I believe it would be better to use an orbital designation than the written configuration, if the number of electrons in the ground state of the atom are quite high for the given element, as above 50, for instance.
This saves space and also one can see the discrete quantized energy levels associated with the subshells of the main energy levels if written in orbital designation.
1) C !! Physical Process
2) A
3) D !! Water is universal solvent !
if you need any explanation ; comment !!
Kinetic energy maybe or something
Answer: 50 grams
Explanation: The water is still only going to be 50 grams. Although it’s in a different state, it didn’t gain or lose any water while being frozen.
Answer:
The correct answer is a catalyst.
Explanation:
Catalysts are substances that can be added to a reaction to increase the reaction rate without being consumed in the process.
They generally work by reducing the energy of the transition state and thus decreasing the activation energy or changing the mechanism of the reaction. This also changes the nature (and energy) of the transition state. Biochemical processes, such as glucose oxidation, rely heavily on enzymes, proteins that act as catalysts.
Other common types of catalysts are acid-base catalysts and heterogeneous or surface catalysts.
Have a nice day!
