In preparation for a demonstration, your professor brings a 1.50−l bottle of sulfur dioxide into the lecture hall before class to allow the gas to reach room temperature. if the pressure gauge reads 488 psi and the lecture hall is 23°c, how many moles of sulfur dioxide are in the bottle? in order to solve this problem, you will first need to calculate the pressure of the gas. hint: the gauge reads zero when 14.7 psi of gas remains.

The following reaction shows the products when sulfuric acid and aluminum hydroxide react. al(oh)3 + h2so4 → al2(so4)3 + h2o the table shows the calculated amounts of reactants and products when the reaction was conducted in a laboratory. initial mass and yield sulfuric acid aluminum hydroxide initial amount of reactant 40 g 15 g theoretical yield of water from reactant 14.69 g 10.38 g what is the approximate amount of the leftover reactant? 11.73 g of sulfuric acid 10.33 g of sulfuric acid 11.12 g of aluminum hydroxide 13.67 g of aluminum hydroxide

There is a single path for electrons. the current decreases when additional resistors are added. the current will be the same in each resistor. these statements best describe a(n) circuit.

Can someone me with 3 and 4 plz. this is for masteries test.
