Answer:
The forward reaction will be favored.
Explanation:
The reaction is:
As per equation (equilibrium equation), there are two moles of gaseous molecules on product side and three moles of reactant side.
a) If we increase pressure, the volume will decrease.
b) Due to decrease in volume, the moles per unit volume will increase.
c) In order to attain equilibrium again, the system will shift in the direction where it can nullify this effect [Le Chatelier's principle]
d) This can be done, if system moves in the direction where number of moles of gaseous molecules are less, which is product side.
e) Thus forward reaction will be favored.
Answer:
4 pairs are needed for the bonds, leaving 1 lone pair. Each double bond uses 2 bond pairs and can be thought of as a single unit. There are 2 double bond units and 1 lone pair, which will try to get as far apart as possible - taking up a trigonal planar arrangement.

Answer:
A solid residue of limestone and some gypsum.
Explanation:
In step 2, some of the limestone and gypsum in the chalk dissolve in the water. When the mixture is filtered, the dissolved substances remain in the water. When the water is boiled off or evaporated, the solid substances remain behind.
For this problem, to determine the number of moles given the number of molecules, we use the Avogadro's number. This is an empirical value that relates the number of particles (e.g. atoms, molecules, sub-particles) in one mole of any substance. The value is 6.022×10²³ molecules/mol.
5.080×10¹⁶ molecules * 1 mol/6.022×10²³ molecules = <em>8.436×10⁻⁸ moles of hydrogen</em>
