Fields are used to connect tables in access, which means option a is the correct choice.
Design view allows you to build a table from scratch and set or change every available property for each field. You can also open existing tables in Design view and add, remove, or change fields. A "bound" shape is one this is without delay related to a records supply together with a desk or query, and may be used to enter, edit, or show records from that records supply. The relational version makes use of a group of tables to symbolize each information and the relationships amongst the ones information. Each desk has a couple of columns, and every column has a completely unique name.
Therefore, option a is the correct choice.

Answer:
The concentration of the original solution was 0.400 M
Explanation:
Step 1: Data given
Volume of the aqueous ethanol solution = 400 mL = 0.400 L
The solution was diluted to 4.00 L
The concentration of the diluted solution is 0.0400 M
Step 2: Calculate the concentration of the original solution
We use the dilution equation:
C1V1 = C2V2
⇒with C1 = the concentration of the initial solution = TO BE DETERMINED
⇒with V1 = the volume of the initial solution= 0.400 L
⇒with C2 = the concentration of the final solution= 0.0400 M
⇒with V2 = the volume of the final solution= 4.00 L
C1* 0.400 L = 0.0400 M * 4.00 L
C1 = (0.0400 M * 4.00L) / 0.400 L
C1 = 0.400 M
The concentration of the original solution was 0.400 M
Answer:
0.0794 L
Explanation:
An experiment requires 62.7 g of ethyl alcohol. The density of ethyl alcohol is 0.790 g/mL. The volume, in milliliters, corresponding to 62.7 g of ethyl alcohol is:
62.7 g × (1 mL/0.790 g) = 79.4 mL
1 liter is equal to 1000 milliliters. The volume, in liters, corresponding to 79.4 mL is:
79.4 mL × (1 L/ 1000 mL) = 0.0794 L
Answer:
50 I think not 100% sure
Explanation:
Because you just do 10*5 which equals 50.
