20 cm\(^3\) of hydrogen gas are sparked with 20cm\(^3\) of oxygen gas in an endimoeter at 373k (100\(^0\)C) and 1 atmosphere. The resulting mixture is cooled to 298 K (25 oC) and passed over calcium chloride. The volume of the residual gas is
40 cm 3
20 cm 3
30 cm 3
10cm 3
5cm 3

I disagree
residual gas=volume of excess gas +volume of product.from a balanced equation,excess gas used is 10 and volume of product is 20 and the sum is 30cm cube.
Yes Myschool is correct. The answet is D.10cm3 because the water produced is absorbed by the drying agent CaCl2.
Please, how come the oxygen gas is solved with 10cm³ instead of the 20cm³ given in the question ?
I think the answer should be 8cm^3 since the residual gas which occupied a volume of 10cm^3 at 373K to 298K
Yes the answer is correct cuz the water produced was dehydrated by calcium chloride so it will only remain oxygen
If 20 cm³ of hydrogen is sparked with 40cm³ of oxygen, what volume of gas will be produced?
