Answer:
The water of crystallization of the intermediate analyte is 5.
Seeing as the question does not provide the value for weight of the salt on further heating (at 120° C), you can apply the steps in this explanation to attain that value.
Explanation:
XSO4.7H2O → XSO4 + 7H2O
8.1g 4.9g
8.1 - 4.9 = 3.9g of water evaporated
The ration of water to salt is:
XSO4 : H2O
grams : 4.9 3.2
moles: 72 + 32 + (16×2)=136 (1×2)+ 16= 18
0.036 0.178 (divide both sides by smallest value)
1 4.93
∴ <u>water of crystallization of intermediate is 5.</u>
Kinetic energy is an object in motion, potential energy is the potential for energy. Energy is the ability to make change, so kinetic energy is in the process of impacting something else.
Answer:
Yeild of CO2 is approximately 54g
Explanation:
Using reaction stoichiomety and coeeficients, and knowing O2 is limiting reactant, 54 g of CO2 is produced.
Answer:
Cyanohydrin
Explanation:
Step 1:
The nucleophilic C in the cyanide adds to the electrophilic C in the polar carbonyl group, electrons from the C=O move to the electronegative O creating an intermediate alkoxide
Step 2:
An acid/base reaction. Protonation of the alkoxide oxygen creates the cyanohydrin product.
