The answer is either band theory or covelent theory but I'm pretty sure it's covelent theory
<span>The
scientist thought that the atom was the smallest particle in the universe is
John Dalton. He established the atomic theory which
consists of five; elements are made of extremely small particles called atoms,
atoms of different element have different sizes, mass and physic – chemical
properties, atoms cannot be divided further, destroyed or created, atoms can
combine to form compounds and in chemical reaction, atoms can be combined,
separated or rearranged</span>
Answer:
ΔH = - 5315 kJ.
Explanation:
The given chemical reaction is as follows -
2C₄H₁₀ (g) + 13 O₂ (g) → 8 CO₂ (g) + 10 H₂O (g) + 5315 kJ
In the above equation , the amount of energy i.e. 5315 kJ is released , i.e. it is in the product side , hence , the reaction is an example of an exothermic reaction .
Hence ,
The value of the change in enthalphy , i.e. , the enthalpy of product minus the enthalpy of the product .
Therefore ,
The value of the change in enthalphy = - ve .
Hence ,
ΔH = - 5315 kJ.
Answer:
Other comparisons of the legislative process in both chambers shows that:
In both House and Senate: Committees review and mark up bills.
In the House of Representatives: Bills are introduced by the reading clerk.
In Senate: Bills can be filibustered.
In Senate: Only related amendments can be attached to bills.
In both House and Senate: Unrelated riders can be attached to bills.

Answer:
Depending on the 
value of 
, the cell potential would be:
, using data from this particular question; or- approximately
, using data from the CRC handbooks.
Explanation:
In this galvanic cell, the following two reactions are going on:
- The conversion between
and 
ions, 
, and - The conversion between
and 
ions, 
.
Note that the standard reduction potential of ions to is higher than that of ions to . Alternatively, consider the fact that in the metal activity series, copper is more reactive than silver. Either way, the reaction is this cell will be spontaneous (and will generate a positive EMF) only if ions are reduced while is oxidized.
Therefore:
- The reduction reaction at the cathode will be: . The standard cell potential of this reaction (according to this question) is
. According to the 2012 CRC handbook, that value will be approximately 
.
- The oxidation at the anode will be:
. According to this question, this reaction in the opposite direction () has an electrode potential of 
. When that reaction is inverted, the electrode potential will also be inverted. Therefore, 
.
The cell potential is the sum of the electrode potentials at the cathode and at the anode:
.
Using data from the 1985 and 2012 CRC Handbook:
.
