What makes the waves pull away from the beach in a straight line?

Waves break when they reach a shallow coastline where the water is half as deep as the wave is tall. As a wave travels across the open ocean, it gains speed. When a wave reaches a shallow coastline, the wave begins to slow down due to the friction caused by the approaching shallow bottom.

Sulfur tetrafluoride, sf4, reacts slowly with oxygen, o2, to form sulfur tetrafluoride monoxide, osf4, according to the followin

Rus_ich [418]

Let a, b, c be the coefficients of the balanced reaction

a SF₄ + b O₂ ⇒ c OSF₄

The atom counts for each element among the reactants should be the same as with the products:

• S : a = c

• F : 4a = 4c

• O : 2b = c

If b = 1, it follows that a = c = 2. So the balanced reaction is

2 SF₄ + 1 O₂ ⇒ 2 OSF₄
