Explanation:
w is the stage in which dna is copied and cell grows.
The average atomic mass of Sn is 118.71 g/mol
the percentage of heaviest Sn is 5.80%
the given mass of Sn is 82g
The total moles of Sn will be = mass / atomic mass = 82/118.71=0.691
Total atoms of Sn in 82g = ![6.023X10^{23}X0.691=4.16X10^{23}](https://tex.z-dn.net/?f=6.023X10%5E%7B23%7DX0.691%3D4.16X10%5E%7B23%7D)
the percentage of heaviest Sn is 5.80%
So the total atoms of
= 5.80% X ![4.16X10^{23}](https://tex.z-dn.net/?f=4.16X10%5E%7B23%7D)
Total atoms of
=
atoms
the mass of
will be = ![\frac{2.41X10^{22}X124}{6.023X10^{23}}=4.96g](https://tex.z-dn.net/?f=%5Cfrac%7B2.41X10%5E%7B22%7DX124%7D%7B6.023X10%5E%7B23%7D%7D%3D4.96g)
You have a raw egg you put it in a hot pan boom cooked egg most chemical changes are nonreversibal <span />
Answer:
--Acid is the substance when dissolved in water, increases the concentration of H+ ions.
--Such compound whose chemical formula begins with H, for example HCl (Hydrochloric acid), H3BO3 (Boric acid), CH2O3 (Carbonic
acid). Although CH3COOH (Acetic acid) is an exception.
--Its less than 7.
--Bases are the proton acceptor.
--Such compounds whose chemical formula ends with OH, for example KOH (Potassium hydroxide), NaOH (Sodium hydroxide).
--Its greater than 7.
