Explanation:
The reaction of potassium carbonate with hydrochloric acid is as follow -
Potassium Carbonate + Hydrochloric acid → Potassium Chloride + Water + Carbon Dioxide.
In the above reaction , the metal carbonate reacts with an acid to give salt , water and carbon dioxide .
The reaction is an exothermic reaction , as the release of carbon dioxide , is indicated by vigorous effervescence .
Hence ,
The temperature of the reaction increases a lot and hence the reaction is very dangerous .
Therefore , the reaction is very risky to perform.
Answer:
225 mL of water must be added.
Explanation:
First we <u>calculate how many HCl moles are there in 516 mL of a 0.191 M solution</u>:
- 516 mL * 0.191 M = 98.556 mmol HCl
Now we use that number of moles (that remain constant during the <em>dilution process</em>) to <u>calculate the final volume of the 0.133 M solution</u>:
- 98.556 mmol / 0.133 M = 741 mL
We can <u>calculate the volume of water required</u> from the volume difference:
Answer: it they are both in the same place
Explanation:I don’t know and don’t care loser
Answer:
A scientist is studying a shock wave from an earthquake, he is studying mechanical wave.
Explanation:
The shock waves are experienced during earthquake. At the area of increased pressure shock wave are created as the object in that places moves faster as compared to the speed of sound. Shock wave are type of mechanical wave. For its transfer it requires a medium. An electromagnetic wave can travel of its own without any medium, under electromagnetic wave gamma ray and radio wave comes. they are transverse wave.
Answer:
HEMOGLOBIN AND OTHER COMPOUNDS.
Explanation:
In the lungs, hemoglobin, known for its deep red color, reacts with oxygen to form oxyhemoglobin. Oxyhemoglobin travels through the bloodstream to cells, where it breaks down to form hemoglobin and oxygen, and the oxygen then passes into cells.
