Explanation:
Intensive property: It is the property of substance which is independent of quantity of substance. Color of an ink is an intensive property.
Extensive property: It is the property of substance which depends upon quantity of substance which is just opposite to intensive property. Volume of an ink is an extensive property.
(2) The catalyst provides an alternate reaction pathway with a lower activation energy.
(3) The catalyst provides the same reaction pathway with a higher activation energy.
(4) The catalyst provides the same reaction pathway with a lower activation energy.
The correct answer is:
1.how electrons are organized in a cloud
2. why electrons are not attracted into the positively charged nucleus
3. variations in chem behavior between elements
Explanation:
Rutherford reversed Thomson's model in 1911 with his popular gold foil research in which he confirmed that the atom has a tiny and massive nucleus. Rutherford created an experiment to practice the alpha particles released by a radioactive element as probes to the underground world of atomic structure.
I won't give you the answer, but I will give you the process and then you can plug in the numbers. I'm guessing you are looking for how many MOLES are in 63.658g of Carbon. What you need to do to solve this is to use the molar mass of Carbon plugged into the dimensional analysis process. That might sound confusing, so let me give you a sample question.
Now, you plug in the numbers in your problem into that sample process. And if you don't know where to find the molar mass, it's simple.
The Molar mass of an element is the same as the atomic mass. So Hydrogen has the atomic mass of 1.01u, and it also has the molar mass of 1.01 grams per mole.
Answer: The limiting reagent is Oxygen molecule and 4 atoms of Iron will be left over.
Explanation:
The given chemical equation is:
By Stoichiometry of the reaction:
3 molecules of oxygen gas reacts with 4 atoms of iron.
So, 6 molecules of oxygen gas will react with = atoms of iron.
As, the required atoms of iron is less than the given atoms of iron. Therefore, it is present in excess and is considered as an excess reagent.
Hence, the limiting reagent is Iron atom because it limits the formation of product.
Atoms left remaining at the end of the reaction will be = 12 - 8 = 4 atoms.
Thus, the limiting reagent is Oxygen molecule and 4 atoms of Iron will be left over.
