Answer:
the properties of catalyst are
it remains unchanged after chemical reactions
it accelerate or deaccelerate the reaction without taking part in it
Explanation:
they are used to convert raw materials into useful one
catalyst are integral in making plastics
Answer:
the standard cell potential value
Explanation:
For every cell, we can calculate its standard electrode potential from the table of standard electrode potentials listed in many textbooks.
However, from Nernst's equation;
Ecell= E°cell - 0.0592/n log Q
Hence the standard cell potential (E°cell) affects the value of the calculated cell potential Ecell from Nernst's equation as stated above.
Explanation:
What is true about an atom in an excited state? Select all that apply:
A. It is less likely to enter chemical reactions.
B. It is more likely to enter chemical reactions.
C. It has less energy than a ground state atom.
D. It has more energy than a ground state atom.
Explanation:
the correct match can as follows:
1. helium ⇒ discrete atoms (helium is an inert gas)
2. oxygen ⇒ molecules (oxygen exists in molecular form as O2)
3 Magnesium ⇒ matalic lattice ( Magnesium is a metal FCC crystal Structure :) )
4 Aluminum⇒ covalent network (since it is situated in the middle of the group and posses amphoteric properties too)
