The conclusion cannot be validated because other factors such as the amount of sunlight water location also play a vital role in germinate
Answer: The correct answer is Option a and d.
Explanation: Both the salts are ionic in nature because when dissolved in water, they dissociate into their respective ions.
Ionic compounds are held together by ionic bond. They are neutral compounds as both positive and negative charges neutralize each other. These compounds are also good conductors of electricity because of the presence of ions.
As both the salts have different molecular formula, both of them will have different crystal lattice system and hence, different crystal lattice energy.
From the above information, the correct options are option a and option d.
Answer:- 5.91%
Solution:- The given balanced equation is:
From given moles of zinc iodide we calculate the moles of zinc carbonate using mol ratio from the balanced equation and the moles are converted to grams on multiplying by molar mass.
=
Molar mass of zinc carbonate is 125.38 gram per mol. Let's multiply the moles by molar mass to get the theoretical yield:
=
theoretical yield is 213.15 g and the actual yield is given as 12.6 g.
percent yield =
percent yield =
= 5.91%
The percent yield of zinc carbonate is 5.91%.
Answer:
double displacement reaction also neutralization reaction cause of acid and base
<h3><u>Answer</u>;</h3>
pH = 3.03
<h3><u>Explanation</u>;</h3>
NaCl is a neutral salt and does not affect the pH.
moles HCl = g HCl / MM
= 16.5 / 36.5
= 0.452 equivalent to moles H+
Molarity H+ = moles H+ / L
= 0.452 / 482
= 0.000938 M
Hence; pH = -log[H+]
= -log(0.000938)
= 3.03
