Well first you need to convert all the substances into there other name. For example: you would change #1 to Mg+O=MgO. That would be known as a synthesis reaction.

Explain, in terms of ions, why the aqueous solution in the cell conducts an electric current.

a_sh-v [17]

The solution contains mobile ions. These ions can move freely. These ions, Na+ and Cl-, both in aqueous forms, move freely, allowing the charge to flow from the anode to cathode (because the battery is discharging, otherwise it would be cathode to anode).

In the reaction, A → Products, the rate constant is 3.6 × 10−4 s−1. If the initial concentration of A is 0.548 M, what will be t

Arada [10]

Answer:

$\large\boxed{\large\boxed{0.529M}}$

Explanation:

Since the <em>rate constant</em> has units of <em>s⁻¹</em>, you can tell that the order of the reaction is 1.

Hence, the rate law is:

$r=d[A]/dt=-k[A]$

Solving that differential equation yields to the well known equation for the rates of a first order chemical reaction:

$[A]=[A]_0e^{-kt}$

You know [A]₀, k, and t, thus you can calculate [A].

$[A]=0.548M\times e^{-3.6\cdot 10^{-4}/s\times99.2s}$

$[A]=0.529M$
