The type of energies or the words in this item
are matched with the given descriptions. The lists below are as follow.<span>
<span>a. The word that best match this description is MECHANICAL
energy. In most sources, mechanical energy is described to be that
energy that is possessed by an object with respect to its motion and position. </span>
<span>b. The answer to this item is LIGHT energy. This type
of energy can be created through different means (i.e. radiation, chemical, and
mechanical). This is the energy emitted by hot objects such as the sun, lasers,
and bulbs.</span>
<span>c. The type of energy that is transferred by the movement of
the electrons through a conductor is ELECTRICAL energy. The movement of
the electrons along the line is commonly called as the current. Moreover, this
is also a type of kinetic energy because of the movement of the electrons.
Thus, the faster the movement of the electron the higher is the energy. </span>
<span>d. The type of energy that is stored in batteries or food is
CHEMICAL energy. This type of energy is that which is stored in the
bonds of the different chemical compounds. This is also most commonly released
when reaction between elements/compounds happen.</span>
<span>e. The energy that travels through vibrations and waves is
SOUND energy. As given above, this is associated with the movement or
vibrations of the matter. This is also a type of mechanical energy because of
the waves produced through to the vibrations.</span>
<span>f. The type of energy that is found in the nucleus and atoms
is the NUCLEAR energy. Nuclear
reactions most often released this type of energy simultaneous with the
generation of heat. </span>
<span>g. The stored energy is called the POTENTIAL energy. The
equation for this energy is mgh where h is the height, pertaining to the
position of the object. Once the object is released, it will be converted to
other forms of energy. </span>
<span>h. The answer to this item is THERMAL energy. This type of
energy can be transferred in three different ways: (1) conduction, (2)
convection, and (3) radiation.</span></span>
That would be the NOBLE GASES (Helium, Neon, Argon, Krypton, Xenon, Radon). Because these elements have a filled outer shell (thus giving them the full octet that other elements crave), they are stable elements under normal circumstances and as such resist chemical combination.
Plz note that under special conditions, noble gases such as Xenon and Radon can form compounds (Xenon Fluoride and Oxide; Radon Fluoride)
Answer:
0.54 mole
Explanation:
CH3COOH CH3CH2OH CH3COOCH2CH3 H2O
Initial concentration 1.0 mole 1.0 mole 0 mole 1.0mol
Change - x - x + x + x
Equilibrium (1.0 - x) (1.0 - x) x (1.0 + x)
K = [CH3COOCH2CH3]*[H2O]/[CH3COOH]*[CH3CH2OH]
x*(1.0+x)/(1.0-x)(1.0-x) = 4.0
x+x²=4*(1-x)²
x+x² = 4(1² - 2x + x²)
x + x² = 4 - 8x + 4x²
4 - 8x + 4x²- x² - x= 0
3x² - 9x + 4 = 0
x=2.5 , x=0.54
2.5 mole of acid cannot be esterified, because there is only 1.0 mole of acid,
so answer is 0.54 mole.
The answer would be: C. 160.3 J/mol*K
To solve this question, you need to know the equation for Gibbs free energy formula. Entropy is expressed as delta S. The temperature would be expressed as T. Don't forget that temperature use Kelvin as unit, not Celsius
The formula would be:
G= H- T*S
130.5 kJ/mol= 178.3kJ/mol - (25+273.15K)*S
(298.15K)*S=178.3kJ/mol - 130.5 kJ/mol
S= (47.8kJ/mol)/ 298.15K=
S= 0.1603 kJ/mol*K= 160.3 J/mol*K ------> 1kJ= 1000J
