Silver is A precious shiny grayish-white metal, the chemical element of atomic number 47. Silver is sometimes found in nature in metallic form. It forms a sulfide mineral Ag 2 S called acanthite. Mineral forms of silver include sulfides formed with antimony called Stephanite, miargyrite and pyrargyrite. Silver is a naturally occurring element on the periodic table and can be found in natural deposits throughout the world. As such, it was discovered in 5000 BC, but not invented, by people.

Why do cells use fat and starch for long term energy storage instead of ATP molescules?

IceJOKER [234]

ADP is like an uncharged battery. ATP is like a charged battery, ready to provide energy to do work in the cell. The charging of ADP into ATP takes place in the mitochondria. Fat and starch are stable (last a long time) whereas ATP goes dead too quick and will need to be recharged.

glucose is a carbon chain molecule (sugar). When the bonds in the chain are broken, energy is released. That energy is used to turn ADP into ATP. Glucose is the "electricity" used to charge the battery.

Consider four different samples: aqueous LiF, molten LiF, aqueous AgF, and molten AgF. Current run through each sample produces

meriva

Answer:

Molten LiF forms solid lithium

Aqueous AgF forms solid silver

Aqueous LiF forms hydrogen gas.

Explanation:

Aqueous solution of $LiF$ has water molecule, there will be competing will be two competing cations for reduction, while $Li^{+}(aq)$ and $H^{+}(aq)$ .However the reduction potential of $H^{+}(aq)$ is more than that of the $Li^{+}(aq)$ . Hence, $H^{+}(aq)$ reduced to hydrogen gas.

Molten $LiF$ has only solid form of $LiF$ and $Li^{+}(aq)$ reduced to form $Li$ solid.

An aqueous form of $AgF$ contains water molecules.there will be competing will be two competing cations for reduction, while $Ag^{3+}(aq)$ and $H^{+}(aq)$ .However the reduction potential of $Ag^{3+}(aq)$ is more than that of the $H^{+}(aq)$ . Hence, $Ag^{3+}(aq)$ reduced to solid silver.
