Convection has convection is heat transferred from solid to gas
Explanation:
The given data is as follows.
= 1.5 atm, 
= 20 L, 
= (28 + 273) K = 301 K
= 5 atm, 
= ?, 
= (50 + 273) K = 323 K
Formula to calculate the volume will be as follows.
= 
Putting the given values into the above formula as follows.
=
= 
= 0.64 L
Thus, we can conclude that the change in volume of the balloon will be 0.64 L.
Answer:
The answer is A, It shows an exothermic overall reaction.
Explanation:
A maximum of 8 electrons can share the quantum number n = 2.
Principal Quantum number has a symbol of "n". It tells you the energy level on which an electron resides. Y<span>ou need to determine exactly how many </span>orbitals<span> you have in this energy level before you can determine the number of electrons that can share the value of n.
</span>
The number of orbitals you get per energy level can be found using this formula:
<span>no. of orbitals=<span>n</span></span><span>²</span>
Each orbital can hold a maximum of two electrons, the formula would be:
<span>no. of electrons=2<span>n</span></span><span>²</span>
Using the given formulas:
<span>no. of orbitals = <span>n</span></span><span>² </span><span>= </span><span>2</span><span>² </span><span>= </span><span>4</span>
<span>no. of electrons </span><span>=</span><span>2 *</span><span> </span><span>4 </span><span>= </span><span>8 </span>
<span>After 1 half-life, 1/2 the sample has decayed. After 2 half-lives 3/4 of the matter has decayed. So after, 3 half-lives about 11/12 would have decayed.</span>
