Answer:
It decreases.
Explanation:
Due to changes in the Coulombic force, the protons within the nucleus of the ion have a much easier time pulling at one fewer electrons. This way, the electrons are pulled closer to the center, causing the radius to decrease.
Answer:
shiny
Explanation:
because metals surface are berkilau
I am not going to do your work for you. However, just a reminder that a science experiment must be able to yield the same results if done in the same conditions by another scientist.
Answer:
386.45 K
Explanation:
We can solve this problem by using <em>Charles' law</em>, which states that at constant pressure:
Where subscript 1 stands for initial conditions of volume and temperature, while 2 stands for the final ones. Meaning that in this case:
- T₁ = 36 °C ⇒ 36 +273.16 = 309.16 K
We<u> input the data</u>:
- 2.0 L * T₂ = 2.5 L * 309.16 K
And <u>solve for T₂</u>:
Answer:
Meteorologists use computer models to predict the weather. And computational power has come an extended way. Yet meteorologists still have trouble correctly predicting the weather over some days. Sometimes they don’t even comprehend right over 24 hours! Why does this happen? Their ability to predict the weather is restricted by the number of available data, the time available to research it, and therefore the complexity of weather events.
