We all have favorite things we eat, watch on TV, hobbies we like, places we love to travel, etc. Either write or draw picture of you doing one of your favorite things. Then follow these directions...
<u>Answer:</u> The correct answer is Option b.
<u>Explanation:</u>
To calculate the amount of heat absorbed or released, we use the following equation:
.....(1)
where, q = amount of heat absorbed or released.
m = mass of the substance
c = heat capacity of water = 4.186 J/g ° C
= Change in temperature
We are given:
![m=30g\\\Delta T=[40-0]^oC=40^oC\\q=?J](https://tex.z-dn.net/?f=m%3D30g%5C%5C%5CDelta%20T%3D%5B40-0%5D%5EoC%3D40%5EoC%5C%5Cq%3D%3FJ)
Putting values in equation 1, we get:

q = 5023.2 J
We are given:
![m=40g\\\Delta T=[40-30]^oC=10^oC\\q=?J](https://tex.z-dn.net/?f=m%3D40g%5C%5C%5CDelta%20T%3D%5B40-30%5D%5EoC%3D10%5EoC%5C%5Cq%3D%3FJ)
Putting values in equation 1, we get:

q = 1674.4 J
Heat gained by Trial 1 than trial 2 = 
Hence, the amount of heat gained in Trial 1 about 3347 J more than the heat released in Trial 2.
Thus, the correct answer is Option b.
Answer:
it would become darker. there would be a higher level of water pressure. and there would be less animals, or different alimals.
Explanation:
The given data is as follows.
Concentration of standard NaOH solution = 0.1922 M
Let the original acid solution concentration be x.


= 0.1 x M
= 10.00 mL (given)
The reaction equation is as follows.

Concentration × Volume of
= Concentration × Volume of NaOH

x = 1.314 M
Therefore, we can conclude that the concentration of the original sulfuric acid solution is 1.314 M.
This is a symbiotic relationship called commensalism if the tree root is the only one to benefit.
