Combustion of hydrocarbons such as decane () produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide. 1. Write a balanced chemical equation, including physical state symbols, for the combustion of liquid decane into gaseous carbon dioxide and gaseous water. 2. Suppose of decane are burned in air at a pressure of exactly and a temperature of . Calculate the volume of carbon dioxide gas that is produced. Round your answer to significant digits.

C10H22(l) + 31/2 O2 (g)-----> 10CO2(g) + 11H2O(l)

V= 70.4L of CO2

Explanation:

Equation of the reaction is:

C10H22(l) + 31/2 O2 (g)-----> 10CO2(g) + 11H2O(l)

Number of moles of decane = mass/ molar mass

Molar mass of decane= 122gmol-1

n= 0.370×10^3g/122gmol-1= 3.0 moles

T= 13°C +273=286K

P= 1atm

R= 0.082 atmLK-1mol-1

From :

PV= nRT

V= nRT/P

V= 3.0×0.082×286/1

V= 70.4L of CO2

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
