Answer:
this is very easy to solve
- (NH4)2 Co3,(NH4)2 So4,( NH4)3 Po4
- k2 co3, k2 so4,k3 Po4
- zn oh2, zn (No3)2, zn3 (Po4)
- ca oh2
- fe oh3, fe(No3)3, fe2 (co3)3, fe2 (so4)3
this is a answer I am very sure
This means that neutral zinc atom has a total of 30 electrons surrounding its nucleus. To see how many of these electrons are valence electrons, write the electron configuration of a neutral zinc atom. Notice that the outermost shell, which for zinc is the fourth shell, n=4, has two electrons. Hope this helps. :)
Answer:This condensation is needed to allow the chromosomes to move along the mitotic spindle without becoming tangled or broken during their distribution to daughter cells. DNA in this highly condensed state can no longer be transcribed, so all RNA synthesis stops during mitosis.

An oil separates crude oil into its components by distillation. some components are altered <u>by cracking and Reforming.</u>
<u />
The crude oil contains many petroleum products like petrol , diesel , Mobil oil coaltar and many more with impurities So, now it is very important to separated it into components to use all product individually in pure form.
The separation process are based on fraction distillation because all petroleum products have different density and boiling points. All products are separated at different temperature.
