The answer is b since oxygen has 6 valence electrons.
A full understanding of the physical processes which lead to different types of auroras is still incomplete, but the basic cause involves the interaction of the solar wind<span> with the Earth’s magnetosphere. The varying intensity of the solar wind produces effects of different magnitudes, but includes one or more of the following physical scenarios. so the answer is A</span>
If the strength of the base and acid is EXACTLY the same/equal, the result would be: A. a neutral solution
That is why we used a base based medicine to treat our acid reflux because it will bring back the condition of our stomach into its neutral state
hope this helps
Spectator ions are the ions on the right side of the equation which do not combine to form products.
You have a typo in your formula (looks like a .jpg pic link you tried to paste), but we can see that potassium ions (K+) and bromine ions (Br-) appear unreacted on both sides of the equation. Therefore, the correct answer is C) K+ and Br-
Additionally, we know from solubility rules that Group 1 ions (including potassium, K, remain soluble in aqueous systems, meaning they do not combine with other ions and form products.
