How much heat is released when 47.50 g of CH4 (g) is burned in excess oxygen gas to produce carbon dioxide and water?

Elina [12.6K]

Answer:

= 2113.44 kJ

Explanation:

When 1 mole of CH4 (g) burns in excess oxygen -714.0 kJ of heat is released.

For 47.50 g;

molar mass of CH4 = 16.042 g/mol

Number of moles of CH4

= 47.5 g /16.042 g/mol

= 2.96 moles

Therefore;

1 mole = -714.0 kJ

Heat change for 2.96 moles

= 2.96 moles × -714.0 kJ

= 2113.44 kJ

(b) Draw the structure of the products when cyclopentene is reacted with:

oee [108]

Answer:

See explanation and image attached

Explanation:

When an alkene is reacted with cold, dilute and alkaline KMnO4, the product of the reaction is a 1,2-diol (vicinal diol). The products exhibit a “syn” stereochemistry with the addition of the two -OH groups to the same side of the alkene.

The reaction of cyclopentene with cold, dilute, alkaline KMnO4 is shown in the image attached.
