Which of the following statements concerning green chemistry is incorrect? it is better to prevent waste than to treat or clean up waste after it is formed. chemical syntheses should be done at high enough temperatures to ensure harmful bacteria are destroyed. substances used in a chemical process should be chosen to minimize the potential for chemical accidents. raw materials should be renewable whenever technically and economically practical. synthetic methods should be designed to use and generate substances that possess little or no toxicity to human health or the environment.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

the answer is   c.) 1575 j.

explanation:

58750.08068 is the answer i think

the temperature of the gas, in k, not celsius.
