Caesium is the most reactive. It is found in the far corner of the periodic table, a<span>nd it is the most reactive metal in the entire thing. It is even more reactive than Francium. This is a radioactive element and it decays. </span>Caesium<span> is more reactive than this, so those would be the top two. I don't know the third most reactive though sorry... 

I hope this helped! :)</span>

Hydrogen atoms fuse together to form helium atoms. This releases a huge amount of energy in the form of _______ and ______. (cal
WARRIOR [948]

Answer:

Hydrogen atoms fuse together to form helium atoms. This releases a huge amount of energy in the form of Kinetic energy of the alpha particle and Electromagnetic radiation.

Explanation:

Nuclear Fusion is the Nuclear process in which the energy is produced when two lighter elements are collided together which are having some kinetic energy in them after that the two lighter nuclei will fuse together into a single heavier nuclei. This is opposite to what happens in Fission process in which the breaking up of atomic specie happens.

Both Nuclear Fission and Nuclear fission occurs with the release of massive amount of energy.

There are conditions for nuclear fusion to happens like, it requires 100 million's kelvin of temperature, also fusion will occur when the pressure is very high because increased pressure will result into squeezing of the atomic specie and hence they will fuse.

When the Hydrogen atom fuse together to form helium atoms. This release a huge amount of energy in the form of Kinetic energy of the alpha particle and Electromagnetic radiation.

What happens to the ions when the drain is turned off? please help :] ❤️
kkurt [141]

Answer:

In a long channel MOSFET, the width of the pinch-off region is assumed small relative to the length of the channel. Thus, neither the length nor the voltage across the inversion layer change beyond the pinch-off, resulting in a drain current independent of drain bias. Consequently, the drain current saturates.

22.4 liters of a gas at a constant temperature of zero Celsius and a pressure of 1 atmosphere is compressed to a volume of 6.2 l
zhannawk [14.2K]
<h2>Hello!</h2>

The answer is: The new pressure of the gas is 3.6 atm.

<h2>Why?</h2>

From the statement we know that the gas is kept at a constant temperature of 0°C, so, if the gas keeps a constant temperature we can use the Boyle's Law to solve this problem.

The Boyle's Law states that:

P_{1}V_{1}=P_{2}V_{2}

Where,  

P is the pressure of the gas.

V is the volume of the gas.

So, the given information is:

V_{1}=22.4L\\P_{1}=1atm\\V_{2}=6.2L

Now, substituting it into the Boyle's Law equation to calculate the new pressure, we have:

P_{1}V_{1}=P_{2}V_{2}\\\\1atm*22.4L=P_{2}*6.2L\\\\P_{2}=\frac{1atm*22.4L}{6.2L}=3.6atm

So, the new pressure is 3.6 atm.

Have a nice day!
