Answer:
five half lives
Explanation:
Half-life is the time required for a quantity to reduce to half of its initial value.
How many half lives it would take to reach 3.13% form 100% of it's initial concentration:
100% - 50% : First Half life
50% - 25%: Second Half life
25% - 12.5%: Third Half life
12.5% - 6.25%: Fourth Half life
6.25% - 3.125%: Fifth Half life
This means it would take five half lives to get to 3.125% (≈ 3.13%) of it's original concentration.
Answer:
Explanation:
Hello,
In this case, it is convenient to rewrite the chemical reaction considering the COCl₂ as the reactant, so we must invert the equilibrium constant as shown below:
Thus, by introducing the change due to reaction's progress, one obtains:
Solving for via quadratic equation or solver, one obtains:
Clearly, the solution is for which the total pressure at equilibrium is:
Best regards.
I believe it is B. A series circuit has one path for electrons, but a parallel circuit has more then one path.
