Answer:
(A)0.25L
Explanation:
By combination of Boyle's law and Charles law to obtain the general gas equation, we have:
P1V1/T1=P2V2/T2
P1=Inital pressure=1.00 atm
V1=Inital volume=4.91L
T1=Initial temperature=20°C=20+273=293Kelvin
P2=Final pressure=5.2atm
T2=Final temperature=(-196+273K)=77K
V2= final volume=?
by making V2 the subject of the above general gas equation
we have V2=P1V1T2/P2T1
=1×4.91×77/5.2×293
=0.248L
The answer is B
To write the equilibrium constant for an equation, all you have to do is divide the products by the reactants. The reactants are always on the left side, and the products are always on the right side. The coefficients of the elements will be written as the exponent of that same element. However, in this equation, we do not have to write any exponents, as there are no coefficient but 1.
Answer:
Hydrolysis is any chemical reaction in which a molecule of water ruptures one or more chemical bonds.
Explanation:
Example:
Dissolving a salt of a weak acid or base in water is an example of a hydrolysis.
In gamma decay, no change in proton number occurs, so the atom does not become a different element
