(A,B)(C) P-Br(D) P-Cl...... (C,D)
Answer:
See explanation
Explanation:
In the section A,B
C triple bond O has a higher bond energy. A triple bond is shorter and more difficult to break hence they have a higher bond energy.
For the same reason in the C,D section; C triple bond N has a higher bond energy.
In the next section, the higher the bond order the shorter the bond. Hence C triple bond C is the shortest in the A,B section while C triple bond O is the shortest in the C,D section. Both have a bond order of 3.
In the A,B section; I is larger than Br hence H-Br has the shortest bond length.
In the C,D section; Br is larger than Cl hence P-Cl has the shortest bond length.
In the ground state atoms of the elements in group 15 of the periodic table all have the same number of

a 30-n net force on a skater produces an acceleration of 0.6 m/s2. what is the mass of the skater
Answer:
The answer is 50 kgExplanation:
The mass of the skater can be found by using the formula
[tex]m = \frac{f}{a} \\ [/tex]
f is the force
a is the acceleration
From the question we have
[tex]m = \frac{30}{0.6} \\ [/tex]
We have the final answer as
50 kgHope this helps you

Someone thought there was water in Beaker C. He drank some and quickly spat out.He said that it was salty. Explain why this happened.
Answer:
He assumed wrongly
Explanation:
It happened this way because the person assumed wrongly.
Most other compounds have the same physical appearance as water especially when in liquid form.
This can be a very tricky one in the laboratory. The sense of taste is not the best way to fathom what a particular compound is made up of. This is the reason why this student or person faced this sort of problem. Water has different properties that can be tested for using simple techniques in the laboratory.What quantity is measured in g/dm^3

Atoms are like letters of the alphabet and the compounds are like they make are like words this sentence:
Ed helper question
Explanation:
This is very correct atoms can be viewed as elements and compounds the words that are made from them.
Elements are distinct substances that cannot be split up into simpler substances. Such substances are only made up of one atom. This can pictured as alphabets also. They are the fundamental units by which words are formed.Compounds are substances composed of two or more kinds of atoms joined together in a definite grouping. They are like words.
