An inefficient appliance costs less to operate than an efficient one, because it takes more energy to do the same job is "False".
<u>Answer:</u> Option B
<u>Explanation:</u>
Energy efficiency is about utilizing less energy consuming appliances than inefficient appliance which consume more energy to do the similar job and support for avoiding high energy bills and unnecessary pollution in the process.
The choice for energy efficiency is "ENERGY STAR LABEL" makes it known to consumers or businesses that a product, home or building is more energy efficient than others on the market.
ENERGY STAR and its partners have managed to save nearly 4 trillion kilowatt-hours of electricity from American families and businesses in 2017 and resulted into 3 billion metric tons of greenhouse gas reductions.

Answer:
If both fluorine atoms are combine than each atom have 8 valance electrons and total valance electrons in both atoms are 16.
Explanation:
Fluorine is halogen atom. The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Halogens are very reactive these elements can not be found free in nature. Their chemical properties are resemble greatly with each other. As we move down the group in periodic table size of halogens increases that's way fluorine is smaller in size as compared to other halogens elements.
There seven valance electrons in each halogen atom. They need one electron to complete the octet.
Fluorine atom combine with its another atom through covalent bond and share its one of valance electron with other atom thus both have 8 valance electrons and total valance electrons in both atoms are 16.
