help me i swear will mark you brainiest Nitric oxide, NO, is formed when oxygen and nitrogen from the air react in an internal combustion engine.
What is the right equation for this reaction

The combustion of hydrogen–oxygen mixtures is used to produce very high temperatures (approximately 2500 °C) needed for certain types of welding operations. Consider the reaction to be

H2(g)+1/2O2(g)=H2O(g)

change in enthalpy is -241.8 kJ

What is the quantity of heat evolved, in kilojoules, when a 160  g mixture containing equal parts of  H2 and O2 by mass is burned?

Explanation:

i hope this help sorry if it does not ok bye luv!!!

is there multiple choice answers?

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
