Chemical changes occur when asubstance combines with another to form a new substance, called chemicalsynthesis or, alternatively, chemicaldecomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.

The first-order rate constant for the decomposition of n2o5, 2n2o5(g)→4no2(g)+o2(g) at 70∘c is 6.82×10−3 s−1. suppose we start w
torisob [31]

The rate constant for 1st order reaction is

K = (2.303 /t) log (A0 /A)

Where, k is rate constant

t is time in sec

A0 is initial concentration

(6.82 * 10-3) * 240 = log (0.02 /A)

1.63 = log (0.02 /A)

-1.69 – log A = 1.63

Log A = - 0.069

A = 0.82

Hence, 0.82 mol of A remain after 4 minutes.

Butoxors [25]

Answer:

In a voltaic cell (one that happens spontaneously), electrons flow from a negative electrode to a positive electrode (anode  cathode). The reaction that happens is a redox reaction where the anode is oxidized (goes from a solid to an ion) and the cathode is reduced (going from an ion to a solid).
