Question

50 cm of hydrogen and 20 cm of oxygen were spared at room temperature, the product was liquid water. What volume of hydrogen remain
a) 50cm
b)30 cm
c) 15 cm
d) 10 cm​

Answer 1

Answer:

C) 15cm

Explanation:

Liquid water is H2O. Since hydrogen is 50 cm

and oxygen is 20 cm.

Then it is sprayed at room temperature then the

product is liquid water.

H2O = Hydrogen is 2 molecule since 50cm mean then mean should be used....

50x1/2 = 25.

the closure one is 15 since the volume of hydrogen will be remain
