It could be Ne(Neon) or Ar(Argon) but the difference between both of them is that they are in different period Neon is in the 2 period and Argon is in 3 period
Answer:
D 1.0 g of powdered Zn(s) in 50. mL of 1.0 M HCl(aq) at 30.°C
Explanation:
There are several factors affecting and controlling the rate of chemical reactions.
Some of which are applicable in resolving this problem is the nature of the reactants and their concentration. Also, the temperature of the reaction is also very important.
- Reactants that powdered ensures a faster rate because, more surface area is exposed for the reaction.
- Also, the higher the temperature, the faster the reaction will take place.
- So, the powdered zinc and the higher temperature reaction will facilitate a better rate of reaction.
Answer:
Explanation:
Phenolphthalein is a protonated indicator and methyl orange is a basic indicator having hydroxyl ionisable part .
Phenolphthalein can be represented by the following formula
HPh which ionizes in water as follows
HPh + H₂O ⇄ H₃O⁺ + Ph⁻
( colourless ) ( pink )
In acidic solution it is in the form of protonated Hph form which is colourless
In basic medium , it ionises to give H₃O⁺ and unprotonated Ph⁻ whose colour is pink .
