Write a skeletal chemical equation for the process described. A car engine burns gasoline to power the movement and other functions of a car. The main component of gasoline used for this is known as octane (
CH.). In the pistons of the engine, this octane is exposed to oxygen (0); from the air, a spark is used to heat the mixture. This causes the octane to
burn with the oxygen, releasing carbon dioxide (CO) and water vapor (H,0). This causes the piston to expand rapidly, producing the energy needed to
operate the car.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
