Explanation:
the structural formula of butyl pentyl ether
Answer: i believe it is
602,000,000,000,000,000,000,000 atoms
Explanation:
6.02×1023 atoms/mole
To solve this problem we just need to use the rule of three:
150g..................395.1J
450g................xJ
x = 450*395.1/150 = 1185,3J
450.0 g of the substance completely reacted with oxygen will produce 1.1853 kJ(<span>kiloJoule</span>)
