Ammonia reacts with O2 to form either NO or NO2 according to the unbalanced equations shown below: NH3 + O2 → NO + H2O NH3 + O2 → NO2 + H2O In an experiment, 10 mol NH3 and 15.1 mol O2 are intially placed in a closed flask. After the reaction all the NH3 has reacted and 2.4 mol O2 remain. Calculate the number of moles of NO in the flask after reaction. Round your answer to two significant figures.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
