In the United States in 2004, there were approximately 41,492.000 people aged 15 to 24 and approximately 17,830,000 people aged 75 and up. Of the younger group, approximately people died of heart disease; of the older group, approximately 1,141,500 people died of heart disease. Based only on these figurescalculate the respective probabilities in 2004 that a person in each age group in the United States would have died of heart disease ; calculate each probability as a percent rounded to the nearest whole number. Provide a likely explanation for the difference in probability between age groups .

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.  

a is the answer to this question

explanation:

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
