A. Draw the line-bond structural formula for water (H2O), sodium chloride (NaCl), methane (CH4), hydrogen gas (H2), and ammonia (NH3). Then, characterize the type of bond that each molecule contains (ie. ionic, nonpolar covalent, polar covalent).

B.
On the molecules listed in #1, draw the relative position(s) of the shared electrons based on the electronegativity of the atoms.

*will mark you brainliest + 15 points ** why does the equilibrium of a system shift when the pressure is increased? a. to maximize the stress on the system b. to stop restoring equilibrium to the system c. to increase the total moles of gas in the system d. to decrease the total moles of gas in the system

What is a property of a double replacement reaction

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
