• Ionic bonds form between and . • In naming simple ionic compounds, the is always first, the second (e. g., sodium chloride). • Ionic compounds dissolve easily in water and other polar solvents. • In solution, ionic compounds easily dissolve. • Ionic compounds tend to form with melting temperatures.
Naming Ionic Compounds
• Write the first and the second • Use to indicate the number of atoms of each type present in the compound
• No prefixes
• Change the syllable of the to say

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
