could you PLEASE help me with this two exercises

creating 1-2 pages on VISIO please

Draw an E-R Diagram for each of the following problem statements using Visio. Put each ERD on a new page of the same Visio document, so that your document has Page-1, Page-2. Name your Visio document LASTNAME_Many2Many and submit to D2L. Problem 1: A laboratory has several chemists who may use certain pieces of equipment. Each piece of equipment may be used by several chemists, or it may be idle, that is, not in use by anyone. Since this is a many-to-many relationship, there is an associative entity CHEMIST-EQUIP, that connects CHEMIST and EQUIPMENT. Attributes of chemist include chemist id, name and phone number. Equipment has the attributes serial number and cost. The organization wishes to record an Assign_Date, i.e. the particular date when a given piece of equipment was assigned to a particular chemist. (Hint Assign_date is an attribute of the Associative Entity CHEMIST-EQUIP.) Problem 2: The entity type STUDENT represents any university student. ACTIVITY represents some campusbased activity in which the student may participate. A student may participate in zero or more activities, and an activity may have zero or more students participating in it. PARTICIPATION is the associative entity that represents one student participating in one particular activity. No years is an attribute of PARTICIPATION. Each student has a unique ID and name; and an activity has a unique ID and activity name
