<span>1: Calculate the Formal Charge of C. Carbon (C) is in group 14, so that means it has 4 valence electrons. . 2: Calculate the Formal Charge of Oxygen on the Left. . 3: Calculate the Formal Charge of Oxygen on the Right. .<span>4: Check the Overall Charge.
I hope this helps:)

Answer:
Ice cubes, glass of tea, and butter
Explanation:
Like it said in the hint, the molecules will only speed up if they gain heat. This means in order for the object to heat up it will have to have a temperature that is less than the temperature in the room. Ice cubes, glass of tea, and butter are the three objects that have a temperature less than 72 degrees so when they are placed in the 72 degrees room they will heat gain heat (therefore making the molecules move faster)
Answer: True no need for an explanation..
Since Titan orbits roughly along Saturn's equatorial plane, and Titan's tilt relative to the sun is about the same as Saturn's, Titan's seasons are on the same schedule as Saturn's—seasons that last more than seven Earth years, and a year that lasts 29 Earth years.
Types of Bonds can be predicted by calculating the difference in electronegativity.
If, Electronegativity difference is,
Less than 0.4 then it is Non Polar Covalent
Between 0.4 and 1.7 then it is Polar Covalent
Greater than 1.7 then it is Ionic
For Li and O,
E.N of Oxygen = 3.44
E.N of Lithium = 0.98
________
E.N Difference 2.46 (Ionic Bond)
For Cl and F,
E.N of Fluorine = 3.98
E.N of Chlorine = 3.16
________
E.N Difference 0.82 (Mildly Polar Covalent Bond)
For Ca and S,
E.N of Sulfur = 2.58
E.N of Calcium = 1.00
________
E.N Difference 1.58 (Polar Covalent Bond)
