The forces in NH3 includes the vanderwaals force which will always be present and hydrogen bonding due to the electronegativity of N as compared to H. When it is in solution, there will be ionic interactions because there will be some NH4+ ions formed.
In viewing a chemical equation,we <span>determine the ratios that relate reactants and products </span>from the coefficients of the reactants and products .
Answer:
Le Chatelier's principle can be applied in explaining the results
Explanation:
According to Le Chatelier's principle, when a constraint such as a change in concentration in this case is imposed on a chemical system in equilibrium, the system will adjust itself in such a way as to annul the constraint imposed.
Hence, when the color of the solution was more like that of the control, the reaction would shift towards the left. Similarly, when the color was more like it was towards the reactant, the reaction would shift towards the right.
If we were to prepare calcium oxalate, we should prepare it in a base solution. This is because when the base was added to calcium oxalate, it did not form any precipitate but when an acid was added to the calcium oxalate, it formed a precipitate.
Answer:
50m/s
Explanation:
The formula for calculating speed of wave in relation to frequency and wavelength is
C=λf
Where c is the speed of the wag
λ is the wavelength which is 1m
f is the frequency which is 50Hz
From the formulas,
C= 50X1
C= 50m/s

I hope this helps. I'm more than 100% sure that all the answers except for number 7 are correct. I knew all of them off the top of my head except for this one. I hope the other answer has the correct answer for that one. Good luck and have a great day.
