Matter is everything around you, atoms and molecules are all composed of matter.
<span>Body fossils can mostly be found in things like rocks and minerals deep in the ground or in mountains and caves. They can also be found in quick drying substances such as for example tar pits or basically anywhere where there has been historically chance of encountering a fossil. You can also find them in peat, so that's 4 then.</span>
Answer:
6.022 x 10²³
Explanation:
Data Given:
mass of carbon = 12.01 g
individual particles = 6.02 x 10²³
number of atoms = ?
Solution:
Formula used to find the number of atoms
no. of moles = number of atoms / 6.022 x 10²³ . . . . . (1)
So, first we have to find number of moles
Formula to find no. of moles
no. of moles = mass in grams/ molar mass. . . . . (2)
molar mass of Carbon = 12.01 g/mol
Put values in eq.2
no. of moles = 12.01 g / 12.01 g/mol
no. of moles = 1 mol
Now put the values in eq. 1
no. of moles = number of atoms / 6.022 x 10²³ . . . . . (1)
1 mol = number of atoms / 6.022 x 10²³
Rearrange the above equation
number of atoms = 1 mol x 6.022 x 10²³
number of atoms = 6.022 x 10²³
So it is 6.022 x 10²³ atoms in 12.01 grams of carbon. This 6.022 x 10²³ also Known as Avogadro's number that is one mole of any substance consists this number of atoms.

hope I helped
I think it means the reaction doesn't have any intermediate phases - the order doesn't change, and it moves at the same rate, it doesn't speed up or slow down at any time
