Answer:
Explanation:
Hello,
In this case, the undergoing chemical reaction is shown below:
Thus, we obtain 0.0471 g of lead (II) sulfate, the iodide ions in the original solution are computed below by stoichiometry, taking into account that into 1 mole of lead (II) iodide there are 2 moles of iodide ions:
Best regards.
Explanation:
<h2>(a).</h2>
The density of a substance can be found by using the formula
From the question
mass of metal = 14 g
volume = 2.98 mL = 2.98 cm³
It's density is
We have the answer as
4.70 g/cm³
<h2>(b).</h2>
The metal is not copper since it's density is less than that of copper.
Hope this helps you
Answer:
See the answer below, please.
Explanation:
The equilibrium constant is defined as the relationship between products and reagents, each one elevated to their stoichiometric coefficients, in that of the given equation, the Kc is:
Kc= (NH4)^1/ (NH3)^1 x (HI)^1
NH4= products
NH3 and HI = reagents
