4 0
2 H2 + O2 = 2 H2O

1 mole O2 --------------- 2 moles H2O
13.35 moles O2 -------- ( moles H2O)

moles H2O = 13.35 x 2 / 1

<span>= </span>26.7 moles of H2O

<span>hope this helps!</span>

A certain first-order reaction (A→products) has a rate constant of 8.10×10−3 s−1 at 45 ∘C. How many minutes does it take for the
stira [4]

Answer:

The answer is 5.7 minutes

Explanation:

A first-order reaction follow the law of Ln [A] = -k.t + Ln [A]_{0}. Where <em>[A]</em> is the concentration of the reactant at any <em>t</em> time of the reaction, [A]_{0} is the concentration of the reactant at the beginning of the reaction and <em>k</em> is the rate constant.

Dropping the concentration of the reactant to 6.25% means the concentration of A at the end of the reaction has to be [A]=\frac{6.25}{100}.[A]_{0}. And the rate constant (<em>k</em>) is 8.10×10−3 s−1

Replacing the equation of the law:

Ln \frac{6.25}{100}.[A]_{0} = -8.10x10^{-3}s^{-1}.t + Ln[A]_{0}

Clearing the equation:

Ln [A]_{0}.\frac{6.25}{100} - Ln [A]_{0} = -8.10x10^{-3}s^{-1}.t

<em>Considering the property of logarithms: </em>Ln A - Ln B = Ln \frac{A}{B}

Using the property:

Ln \frac{[A]_{0}}{[A]_{0}}.\frac{6.25}{100} = -8.10x10^{-3}s^{-1}.t

Clearing <em>t </em>and solving:

t = \frac{Ln \frac{6.25}{100} }{-8.10x10^{-3}s^{-1} } = 342.3s

The answer is in the unit of seconds, but every minute contains 60 seconds, converting the units:

342.3x\frac{1min}{60s} = 5.7min

Answer: I believe this is the answer: The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.

Good luck on assignment! :)
