6 0

Answer:

c.

Explanation:

This is because the chemist will get the average of the experiment from multiple attempts but not precision because the experiment is complex rather than simple.

Consider this reaction:
aleksklad [387]

Answer:   0.0345 sec

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

Rate=k[H_3PO_4]^2

k= rate constant = 46.6s^{-1}

Expression for rate law for first order kinetics is given by:

t=\frac{2.303}{k}\log\frac{a}{a-x}

where,

k = rate constant

t = age of sample

a = let initial amount of the reactant

a - x = amount left after decay process  

for completion of 20 % of reaction

t=\frac{2.303}{46.6}\log\frac{0.660}{\frac{20}{100}\times 0.660}

t=\frac{2.303}{46.6}\log\frac{0.660}{0.132}

t=0.0345sec

The time taken for the concentration of H_3PO_4 to decrease to 20% to its natural value is 0.0345 sec

Calculate the wavelength of a photon of light with a frequency of 6.17 x 1014 Hz.
PtichkaEL [24]

Answer:

4.86 × 10^-7m

Explanation:

Wavelength = C/f

C (Speed) of light = 3 × 10^8

f = 6.17 × 10^14

Wavelength = (3 × 10^8)/ (6.17 × 10^14)

= 4.86 × 10^-7m

when chlorine gains an electron to become a chloride ion with a -1 charge it ends up with the electron configuration of argon wh
RUDIKE [14]

Answer:

Only number of electrons of Chlorine and argon are going to be same remaining things like mass,reactivity,ionic radii, and so on will be different so if a chlorine gains a electron we can't call it argon!! chlorine is an diatomic gas, argon exist as monoatomic, chlorine can loose that electron and form bond with another cation in order to remove the charge density,, but argon is stable itself!
