Explanation:
acetic acid Dissociation:
Dissociation constant of the Ka:
using the ICE table:
x is negligible compared to Ka.
From the ICE table,
Answer:
Yes, it does not have chemical properties.
Explanation:
Helium, as an inert element, cannot rearrange its electrons to form another chemical substances with another element, like a combustion or an acidification, even though it can form nuclear reactions, these are not considered chemical reactions, because it does not involve a rearrangement of the electrons but changes the nucleus of the element giving another elements.
The mass of Ca(CN)2 : 92,11 g/mol
<h3>Further explanation</h3>
Given
0.0321 moles of Ca(CN)2
Required
The mass
Solution
The mole is the number of particles contained in a substance
1 mol = 6.02.10²³
Moles can also be determined from the amount of substance mass and its molar mass
mol(n) = mass(m) : MW(molecular weight)
Input the value :
mass = mol x MW Ca (CN)2
mass = 0.0321 x 92,11 g/mol
mass = 2.957 g
