Answer:
NO, they are not the same compound
Explanation:
Given that;
Compound A melts at 220.5 °C - 222.1 °C; &
Compound B melts at 221.2 °C - 223.4 °C
It is seen from above that there is little difference in the melting point of Compound A and B. This little difference can be as a result of factors associated when carrying the melting process or because different methods were employed in the establishing their melting points.
Also, we were told that when they were both mixed together , the mixture of compound A and B melts at 216.4 °C - 224.6 °C.
This statement has largely indicated that both compounds are not the same at all, because if they were, the mixture of compound A and B melting point must be identical to one of the individual compound's melting point either from compound A or from compound B.
Answer:
The dose of Mylanta 30 cc will decrease the absorption of the Tetracycline 250mg. The consequence of this is that, the patient will not be receiving a therapeutic dosage of the Tetracycline 250mg. Also, the Antacid should not be given together with any other drug, especially antibiotics.
An easy way to do it is to convert the percentage to a decimal, in this case, .32
Then, multiply that by the amount of people.
An equation would be,
Hope this helped :)
Answer: 1. 
increases.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
For the given equation:
If the concentration of 
is increased , according to the Le-Chatlier's principle, the reaction has to shift to right or forward direction. In order to do that the concentration of products has to increase.
Thus the concentration of increases.
