Answer:
CHCl_3
Explanation:
An Arrhenius acid produces H^+ in solution. If we look at the options provided, all the other species are acids that contain at least one replaceable hydrogen ion hence they possess H^+ and can act as Arrhenius acids in solution.
However, CHCl_3 does not contain a replaceable hydrogen ion hence it does not function as an Arrhenius acid.
Answer : The mass of dog is, 14.7 kg
Solution :
Formula used for centripetal force is,
As we know that,
or,
So,
where,
= centripetal force = 40.3 N
m = mass of dog = ?
r = radius of path = 1.70 m
v = velocity or speed
= angular speed = 1.27 rad/s
Now put all the given values in the above formula, we get the centripetal force.
Thus, the mass of dog is, 14.7 kg
the answer is A because had this question before
Answer:
I think the correct answer for this is False.
Answer:
The information that can be used to determine which mixture has the higher proportion of KCl IS INFORMATION ABOUT THE MASS OF CHLORINE IN EACH MIXTURE, THIS INFORMATION CAN BE OBTAINED BY USING THE LAW OF DEFINITE PROPORTION.
Explanation:
The law of definite proportion states that the chemical composition by mass of a chemical compound is always constant. For instance, a chemical compound that is made up of two elements will always contain the same proportions of the constituent elements regardless of the quantity of chemical that was used.
Using the law of definite proportion, we can determine the proportion of sodium and chlorine in NaCl and the proportion of potassium and chlorine in KCl if the mass of chlorine that was used is known. Based on the results obtained, one can easily determine the mixtures that has higher proportion of KCl.
