1.) balance the following chemical equation: + ₃po₄ → ₃po₄ + ₂o 2.) balance the following chemical equation: (oh)₃ + → ₃ + ₂o 3.) balance the following chemical equation: ₂o₃ + → ₂ + 4.) balance the following chemical equation: + ₂(co₃)₃ → ₃ + ₂co₃ there are four blanks on each and if there is no coefficient needed place a "1" in the blank

You will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. (refer to the walk-through video to locate the online lab within the online textbook).

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
