In an industrial process, the temperature of a fixed amount of gas in a rigid container drops from 50 degrees Celsius to 25 degrees Celsius. What will be the final pressure in the container if the initial pressure is 3.8 atmospheres? 1.9 atm 3.5 atm 4.1 atm ***7.6 atm Which of the following is an example of -ΔS? Picking up marbles and placing them in a sack Paint spilling onto the floor from a can Grains of sand being dropped onto the carpet ***Dropping a drop of red dye into water The equilibrium constant: is described as K = [products]/[reactants] without reference to coefficients within the chemical equation is described as K = [reactants]/[products] without reference to coefficients within the chemical equation ***is described as K = [reactants]/[products] with reference to coefficients within the chemical equation (used as superscripts) is described as K = [products]/[reactants] with reference to coefficients within the chemical equation (used as superscripts) Which of the following is NOT TRUE about alpha emissions? Result in new element whose mass number is two units less than the old element ***Less penetrating than beta emissions Most common in elements with atomic number > 83 Written as 42He Which particle is emitted when an atom of 23491Pa changes to 23492U? alpha particle ***beta particle gamma particle positron Fusion refers to the splitting of an atomic nucleus into fragments of roughly the same mass amount. *** True False
