Mitosis has one round of cellular division and genetic separation whereas meiosis has two rounds. The two processes are also different because in mitosis the daughter cells are exactly identical to the parent cells compared to meiosis where the daughter cells are not genetically identical to the parent cells
Hope this helped
1. Is charge 2. Is the first one
Alkali Metals (Group 1) elements experience an increase in the vigour of their reaction in water as they go down the group (as the atomic number increase). As such the most reactive Alkali Metal would be
FRANCIUM, which is at the base of Group One.
Quite frankly, you do not want Francium to react with water- that's a huge explosion on your hand.
Answer:
one mole of oxygen will produce
moles of water
Explanation:
The balanced chemical reaction is as follows -
2 C2H2 + 5 O2 --> 4 CO2 + 2 H2O
As we can see in this reaction
5 mole of oxygen (on the reactant side) will produce 2 mole of water (on the product side)
Hence, one mole of oxygen will produce
moles of water
Mendeleev created the first periodic table by ordering the elements by atomic mass, rather than their atomic numbers.
