How many total atoms are represented by this formula 3naoh? a.1 b.3 c.6 d.

D. 9.  

Step-by-step explanation:

One formula unit of NaOH contains three atoms:  1 Na, 1 O, and 1 H.

3 formula units × (3 atoms/1 formula unit) = 9 atoms

 D. 9

Explanation:

Atom is the smallest unit of matter which may or may not have independent existence. Example:

Molecule is the smallest unit of matter which has a independent existence. Example:

1 molecule of has 1 atom of sodium, 1 atom of oxygen and 1 atom of hydrogen and thus total of 3 atoms.

Thus if 1 molecule of has total of 3 atoms.

Thus 3 molecules of has total of =

Thus 9 atoms are represented by this formula

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.
