Communities is all the populations living in an ecosystem at the same time. A predator-prey relationship is an organism that eats another organism.
Answer:
25.907°C
Explanation:
In Exercise 102, heat capacity of bomb calorimeter is 6.660 kJ/°C
The heat of combustion of benzoic acid is equivalent to the total heat energy released to the bomb calorimeter and water in the calorimeter.
Thus:
= heat of combustion of benzoic acid
= heat energy released to water
= heat energy released to the calorimeter
Therefore,
1.056*26.42 = [0.987*4.18 + 6.66]( - 23.32)
27.8995 = [4.12566+6.660]( - 23.32)
( - 23.32) = 27.8995/10.7857 = 2.587
= 23.32 + 2.587 = 25.907°C
Answer:
The patented TRUE-TECH Self-Heating Technology is a simple combination of food grade iron and magnesium powder, salt, and water. When the contents of the water pouch are poured over the heater pad, the Food Heater releases enough heat to warm-up a pre-cooked meal 100 degrees Fahrenheit in approximately 10 minutes.

Answer:
Explanation:
Writing the equation properly:
(CH₃)₃N + H₂O ⇄ (CH₃)₃NH⁺ + OH⁻
HNO₃ + H₂O ⇄ H₂O + NO₃⁻
The bronsted-lowry theory defines an acid as a proton donor and a base as a proton acceptor.
In a bronsted-lowry acid-base reaction, the original acid gives up its proton and becomes a conjugate base. Also, the original base accepts a proton and becomes a conjugate acid. For every acid, there is a conjugate base and for every base there is a conjugate acid.
What differentiates an acid from its conjugate base is a proton. The difference between a base and its conjugate acid is a proton.
(CH₃)₃N + H₂O ⇄ (CH₃)₃NH⁺ + OH⁻
Bronsted-lowry base acid conjugate acid conjugate base
HNO₃ + H₂O ⇄ H₃O⁺ + NO₃⁻
