For a candle to burn, it requires a spark, which provides the activation energy for the oxidation reaction of the hydrocarbon making the candle.
It also requires oxygen to facilitate the oxidation of the hydrocarbon.
Therefore the two main requirements of combustion of a candle are oxygen and a spark (or an initial flame)
42700 milliliters would be the answer...
Hope this helps!
NaCl would form because it’s a single replacement reaction
Answer:
I think that the statement is relative to speed because it is saying km per second.
A) CH4
In general, methane reactions are difficult to control. Partial oxidation to methanol, for example, is a rather difficult reaction because the chemical reactions that occur continue to form carbon dioxide and water even though the amount of oxygen available is insufficient.
<h2>Further explanation
</h2>
Methane is the simplest hydrocarbon in the form of gas with the chemical formula CH4. Pure methane does not smell, but if used for commercial purposes, a bit of sulfur is usually added to detect leaks that might occur.
Methane is a greenhouse gas. Methane is used in chemical industrial processes and can be transported as frozen liquids (liquefied natural gas, or LNG).
Methane is a major component of natural gas, around 87% of volume.
Methane is not toxic, but is highly flammable and can cause explosions when mixed with air.
