No, water does not heat up or cool down faster than soil. This is because soil has lower specific heat. Specific heat is how long it takes for a substance to <span>heat up or cool down</span>
I got 9.25527 for the pKa
<span>then for the Henderson-Hasselbalch equation: </span>
<span>9.00=9.25527+log(.600/acid) </span>
10^(-.25527)=(.600/acid)correct to this line. Then
0.5556 = 0.6/acid and
acid = 0.6/0.5556 = 1.08 which is the reciprocal of your number)
<span>.5556/.600M=acid </span>
<span>acid=.925925...M </span>
<span>(.925925)*2.10L= Molarity</span>
Answer:
Explanation:
Entropy is concept which the describes the state of randomness or disorderliness of particles of a system. The entropic level depends on two important factors:
1. Temperature
2. Physical state of matter
For system A, in going from solid to liquid by dissolution in water the entropy increases. Solids are the most ordered substances followed by liquids. Gases are the most random.
For system B, moving from gas to a condensed state, there is a huge decrease in randomness of the system. The system tends towards more orderliness as the condensing forces changes a gas to a liquid. For this system, entropy reduces.
With newly discovered materials, nothing is yet know about them. Scientists don't know how to conduct physical/chemical experiments without damaging the element. Lethal substances or corrosive materials can be set off from combustion or decomposition. It would be difficult to determine the properties because no one knows what the element is made of. Chemical properties are often characterized by <span>reactivity with other chemicals, such as toxicity, coordination number, flammability, enthalpy of formation, the heat of combustion, and <span>oxidation states. It is difficult to measure those things when you have no idea what an element may be giving off. </span></span>
Chloroacetic acid is stronger than acetic acid because of the electron-withdrawing effect of chlorine. This effect is caused by the electronegativity.
