Answer:
=> moles = Given mass/molar mass
=> 0.787 = Given mass/(39 + 12 + 14)
=> 0.787 = Given mass/65
=> mass = 0.787 × 65
=> <u>mass = 51.155 g</u>
Answer:
This process is called Photochemical smog
Explanation:
Answer:
The closer a planet is to the Sun, the stronger the Sun's gravitational pull on it, and the faster the planet moves. The farther it is from the Sun, the weaker the Sun's gravitational pull, and the slower it moves in its orbit.
Take mass of zinc divided by the relative molecular mass - 30 for zinc ( from periodic table)
