Answer:

0.3 s.

Explanation:

Half-life of a first order reaction is defined as the the time taken for any fraction of the reaction to complete is independent of the initial concentration.

Half-life of a first order reaction, t° = 0.693/k

where,

t° = half-life of the reaction

k = rate constant

= 2.3 s^-1

Therefore,

t° = 0.693/2.3

= 0.30 s.

Vinvika [58]

Answer: $2.9(10)^{7} ft$

Explanation:

Firstly we need to know that $1 km=3280.84 ft$ , then we cam make the conversion:

$8848 km \frac{3280.84 ft}{1 km}=29,028,872.32 ft$ This is the height of Mount Everest in feet

However, we can express it using scientific notation by counting to the left the decimal spaces:

$29,028,872.32 ft \approx 2.9(10)^{7} ft$

Does the excess reactant get used up completely in a reaction??

Alex787 [66]

Answer:

In a chemical reaction, reactants that are not used up when the reaction is finished are called excess reagents. The reagent that is completely used up or reacted is called the limiting reagent, because its quantity limits the amount of products formed.
