Make an observation.
Ask a question.
Form a hypothesis, or testable explanation.
Make a prediction based on the hypothesis.
Test the prediction.
Iterate: use the results to make new hypotheses or predictions. Hope this helps
Answer:
29.8 mg
Explanation:
Just slightly less than 1/2 decay
Explanation:
The dissociation constant of the water is given as :
The value of st 25°C =
Water is neutral in nature with equal amount of hydronium and hydroxide ions.
The pH of the water at 25°C is 7.
With increase in temperature dissociation of water will increase with which concentration of hydronium and hydroxide ions will also increase which will in return will lower the down the pH of the water at higher temperature.
Answer:
The correct answer is: <em>They each partially describe the bonding in a molecule.</em>
Explanation:
Some chemical molecules cannot be described completely by using only one Lewis structure. In these cases, we can describe the molecule by drawing 2 or more Lewis structures, and the structures are called <u>resonance structures</u>. The overall molecular structure is explained by all the resonance structures together. So, they each describe the bonding in the molecule only partially.
I think the answer would be A because O is oxygen and it has 7. Although it’s in parentheses and has a 2 on the outside of those parentheses, so you would multiply and 7 x 2 = 14. 14 is larger than the other ones.
Hopefully I’m right and hopefully that helps.
