Answer:
Each Hydrogen atom has one only one electron which is also its valence electron and Sulfur has six valence electrons. Thus, there are a total of eight valence electrons in H2S. In this compound, both the hydrogen atoms require one electron to make the covalent bond with Sulfur
Answer:
mass of carbon = 0.438g
Explanation:
mass percentage = 0.00438%
Sodium, Salt, Gold, Platium
Answer: C) Heat
What I know so far is that heat makes it harder for the electrons to reach the source, thus making it hard to collide with the nucleus, but I’m not sure so you can see if it’s correct.
Answer:
b) Water boiling and mixing cola and root beer sodas are favorable processes, but assembling a house of cards is not.
Explanation:
Entropy, a measure of a system's thermal energy per unit of temperature that cannot be used to do work. Work, is obtained from directed motion of molecules, it follows the the amount of entropy is a measure of the molecular randomness, or disorder, of the system. As such increased entropy increases randomness hence water boiling and mixing cola and root beer sodas are favorable processes, but assembling a house of cards which requires a great deal of effort is not.
