To trigger a drug-dog alert, the necessary threshold level would be around 1 to 10 micrograms of methyl benzoate.

 

In the 1999 Furton study, it was stated that it would take 500 milligrams of cocaine in order to emit 1 to 10 micrograms of Methyl Benzoate.

 

A colorless liquid that is poorly soluble in water is one of the properties of <span>methyl benzoate.</span>

1. Calculate the heat change associated with cooling a 350.0 g aluminum bar from
Amanda [17]

Answer:

14175 j heat released.

Explanation:

Given data:

Mass of aluminium = 350.0 g

Initial temperature = 70.0°C

Final temperature = 25.0°C

Specific heat capacity of Aluminium = 0.9 j/g.°C

Heat changed = ?

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Heat change:

ΔT = Final temperature - initial temperature

ΔT = 25.0°C - 70°C

ΔT = -45°C

Q = m.c. ΔT

Q = 350 g × 0.9 j/g.°C  × -45°C

Q = -14175 j

Logs in a fire, and charged batteries are examples of?
vlabodo [156]

Answer:

Logs in a fire is an example of something burning, also changing its state of form. I think thats chemical change; going from wood to ashes. And charged batteries means they haven't been used yet or they were just charged, resulting in physical change.

Explanation:

I just learned this in science.

I hope this helps!

I really hope this isn't cheating and that you can actually do this for yourself and you just want to double check. To study just read the Scientific Method and memorize it
