In a molecule of methane, carbon (having four valence electrons) binds to four hydrogen atoms. How many lone pairs of electrons

will be represented in the Lewis structure of methane?

None. To bind with an hydrogem atom, the carbon needs to ''share'' one of it's valence electron's with the hydrogen's valence electron. Therefore, forming 4 bounds means the carbon atom will share it's 4 valence electrons and there will be no lone electrons.

How long must you immerse equipmemt and utensils in a non-chlorine sanitizing solution
Ivan

A non-chlorine chemical such as iodine may be used as a sanitizing solution. To use iodine as a sanitizing solution, it should be around 12.5-25 ppm in water that is at least 75° F. Utensils and equipment must be immersed for only 30 seconds because it may lose its effectivity if the pH level gets too high due to high temperature. Discoloration may also result if the utensils and equipment are in prolonged contact with the solution.

In equation δhsoln=δh1+δh2+δh3 which of the energy terms for dissolving an ionic solid would correspond to the lattice energy?
LekaFEV [45]
The dissolution of a solute in a solvent to form a solution usually occur in three steps, which are delta H1, delta H2 and delta H3. 
For dissolving an ionic solid, the lattice energy, which is the energy that is holding the ionic particles in place correspond to DELTA H2 and it is the energy that must be conquered. The higher the charge in the ionic solid, the higher the lattice energy. The lattice energy must be overcome in order for the solid to dissolve.

What volume of a 2.10 M NaCl solution is
cluponka [151]

Answer:

146.3g NaCl (mol NaCl/58.44g NaCl) = 2.50 mol NaCl

1.5M NaCl = 1.5 mol NaCl / 1 L = 2.5 mol NaCl / x L, solve for x

x L = 2.5 mol NaCl / 1.5 mol NaCl = 1.66 L

It gives the answer and all the working.

To put it another way:

Dividing the amount required by the molar mass

we quickly see that 2.5 moles are required.

One litre of 1.5 molar solution gives 1.5 moles

we need a further mole, which is 2/3 of 1.5 so 2/3 of a litre.
