Sodium chloride has a high meltint point because of the strong electrostatic attraction between its positive and negative ions.
Hello!
Graphs are used to understand an object's motion because they can show the exact location of the object at any given moment.
This is done with the help of a reference system. The most common reference system is the Cartesian coordinate system, which describes the location of an object through a set of 2 or 3 coordinates (depending if the system is in 2D or 3D).
Studying graphs of movement, we can know if the movement is cyclical, or the direction of the movement, determine tendencies and overall getting an unambiguous and precise understanding of the motion.
Have a good day!
Answer:
Student's percent yield = 94.6%
Explanation:
Given:
Estimated yield of BaSO₄(s) = 1.352 grams
Actual yield = 1.279 grams
Find:
Student's percent yield = ?
Computation:
Student's percent yield = [Actual yield / Estimated yield of BaSO₄(s)]100
Student's percent yield = ( 1.279 grams / 1.352 grams)100
Student's percent yield = (0.946)100
Student's percent yield = 94.6%
Answer: has a double bond
Explanation: O2 has a double bond in its normal form. That is O=O. There are no unpaired electrons in this case are there since there are 2 lone pairs on each oxygen.
Answer: A. Carbonyl Group
Explanation:
A carbonyl group, is a functional group made-up of a carbon atom double- bonded to oxygen in organic chemistry. Basic carbonyl groups are ; Aldehydes and Ketones.
