Asap ! how to balance equations with brackets? like pb(no3)2? how many of each element is there?

There is 1 lead (Pb) element, 2 nitrogen (N) elements and 6 oxygen (O) elements.

Explanation:

Brackets in chemistry work the same like in maths. You multiply each element in the bracket depending on the power. In this case, we have a nitrogen atom and three oxygen atoms, in brackets, with a power of 2. You multiply the nitrogen atoms by 2, ending up with 2 nitrogen atoms, and you multiply the oxygen atoms by 2, ending up with 6.

Pb2N4O12

Explanation: Pb = 1 X 2= 2 N = 2 x 2 = 4 O = 2+8+2 = 12

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
