Percentage error = ((12.7/11.5)-100%)x 100% = 10.4% (3 s.f.)

Since the measured yield exceeds the theoretical one, this means the error is in excess. Divide the measured yield by the theoretical yield and subtract 100% to find the difference, then multiply by 100% to find the percentage.

Sav [38]

Answer:

a, b and c

Explanation:

To calculate molarity the number of moles and volume in dm3 is needed. So with the mass and molar mass the number of moles can be gotten and hence the molarity when dividing the number of moles by the volume in dm3.

Sun.<br> What planet is famous for the beautiful rings that surround it?

laiz [17]

Answer:

Saturn. Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine times that of Earth. It only has one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive.

What is the approximate bond angle around the central carbon atom in acrolein?

Pavlova-9 [17]

Hello!

The approximate bond angle around the central carbon atom in acrolein is 120°

The structure of acrolein is shown in the figure below. From the structure, we can deduce that the central carbon atom is in an sp2 hybridization (Atoms with a double bond hybridize in an sp2 fashion).

Atoms with sp2 hybridization have trigonal planar geometry, in this kind of hybridization, bonds are oriented the farthest away possible from each other, to minimize overlapping and the angle that allows that is 120°.

Have a nice day!
