495 cm3 of oxygen gas and 877 cm3 of nitrogen gas, both at 25.0 °C and 114.7 kPa, are injected into an evacuated 536 cm3 flask. Find the total pressure in the flask, assuming the temperature remains
constant.

tracks, burrows, eggshells, nests, tooth marks, or gastroliths

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
