Answer: 61.44 barrels of crude oil are required to run your car for a year.
Step-by-step explanation:
A barrel of crude oil has a volume of 42 gallons, only approximately 45% of which is processed into gasoline. This means that the processed gasoline from 1 barrel of crude oil would be
45/100 × 42 = 18.9 gallons
If your car achieves 31 mi/gal, and you drive 36,000 miles in one year, it means that the number of gallons of gasoline that you would require in a year is
36000/31 = 1161.29 gallons of gasoline
Since 1 barrel of crude produces 18.9 gallons of gasoline, then the number of barrels of crude that would produce 1161.29 gallons of gasoline would be
1161.29/18.9 = 61.44 barrels
A chemical reaction is a spontaneous reaction is determined by the Gibb's energy and enthalpy of the reaction whether it is exothermic or endothermic. The factors that apply here are heat and entropy. Gibb's energy is related to entropy. Answers are D. and E

Explanation:
Beryllium forms an ion with 2 electrons in its outermost shell. Hence<u> the charge on the element is 2+</u>, that is, Be2+. In order for Be to form a stable bond with another element, <u>such an element must have a deficit of electrons in its outermost shell</u>. Beryllium will have to donate its 2 electrons to this element for its self-stability.
