Consider that you collect hydrogen gas over water in an upside-down test tube. if the atmospheric pressure is 1.00, which of the following statements are true? select all that apply. a. the total pressure in the test tube is higher than the atmospheric pressureb. the total pressure in the test tube is equal to the atmospheric pressurec. the total pressure in the test tube is lower than the atmospheric pressured. the pressure of hydrogen in the test tube is higher than the atmospheric pressuree. the pressure of hydrogen in the test tube is equal to the atmospheric pressuref. the pressure of hydrogen in the test tube is lower than the atmospheric pressure

The pressure in a fluid is affected by which characteristics of that fluid

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl +4h2o enter the elemental symbol. view available hint(s) is reduced

Which type of precipitation would most likely form when the surface air temperature is slightly below freezing and the air temperature increases as you move upward away from the ground?
