On page 2, insert a Dropped Drop Cap at the beginning of the first body paragraph ("At Your Service is a digital tool…") to mark the beginning of the body text.Provide more detailed information as follows:Find the sentence "Customers prefer using…exchanging email messages."After the period at the end of the sentence, insert a footnote with the following text: About 55 percent of our customers prefer live chat.Insert a picture as follows to illustrate the options in the At Your Service app:Insert the picture Support_WD19_CS1-4_Icons.png in the blank paragraph after step 2 in the "Getting Started with At Your Service" section.Resize the picture to a width of 2".Add visual interest to the "Chatting with Customers" section as follows:To the left of the "Customers can use…conduct the dialogue." paragraph, insert a Speech Bubble: Rectangle with Corners Rounded shape from the Callouts section of the Shapes gallery. On page 1, rotate the picture to the right by 90° so that it has the correct orientation.Change the theme colors of the document to Paper to coordinate with the company colors.

The positive slope of metal oxides shows that their stabilities decrease with increase in temperature.The Ellingham diagram is the plot of free energy change ΔG° against temperature for the reaction of metal and other elements with one mole of gaseous oxygen at 1 atmosphere. The graphical representation showing the variation of Gibbs energy with increase of temperature for the formation of oxide (oxidation) is known as Ellingham diagram.
