Question

What demonstrating releases of seo2 during respiration the teacher use lime water instead of plain water what

Answer 1

Step-by-step explanation:

Correct option is

A

Milky

Carbon dioxide gas turns lime water milky. The fact that carbon dioxide is produced during respiration can be shown by demonstrating the effect of inhaled air and exhaled air on lime-water. From the experiment, we understand that the tube containing inhaled air is less milky while the tube with exhaled air is milkier. This shows that less carbon dioxide is present in inhaled air but much more carbon dioxide is present in exhaled air. From this observation we conclude that carbon dioxide is produced during respiration (which comes out in exhaled air).

Answer 2

Step-by-step explanation:

lime water is used because CO2 makes lime water milky
