COS, or carbonyl sulfide, is shown in the attached picture as a Lewis structure. As you can see, carbon and sulfur are connected through a double bond. There is an empirical data for bond energies of specific bonds. Refer to this site: http://www.wiredchemist.com/chemistry/data/bond_energies_lengths.html. If you find C=S, the bond energy is equal to
<em>573 kJ/mol</em>.
Answer : The correct option is, B) 200 N to the left
Explanation :
If the two forces are acting on an object in the opposite directions and they do not exactly cancel each other then the net force is calculated by the difference in the forces.
The force act on an object in the left side are greater than the right side. So, the net force is 200 N to the left.
Therefore, the correct option is, B) 200 N to the left
Answer:
a-Interatomic bonds
Explanation:
First of all, it is not a force. Let alone be molecular force.
The question is incomplete, the complete question is;
To make a table of the elements, dimitri Mendeleev sorted the elements according to their?
Answer:
Atomic weights
Explanation:
Dimitri Medeleeve is a Russian scientist who worked assiduously on the project of developing a system of classifying all the elements. His periodic table was filled with spaces as many atoms weren't yet discovered. 'Eka' prefix was used to name some elements whose properties closely resembled that of their predecessors in Mendeleev's system of classification.
The dependence of the atomic properties on the weight of the atom was the basis for Mendeleeves' original classification. According to Medeleeve, elements having similar chemical properties are also expected to have similar atomic weights and their atomic weights was found to increase regularly.
The Mendeleeve concept of periodic arrangement of elements is the closest precursor of the modern periodic table as it is used in chemistry. Mendeleev arranged the elements in order of increasing relative atomic mass .
Answer:
A study performed by Dr. Birdie signified that the number of songbirds in her yard enhanced because of a modified source of food.
Explanation:
A scientific claim refers to a claim, which is postulated by a scientist because of the outcome, which he or she has attained in the research that has been conducted. In the given case, it can be witnessed that Dr. Birdie experience influx of songbirds to her yard as an outcome of the dried apple and the raisin, which she has supplemented in the diet of the birds.
