Hãy xác định thành phần % thể tích của hỗn hợp khí gồm SO2, CO2 và CO. Biết rằng: - Tỉ khối của hỗn hợp khí đối với khí hiđro là 20,8.

- Khi cho 10 lít hỗn hợp đó sục qua dung dịch kiềm dư thì thể tích khí còn lại là 4 lít.

Biết thể tích các khí đều đo ở cùng điều kiện nhiệt độ và áp suất.

Đáp số: 20% SO2; 40% CO2 và 40% CO

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap

How are isotopes of the same chemical element alike? how are they different?

The atoms of a solid aluminum can are close together, vibrating in a rigid structure. if the can is warmed up on a hot plate, what happens to the atoms?
