WINSTONCH [101]3 years ago
3 0

Answer:

b  energy is being released from the atoms

Explanation:

Seeing light from fireworks implies that energy is being released from the atoms. This is an excitation as the electrons within the atom moves from a higher energy level to a lower energy level.

  • When electrons undergo this kind of transition, energy is released.
  • The radiation produced is dispersed out and it is seen as colorful lights.
  • Most times such processes are exothermic

Nutka1998 [239]

Answer:

D. Reduction takes place at the cathode, which is negatively charged.

Explanation:

In an electrolytic cell there are two electrodes; the cathode and the anode. The anode is the positive electrode while the cathode is the negative electrode. Oxidation occurs at the anode while reduction occurs at the cathode.

At the anode, species give up electrons and become positively charged ions while at the cathode species accept electrons and become reduced.

William adds two values, following the rules for using significant figures in computations. He should write the sum of these two
Alinara [238K]
It seems that you have missed the necessary options for us to answer this question, but anyway here is the answer. William adds two values, following the rules for using significant figures in computations. He should write the sum of these two numbers by using the same number of decimal places as the least precise value. Hope this helps.
