"As the molecules in a sample move faster the temperature reading will be lower" is not true.
This is the Lewis structure for NH3.
Answer:
285.6
Explanation:
(283.4×0.3460)+(284.7×0.2120)+(287.8×0.4420)
=285.6204
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
<span>We know that an ideal gas keeps the relation between pressure, volume and temperature constant.
P * V / T = constant
Then if we have the gas in two diferente state:
P1*V1/T1 = P2*V2/T2
Temperature remain constant so then:
P1*V1 = P2*V2
98.5*285 = 94.2*V2
V2 = 98.5*285/94.2 = 298 ml
So the volume of the ammonia will be 298 ml</span>
