Answer: The concentration of hydroxide ions at this temperature is
Explanation:
When an expression is formed by taking the product of concentration of ions raised to the power of their stoichiometric coefficients in the solution of a salt is known as ionic product.
The ionic product for water is written as:
As
The concentration of hydroxide ions at this temperature is
Its white
It has temperature
It has density and
It has volume! :)
I am assuming that the problem ask for the pressure in
the system. To be able to calculate this, we first assume that the system acts
like an ideal gas, then we can use the ideal gas equation to find for pressure
P.
P V = n R T
where,
P = Pressure (unknown)
V = 0.17 m^3
n = moles of lng / methane
R = gas constant = 8.314 Pa m^3 / mol K
T = 200 K
We find for the moles of lng. Molar mass of methane = 16
kg / kmol
n = 55 kg / 16 kg / kmol
n = 3.44 kmol CH4 = 3440 mol
Substituting all the values to the ideal gas equation:
P = 3440 mol * (8.314 Pa m^3 / mol K) * 200 K / 0.17 m^3
P = 33,647,247 Pa
<span>P = 33.6 MPa</span>
A) The half-life of reactants in a nuclear decay reaction remains constant over time, but the mass of reactants that are consumed decreases
Explanation:
The rate at which elements decays radioactively is directly proportional to the number of atoms present in it. This is a simple first-order kinetics.
The half-life of a radioactive element is the time taken for half of the radioactive nuclei to disintegrates.
The shorter the half life, the larger the decay constant and the faster the decay process. If a radioactive decay is fast, the mass of the reactants will decrease significantly with time thereby producing more of the daughter isotopes.
The reactant in a radioactive decay are the parent isotopes. The products are the daughter isotopes.
