The material, which does not melt at any temperature is WOOD.
Wood is made up of many substances including lignin, water, cellulose and other organic materials. When wood is heated, it normally oxidizes in the presence of oxygen before it has the chance to melt. The physical structure of the wood is typically destroyed during this process and the original material can not be obtain again.This irreversible breakdown of wood makes it impossible for wood to melt. <span />
Answer:
[He]2p6
Explanation:
Fluorine has an atomoc number of 9 which means 9 electrons with the electon configuration:[He]2p5,However,when it becomes Fluoride ion,it gains one electron to complete its outermost shell to obtain an octet configuration and becomes [He]2p6.
Answer:
- Current market value of silver produced in the experiment = $0.2763
- Check Explanation for the appearance of leftover copper wire used in the experiment.
Explanation:
Price of Silver on today's market = $15.34 per troy ounce
Amount of Silver produced in the experiment = 0.56 g
31.1 g = 1 troy ounce
0.56 g = (0.56/31.1) = 0.01801 troy ounce
1 troy ounce = $15.34
0.01801 troy ounce = 0.01801 × $15.34 = $0.2763
The original reaction to extract the silver is one between Copper metal and the Silver Nitrate.
The Copper metal dissolves in the Silver Nitrate to give Copper Nitrate thereby displacing the Silver ion to become silver metal which we just valued above. But copper nitrate is a blue solution, So, it is a good estimate to say that the entire solution changed to that blue colour and the appearance of the leftover copper metal is colour blue. The silver metal forms as fractal-like crystals on this leftover copper.
Hope this Helps!!!
Answer:
The voltage or potential difference
Explanation:
What makes current flow in a circuit is the voltage or the potential difference.
This force is supplied by the battery or the mains electrical circuit.
- Every circuit requires the voltage to drive current through
- When a circuit is complete, the battery is able to overcome any resistance by the generating enough voltage which is the force to drive the current through.
