Answer:

Most higher risk volcanoes are far from California’s largest cities and several produce heat that’s used to generate electricity in what are the world’s most productive geothermal power plants, such as the Salton Buttes, 160 miles southeast of Los Angeles, and the Clear Lake Volcanic Field 85 miles north of San Francisco that powers the Geysers steam field.

A 100g sample of Carbon-14 has a half-life of 5 years. How much Carbon-14 is left after 10 years?

attashe74 [19]

Answer: The amount of carbon-14 left after 10 years is 25 g

Explanation:

Formula used :

$a=\frac{a_o}{2^n}$

where,

a = amount of reactant left after n-half lives = ?

$a_o$ = Initial amount of the reactant = 100 g

n = number of half lives = $\frac{\text {given time}}{\text {half life}}=\frac{10}{5}=2$

Putting values in above equation, we get:

$a=\frac{100g}{2^2}$

$a=\frac{100g}{4}=25g$

Therefore, the amount of carbon-14 left after 10 years is 25 g
