Answer:
Fire's basic combustion equation is: fuel + oxygen —> carbon dioxide + water, a line many of us had drummed into us by school teachers. However, combustion reactions do not proceed directly from oxygen to carbon dioxide.

Answer:
The correct option is: the precipitation of acidic compounds formed when components of air pollution interact with other components in the air.
Explanation:
<u>Acid rain</u> is a form of precipitation which is usually <u>acidic in nature</u>. The acidic nature of rain is due to the reaction of <u>water molecules with sulfur dioxide, carbon dioxide and nitrogen oxide present in the air, to produce acids.</u>
There are many adverse effects of acid rain, some of them are: effect on water bodies, forests, living organisms, corrosion of structures made of steel and weathering of buildings.
The elemental classification for oxygen would be non-metal. It is located in period number 2 and group number 16. It has an atomic number of 8. At room temperature, it exists as a gas. Hope this answers the question. Have a nice day.
Answer:
synthesis
Explanation:
Step 1: Data given
Decomposition = a reaction in which a compound breaks down into two or more simpler substances. The general form of a decomposition reaction is:
AB→A+B
Synthesis = A reaction that occurs when one or more compounds combines to form a complex compound:
A + B → AB
Double replacement: a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds.
The general form of a double-replacement reaction is:
AB+CD→AD+BC
Combustion reaction = a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve O2 as one reactant.
single replacement = A reaction in which one element replaces a similar element in a compound. For example, a metal replaces an other metal.
The general form of a single-replacement (also called single-displacement) reaction is:
A+BC→AC+B
The reaction Na2O + H2O → 2NaOH
⇒ Does not involve O2 = NOT a combustion reaction
⇒ There is no replacement of 1 or more elements,.. This reaction is not a single replacement, neither a double replacement.
⇒ A compound does not break down into smaller substances = NOT a decomposition
The compounds starts from 2 simple substance to form a more compelx compound = <u>a synthesis
</u>
Volume of CO₂ obtained : 13 L
<h3>Further explanation</h3>
Reaction
C₂H₅OH + 3 O₂ ⇒ 2 CO₂ + 3 H₂0 + 8842 Joules
moles of ethanol=0.28
From equation, mol ratio ethanol : CO₂ = 1 : 2, so mol CO₂ :
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
Then volume of CO₂ :
