Q3. How many grams of sulfuric acid, H2SO4, can be obtained from 578 grams of iron ore if the ore is 86.0% by mass FeS? The reactions involved are given below. Reactions happen with the
yield of 92.0%, 84.0% and 95.5% respectively
4 FeS + 702 2 Fe2O3 + 4 SO2
2 SO2 + O2 +2 SO3
SO3 + H20 H2SO4

How do scientists think that gravity affected the formation of our solar system?

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.

La reaccion entre monoxido de nitrogeno (no) y oxigeno para formardioxido de nitrogeno (no2) es un paso determinante para la formacion del smog, la reaccion es la siguiente: 2no + o2 = 2no2 cual sera el numero de moles de no2 que se formaran por la reaccion completa de 8 moles de oxigeno con suficiente monoxido?
