Suppose we have made 3 measurements of the volume occupied by a gas and 20 measurements of its pressure. Which of the following statements is considered incorrect?(A). Of the 3 volume values ​​measured, we can safely discard the one that is furthest from the mean. It is not advisable to discard pressure values(B). There is no single criterion that we must follow in order to discard values. Therefore, it could be the case that each experimenter rejects a different number of data(C). It would be good practice for the number of discarded values ​​to be less than 5%(D). The so-called 4δ criterion advises discarding measurements that fall outside an interval with a center at the mean and a width 8 times the mean deviation

Is there a difference between a homogeneous mixture of hydrogen and oxygen in a 2:1 ratio and a sample of water vapor? Explain.

A sample of methane gas at a pressure of 0.947 atm and a temperature of 29.0 °C, occupies a volume of 711 mL. If the gas is allowed to expand at constant temperature until its pressure is 0.504 atm, the volume of the gas sample will be | mL.

The mass of the plastic bag, baking soda, and vinegar before the reaction was equal to the mass of the plastic bag, baking soda, and vinegar after the reactionBubbles were produced during the reaction which was evidence a gas was being producedThe plastic bag did not change in any way which indicated it was not involved in the reactionThe mass of the baking soda was exactly equal to the mass of the vinegar used to create the reaction.

Can you help me this question? This is a molar mass of gas-laboratory assignment.

P1A.10 Ozone is a trace atmospheric gas which plays an important role in screening the Earth from harmful ultraviolet radiation, and the abundance of ozone is commonly reported in Dobson units. Imagine a column passing up through the atmosphere. The total amount of O3 in the column divided by its cross-sectional area is reported in Dobson units with 1 Du =0.4462 mmol m−2. What amount of O3 (in moles) is found in a column of atmosphere with a cross-sectional area of 1.00 dm2 if the abundance is 250 Dobson units (a typical midlatitude value)? In the seasonal Antarctic ozone hole, the column abundance drops below 100 Dobson units; how many moles of O3 are found in such a column of air above a 1.00 dm2 area? Most atmospheric ozone is found between 10 and 50 km above the surface of the Earth. If that ozone is spread uniformly through this portion of the atmosphere, what is the average molar concentration corresponding to (a) 250 Dobson units, (b) 100 Dobson units?

a) Boyle's Law states the the volume and pressure of a gas are inversely proportional. Name the three units of the constant of proportionality between pressure and volume in alphabetical order. b) Charles' Law states that the volume and temperature of a gas are proportional. See image. Name the units of the proportionality constant between pressure and temperature in Charles' Law. Use ^ to indicate superscript. So m would be m^7. Use "deg" for degree.

Item 4 4 of 16 I Review I Constants I Periodic Table Gases are different from solids and liquids. In a sample of gas, the molecules are far apart. The gas molecules also move around and collide with each other as well as with the walls of the container. These collisions generate pressure. The pressure of a gas can be measured in different units. One convenient unit of measure is called the atmosphere (atm) because it is based on atmospheric pressure. At sea level, the average pressure is 1 atm. As you get higher in altitude, the pressure steadily drops until you leave the atmosphere, where the pressure is very close to 0 atm. Part C The table below shows the different commonly used units of measuring gas pressure. Use this table in the pressure unit conversions. High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purify chemical substances. The pressures used in this procedure range from around 500 kilopascals (500,000 Pa) to about 60,000 kPa…

A student finds a container of potassium metal containing an unknown amount of the reactive metal. The student decides to slowly add an excess of water to the container and trap any gas that is evolved. The student then reacts the trapped gas with an excess of gold (III) nitrate solution. This produces 22.57g of metallic gold. How much potassium metal was in the original container

An ideal gas at standard temperature and pressure (0 °C, 1 atm) has its temperature reduced at constant pressure until the volume is reduced to 46% of the original. What is the new temperature? State your answer.in 0 °C without units to three significant figures.
