Answer:

This reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen. Add 2 molecules of hydrogen peroxide and 2 molecules of water. Since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

3]Explanation: This reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen. Add 2 molecules of hydrogen peroxide and 2 molecules of water. Since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

4]Two moles of hydrogen peroxide H2O2 decomposes to produce two moles of water H2O and one mole of oxygen gas O2(g) , which then bubbles off

If 2.0 j of work Is done raising a 180 g Apple how far was it lifted
andrew11 [14]

The apple is lifted by 1.1 m

<u>Explanation</u>:

  • Given that, mgh = 2 J and mass of apple = 180g
  • Step 1: convert grams to kg as work is given in SI units.

                    180 g = 0.18 kg

  • Step 2: substitute in the formula for work done.

                    0.18 * 10 * h = 2

  • Step 3: calculate the value of h from this formula.

                      h = 2/1.8

                      h = 1.11 m
