Answer:
O B. Convert the 10 g of NaCl to moles of NaCl.
Explanation:
The formula for finding the molality is m=moles of solute/kg of solvent. The solute for this question is NaCl and the solvent is water.
(10g NaCl)(1 mol NaCl/58.44g NaCl)=0.1711 mol NaCl
58.44 is the molar mass of NaCl
m=0.1711 mol NaCl/2 kg H2O
m=0.085557837
Explanation:
it is negative acceleration
Explanation:
The octet rule is a rule that governs how atoms combines with each other. It postulates that atoms will prefer to have the stable configuration of noble gases by having eight electrons in their outermost shell.
Compounds forms when atoms combines to attain stability. The atoms of some elements shows no tendency to combine with themselves or other kinds of atoms because their outer energy levels are completely filled.
The driving force for many interatomic bonding is the tendency to have completely filled outer energy levels like the noble gases.
The various interatomic bonds are formed in the bid of the atoms to be isoelectronic in the outer energy level with the noble gases.
This more stable form may be achieved by losing, or gaining electrons or the sharing of pairs of electrons.
