What will be the percent error of gas volume when 34.2 mL of gas is produced when H2SO4 reacts with 0.0900 g of zinc at 21.5 oC, and the laboratory pressure is 752.6 mmHg?

Find the protons, electrons and neutrons for strontium with a mass of 83

Which statement is best described as a atom

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.
