Answer:
calcium to give calcium oxide to give calcium trioxocabonate (limestone) to give carbondioxide
Answer: This is simple, if it has a high flammability, and you light it on fire, then that would be a chemical change.
Explanation:
May i have brainliest please and don't forget to drop a heart
Answer:
high less air cause there is no trees and lower is the same
Explanation:
This indicates that the reaction is exothermic meaning that it releases heat/energy
First let us determine the electronic configuration of
Bromine (Br). This is written as:
Br = [Ar] 3d10 4s2 4p5
Then we must recall that the greatest effective nuclear
charge (also referred to as shielding) greatly increases as distance of the
orbital to the nucleus also increases. So therefore the electron in the
farthest shell will experience the greatest nuclear charge hence the answer is:
<span>4p orbital</span>
