D.
Endothermic reactions absorb heat, which is why they have the prefix "endo" and exothermic reactions release heat, which is why they have the prefix "exo"

Geologists use the decay of potassium-40 in volcanic rocks to determine their age. Potassium-40 has a half-life of 1.26 109 year
melomori [17]

Answer:

m_{o} \approx 3.247\times 10^{-7}\,g

Explanation:

The mass of radioactive isotope at a certain time is given by the following expression:

m(t) = m_{o}\cdot e^{-\frac{t}{\tau} }

Time constant can be calculed in terms of half-life:

\tau = \frac{t_{1/2}}{\ln 2}

\tau = \frac{1.26\times 10^{9}\,yr}{\ln 2}

\tau = 1.818\times 10^{9}\,yr

The initial mass is:

m_{o} = \frac{2.73\times 10^{-7}\,g}{e^{-\frac{3.15\times 10^{8}\,yr}{1.818\times 10^{9}\,yr} }}

m_{o} \approx 3.247\times 10^{-7}\,g

Which of the following threats to biodiversity is a result of over-fishing?
LUCKY_DIMON [66]
Overfishing is an example of human impact on biodiversity.
In simple terms, overfishing means that the sea animals hunted for food ( fishes, crustaceans, mollusks etc.)  in a year are hunted in numbers greater than the number of newborn individuals of that species in that year. This means that the populations of these animals do not have the time to regrow their numbers.
This results in a dramatic decline of populations of many marine animals.

Determine the specific heat of a material if a 35-9 sample absorbed 96 ) as it was heated from 293 Kto 313 K.
Norma-Jean [14]

This is an incomplete question, here is a complete question.

Determine the specific heat of a material if a 35 g sample absorbed 96 J as it was heated from 293 K to 313 K.

Answer : The specific heat of a material is, 0.137 J/g.K

Explanation :

Formula used to calculate the specific heat of a material is:

q=m\times c\times (T_2-T_1)

where,

q = heat absorbed = 96 J

m = mass of sample = 35 g

c = specific heat capacity of material = ?

T_1 = initial temperature = 293 K

T_2 = final temperature = 313 K

Now put all the given values in the above formula, we get:

96J=35g\times c\times (313-293)K

c=0.137J/g.K

Therefore, the specific heat of a material is, 0.137 J/g.K
