You are made of mostly 6 elements: Oxygen, Carbon, Hydrogen, Nitrogen, Calcium, and Phosphorus. Some of these elements combine to form compounds in your body.
The layer of Earth’s atmosphere that has the coldest temperature range is mesosphere
<u>Answer:</u> The final temperature will be 
<u>Explanation:</u>
Calculating the heat released or absorbed for the process:
In a system, the total amount of heat released is equal to the total amount of heat absorbed.
OR
......(1)
where,
C = heat capacity of water = 
= mass of water of sample 1 = 100.0 g
= mass of water of sample 2 = 71.0 g
= final temperature of the system = ?
= initial temperature of water of sample 1 = 
= initial temperature of the water of sample 2 = 
Putting values in equation 1, we get:
Hence, the final temperature will be
Answer:0.00000009
Explanation:
9.11 × （1/1000000000）=0.00000009
Answer:
When concentrated hydrochloric acid is added to a very dilute solution of copper sulfate, the pale blue solution slowly turns yellow-green on the formation of a copper chloride complex.
