For the reaction 2H2O > 2H2 + O2 what is the total number of moles of O2 produced from the complete decomposition of 8 moles H2O .
b- 3 moles
c- 4 moles
d- 8moles

In the space, show a correct numerical setup for calculating the number of moles of co2 present in 11 grams of co2

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.
