Answer:

Explanation:

you start from the double bond for naming of hydrocarbons, ethene has double bond has its characteristics, we have seven chains, so the answer is 1-heptene

If the half-life of 37Rb is 4.7x101 years, how long would it take for 0.5 grams of a 2 gram sample to radioactively decay?

k0ka [10]

<u>Answer:</u> The time required will be 19.18 years

<u>Explanation:</u>

All the radioactive reactions follows first order kinetics.

The equation used to calculate half life for first order kinetics:

$k=\frac{0.693}{t_{1/2}}$

We are given:

$t_{1/2}=4.7\times 10^1yrs$

Putting values in above equation, we get:

$k=\frac{0.693}{4.7\times 10^1yr}=0.015yr^{-1}$

Rate law expression for first order kinetics is given by the equation:

$k=\frac{2.303}{t}\log\frac{[A_o]}{[A]}$

where,

k = rate constant = $0.015yr^{-1}$

t = time taken for decay process = ?

$[A_o]$ = initial amount of the reactant = 2 g

[A] = amount left after decay process = (2 - 0.5) = 1.5 g

Putting values in above equation, we get:

$0.015yr^{-1}=\frac{2.303}{t}\log\frac{2}{1.5}\\\\t=19.18yrs$

Hence, the time required will be 19.18 years

Given:1 inch = 2.54 cm (exact)1 pound = 454 g1 Liter = 1.0b quarts1 foot = 12 inches1 galion = 4 quarts1 pound = 16 ouncesCalcul

svet-max [94.6K]

We have to convert 0.18 km into feet

First, we need to know the conversions:

1 inch = 2.54 cm (exact)

1 pound = 454 g

1 Liter = 1.0b quarts

1 feet = 12 inches

1 galion = 4 quarts

1 pound = 16 ounces

0.18 km x (1 feet/12 inches) x (1 inch/2.54cm) x (1000 m/1 km) x (100 cm/1 m) = 590 ft

Answer: 590 ft (2 significant figures)
