(05.07 LC) The image represents the reaction between a certain number of molecules of N2 and H2.

Two squares are shown. Inside the left square one unit of two joint circles if shown. The molecular formula of nitrogen gas is shown on top of this square. The square on the right has four units of two joint circles. The molecular formula for hydrogen gas is shown on top of this square

If the maximum amount of NH3 is formed during the reaction, what is the leftover reactant? (4 points)

Group of answer choices

One molecule of N2

One molecule of H2

Two molecules of N2

Two molecules of H2

Air pressure is measured in pascals. for a professional american football game, the ball should be inflated to about 90,000 pascals. scientists studied the effects of air temperature on the pressure inside american footballs by taking these steps: 1. prepare 100 footballs. 2. measure each football's air pressure. 3. divide footballs into 10 groups. 4. place the groups in different lockers cooled to different air temperatures. 5. after 12 hours, remove the footballs from lockers. 6. measure each football's pressure again. 7. compare the new pressures to the starting pressures. what two terms best describe the variable "air pressure inside the football" in this experiment? independent, qualitative independent, quantitative dependent, qualitative dependent, quantitative
