4) At STP, calculate to the nearst whole number the volume of CO2 gas produced by mixing 20 g of co gas with an excess amount of oxygen gas according to the following equation: [C=12 , 0=16] 2CO(g) + O2(g) 2CO2(g)

Which type of stress results when two plates push against one another? a. compression b. tension c. force d. shear

Agas diffuses 1/7 times faster than hydrogen gas (h2). what is the molar mass of the gas? 100.10 g/mol 98.78 g/mol 86.68 g/mol 79.98 g/mol

For the reaction shown, calculate how many moles of no2 form when each of the following completely reacts. 2n2o5(g)→4no2(g)+o2(g) part a 1.0 mol n2o5 express your answer using two significant figures. nothing mol m o l request answer part b 5.4 mol n2o5 express your answer using two significant figures.
