No, everything with a mass has gravity. That's why the planets orbit the sun. That's why moons orbit planets. The asteroid belt etc etc. If you drop something heavy on the moon, it'll still fall to the ground, this proves that there is gravity on the moon. The Mars rover is still on Mars, it hasn't floated away, this proves there is gravity on Mars.

Explanation:
Hello!
In this case, for the chemical reaction between hydrochloric acid and barium peroxide is:
Thus, since the barium peroxide (169.33 g/mol) and hydrochloric acid (36.45 g/mol) are reacting in a 1:2 mole ratio, we need to identify the limiting reactant first by computing the yielded moles of hydrogen peroxide by each reactant:
That's why the HCl is the limiting reactant, so the resulting mass of hydrogen peroxide, theoretical yield, is:
