The keg for the reaction
2 SO2(g) + O2(g) → 2 SO3(g) is
Keg = [SO3]^2/ {(SO2)^2 ( O2)}
Keg (equilibrium constant) is the ratio of of equilibrium concentration of the product raised to the power of their stoichiometric coefficient to the equilibrium concentration of the reactant raised to the power of their stoichiometric coefficient.
Answer/Explanation:
<u>Acids:</u>
Physical ⇒ Sour Taste, Increases the concentration of hydrogen ions when added to water
Chemical ⇒ Corrosive (Burns your skin and breaks down other materials), Forms hydrogen gas when it comes in contact with a metal, Forms salt and water when added to a base
Example: Tomatoes
<u>Bases:</u>
Physical ⇒ Bitter taste ( Never taste or smell a substance unless your parent/guardian tells you that it is okay), Slippery feeling(never touch a substance unless your parent/guardian tell you that is okay)
Chemical ⇒ Increases the concentration of hydroxide ions when added to water, Forms salt and water when added to an acid
Example: Soap, Clorox
[RevyBreeze]
Answer:
n= 2.55 moles
Explanation:
Using the formula of ideal gas law:
PV = nRT
nRT=PV
n= PV/RT
n= number of moles
R= Avogadro constant = 0.0821
T= Temperature in K => ºC + 273.15 K
V= volume in L
P= pressure in atm
n= (1 atm)(57.20 L) / (0.0821)(237.15 K)
n= 2.50 moles
C. Represents an oxidation-reduction reaction
Answer:
A
Explanation:
Radon is an alpha emitter. It emits alpha particles giving off gamma ray. It is a radioactive byproduct of radium-222.
Radon also penetrates the skin. This is because radon is a gas and chemically unreactive with most materials, it moves easily through very small spaces, such as those between particles of soil and rock, to the soil surface
Option B is wrong. It is produced during radioactive decay of radium and not uranium.
Option C is wrong. Radon is not a metallic element.
Option D is wrong also. It is not produced from photochemical smog
Option E is wrong. This is an extension of option B. Uranium is generally used in nuclear plant operations and not radium
