Answer last question I will give you brainlessly

Achlorine atom has 17 protons and 18 neutrons. what is its mass number? what is its atomic number?

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )

Which is an advantage of subdividing science into different areas?
