To insure complete clean combustion.
For a simple electro-magnet use a DC supply.
No. The supply is the number of similar products that are AVAILABLE at a given time and a given price. If the demand for the product at that price is less than the supply, not all the product will be bought (you will have some surplus product). In that case, "the number of similar products that will be bought at a given time and at a given price" represents the DEMAND (not the supply). It's called the law of supply and demand. Here's how it works. If the ratio of demand/supply is constant, then the price should remain constant. However, if that ratio increases, then the price should go up. If that ratio decreases, then the price should go down. If price goes down without changing the supply, then that will likely increase demand, changing the ratio of demand/supply, and resulting in the price increasing. If price goes up without changing supply, then that will likely result in reducing demand, resulting in changing the ratio of demand/supply, resulting in the price going down.

melting and burning
The combustion of a hydrocarbon produces carbon dioxide (CO2) and water (H2O) as byproducts. The chemical equation for the combustion of a hydrocarbon is typically hydrocarbon + oxygen -> carbon dioxide + water. Heat and light are often given off during this exothermic reaction.
calculate the number of moles of carbon and of the other and by number of moles you can proceed further. the next step is that you divide by the smallest ratio. hence obtaining your empirical formula.
The total supply of money in circulation in a given country's economy at a given time.

Hydrocarbons are compounds that has only carbon and hydrogen in it. Hydrocarbons such as methane, ethane, propane, regular gasoline etc., when burned in presence of oxygen, which is what essentially happens in our cars, gives off different gases with very little water. These gases given off by our cars, in other words the emission of gases due to burning of hydrocarbons can be called as hydrocarbon emission.
ac supply is given and then in the circuit rectifier converts ac to dc
a region of burning gases
Fossil fuel supplies are limited and not easily replaced. The principle of supply and demand suggests that as hydrocarbon supplies diminish, prices will rise. Therefore higher prices will lead to increased alternative, renewable energy supplies as previously uneconomic sources become sufficiently economical to exploit.
