Answer:
Attraction
(e-) ---> <--- (H+)
Repulsion:
<---(e-) (e-)-->
Neutral:
(e-) (Helium)
Explanation:
Accordingly to coulomb's law:
In the attraction, the hydrogen without an electron has a positive charge and needs to be fulfilled with a negative charge found in an eletron.
In the repulsion, both electrons has the same charge and repulse each other.
In the neutral case, the Helium is highly stable therefore the electron is not attracted.
The final temperature = -145.24K or 127°C.
According to the data given,
T1= 88°C = 361.15K
V1= 9.6 L
V2= 3.4 L
T2= ?
We know that, according to Charles's law,
T1/V1=T2/V2
T2= T1*V2/V1
T2= 127°C or -145.24K
The final temperature = -145.24K or 127°C
<h3>What does Charles law state?</h3>
According to Charles' law, when the pressure is held constant, the volume of a given amount of gas is precisely proportional to its temperature on the kelvin scale.
<h3>What connection exists between volume and temperature?</h3>
- In layman's words, the volume of a fixed mass of gas is exactly proportional to temperature at constant pressure.
- When a constant mass of gas is cooled, its volume decreases, and when the temperature is elevated, its volume grows.
<h3>What are the applications of Charles law?</h3>
- A hot air balloon drifting through the air is an illustration of Charles Law in action.
- The air within the balloon is heated by a torch, which causes the air molecules to move more quickly and disperse.
- This causes the air inside the balloon to be less dense than the air outside, which causes the balloon to float.

Answer:
answer is b
Explanation:
All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor
Answer : The final temperature of the mixture is 
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of iron = 
= specific heat of water = 
= mass of iron = 39.9 g
= mass of water = 
= final temperature of mixture = ?
= initial temperature of iron = 
= initial temperature of water = 
Now put all the given values in the above formula, we get
Therefore, the final temperature of the mixture is
