Hi!
The answer to this is true.
Hope it helps! :)
Sulfur is an element in the periodic table that has a chemical symbol of S. This element is the 16th element in periodic table. This means that the atomic number or number of protons in the nucleus of the atom is equal to 16.
The number following the name of the element is the mass number. The following are the complete symbol that are arranged as follows:
chemical symbol - atomic number - mass number
*Sulfur-32
S - 16 - 32
*Sulfur-33
S - 16 - 33
*Sulfur-34
S - 16 - 34
142 g ---------------- 6.02 x 10²³ molecules
0.920g g ------------ ( molecules )
molecules = 0.920 x ( 6.02 x 10²³ ) / 142
molecules = 5.53 x 10²³ / 142
= 3.89 x 10²¹ molecules
1 molecule P2O5 -------------------------- 7 atoms
3.89 x 10²¹ molecules -------------------- ( atoms )
atoms = ( 3.89 x 10²¹) x 7 / 1
atoms = <span>2.72 x 10²² atoms of P2O5
Hope this helps!!!

Answer:
Chemical equilibrium is also called as dynamic equilibrium because it in chemical equilibrium, the equilibrium can shift towards both sides that is reactant and product known as equilibrium shifting. And in chemical equilibrium, the reaction is going on but the rate of formation of reaction is equals to the rate of formation of product.
Hope this helps!
Answer:
Cell division is the process by which a cell, called the parent cell, divides into two cells, called daughter cells.[1] When the cell divides, everything inside it divides also. The nucleus and the chromosomes divide, and the mitochondria divide also.
In mitosis, an ordinary body (somatic) cell divides to make two daughter cells.
In meiosis, a cell divides twice, to produce four gametes (sex cells). The first division of meiosis is a special kind of cell division called a reduction division because the number of chromosomes is halved. The second division of meiosis is similar to mitosis.[2]
Three types of cell division: left is binary fission as in bacteria; right are mitosis and meiosis as in eukaryotes.
Cells are the 'building blocks' of life, and cell division is a basic feature of life. For simple unicellular organisms like Amoebozoa, one cell division reproduces the entire organism. On a larger scale, cell division can create offspring from multicellular organisms, such as plants that grow from cuttings. But most importantly, cell division enables organisms that are able to sexually reproduce to develop from the one-celled fertilised egg (zygote). Cell division also allows for continual renewal and repair of the organism.
