Answer:
Explanation:
The fission reaction taking place given in the question is:
The mass is conserved in the reaction.
So,
235 + 1 = A + 94 + 3×1
A = 139 g/mol
Also, number o protons remain same. So,
92 = Z + 36
Z = 56
The isotopic symbol is
Answer:
Single-celled organisms use cell division as their method of reproduction. Cell Division and Growth: A sea urchin begins life as a single cell that (a) divides to form two cells, visible by scanning electron microscopy.
Explanation:
Los organismos unicelulares utilizan la división celular como método de reproducción. División y crecimiento celular: un erizo de mar comienza su vida como una sola célula que (a) se divide para formar dos células, visibles mediante microscopía electrónica de barrido.

Explanation:
An atom with four electrons in its valence shell is capable of forming:
single bonds and atom with the described characteristics, can form 4 single bonds or a combination of single bonds and double or triple bonds. Ex alkanes
double bonds this atom can form one double bond and two single bonds or two double bonds. Ex alkenes
triple bonds this atom can form one triple bond and one single bond, Ex alkynes.
