Elena makes the table below to determine the number of atoms of each element in the chemical formula 3(nh), so
total atoms
element
nitrogen
hydrogen
sulfur
oxygen
calculation
1 x 2 x 3
4x2x3
1 x 4 x3
- 4x3
24
12

vhat mistake did elena make?
she should not have multiplied the sulfur atoms by the subscript 4
she should not have multiplied the nitrogen atoms by the subscript 2
she should not have multiplied the oxygen atoms by the coefficient 3
she should not have multiplied the hydrogen atoms by the coefficient 3.

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

the closer the planet is to the sun, the larger the gravity

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
