50 points!! please help The four fundamental forces are arranged in the increasing order of their relative strength.

(A, B and C represent three of the fundamental forces.)

A < weak nuclear < B < C

Which statement is true about the fundamental forces represented by A and B?

Both have short range.
Both have infinite range.
Both act only between charged particles.
Both act only between uncharged particles.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)

b) nuclear ive learned that in a pedtrodic table
