Answer:
b. Lithium
Explanation:
<u>Lithium-ion batteries (LIB) is a rechargeable battery</u>. It was first proposed by M stanley Whittingham in 1970s. These kind of batteries are commonly used in electrical vehicles and portable electronics. It also have military , naval and aerospace applications.
<u>
In LIB, the lithium ions move from the negatively charged electrode to the positively charged electrode during the discharge process and move in the reverse direction when the during the charging process.</u> The battery uses an intercalated lithium compound is used to form anode and graphite is used to form cathode.
<u>Thus, Lithium is oxidized/reduced in a lithium ion battery.</u>
Molecular compound consists of molecules whose formula represents the actual number of atoms bonded together in the molecule. While ionic compound are ions that gain or lose electrons resulting in a positive or negative charge.
C. the rock may have diferrent textures
Answer:The molar mass of atoms of an element is given by the standard relative atomic mass of the element multiplied by the molar mass constant, 1 × 10−3 kg/mol = 1 g/mol.
Explanation:
Groundwater is also one of our most important sources of water for irrigation from septic tanks and toxic chemicals from underground storage tanks and leaky landfills ... Drinking contaminated groundwater can have serious health effects. If there is a leak, these contaminants can eventually make their way down
