Condensation is the term used to describe the reaction
Answer:
Answer:
Explanation:
(A) Heavier members of group 1A are usually more reactive than the lighter members e.g. lithium react very slowly with liquid bromine whereas CS react violently.
Similarly Be of group 2A has smaller size, heavier member of this group show different colour in flame test but Be and Mg emit light when heated. Reactivity of group 2A metals decreases down the group
(B) In ethylene polymerization, the stronger catalytic action is shown by the alkyl of metal having less diameter e.g Be, Li etc.
A lithium alkyl in a hydrocarbon solvent is stereospecific catalyst for polymerisation of isoprene
Answer:
There are two questions here;
1. How many moles of tungsten atoms are there in 9.6*10^25 atoms of bromine?
This question is invalid as it is quite impossible to obtain the number of moles of tungsten atoms in another element, bromine. The question would have been written as the number of moles of tungsten atoms in 9.6*10^25 atoms of tungsten or bromine as the case may be.
To solve for the number of moles of an atom; we should recur that
I mole of an atom = 6.02*10^23 atoms
6.02*10^23 atoms = 1 mole
9.6*10^25 atoms = (9.6 *10^25 / 6.02*10^23) moles
= 1.595 *10^2 moles
2. The reaction of 9 moles of O2 will produce -------- moles of H2O in the combustion reaction of propane.
C3H8 + 5O2 -------> 3CO2 + 4H2O
5 moles of O2 produces 4 moles of H2O
9 moles of O2 will produce (9 * 4/ 5) moles of H2O
= 7.2 moles of H2O
9moles of O2 will produce 7.2 moles of H2O.
