due the fact that
the species matures faster than human babies. Gua picked up quite a few
human behaviors, such as walking upright and eating with a spoon, but
she failed to learn how to speak and learn simple repetition games, like
patty cake. Her emotions were also much less predictable and inclined
to change at the drop of a hat. Unfortunately, the experiment really
started to go wrong when little David started to become more chimplike
than Gua became humanlike. He only learned a few simple words and often
took to making chimp howls when he wanted something. After only nine
months, the Kelloggs gave up on Gua, concerned that David would fail to
grow up like a normal human child. In the years since this project,
plenty of people have adopted chimps as babies, proving beyond a doubt
that the animals can never act completely human –even if they are
adorable in overalls.
