There will be four hydrogen atom at the product
Answer:
A
Explanation:
A common example of heterogeneous catalysis is the hydrogenation reaction of simple alkenes. The conversion of ethene (C2H4) to ethane (C2H6) can be performed with hydrogen gas in the presence of a metal catalyst such as palladium (“Conversion of Ethene to Ethane with Hydrogen and a Metal Catalyst”).
Work is done when force is applied to an object and the object moved from one its distance ( one place to another )
so Work = Force * Distance
if force is 300N and distance is 100m
then Work = 300 * 100 Nm( newton meter) = 30000J
( Joule = newton meter)
Answer:
Explanation:
a) 4-nitrobenzoic acid pKa= 3.41
benzoic acid pKa= 4.19
4-chlorobenzoic acid pKa= 3.98
b) benzoic acid pKa= 4.19
cyclohexanol pKa= 18.0
phenol pKa= 9.95
c) 4-Nitrobenzoic acid pKa= 3.41
4-nitrophenol pKa= 7.15
4-nitrophenylacetic acid pKa= 3.85
Answer:
B. 288. G
Explanation:
Moles of Al :
Given, Mass of Al = 20.4 g
Molar mass of Al = 26.9815 g/mol
The formula for the calculation of moles is shown below:
Thus,
The reaction between Al and I is shown below as:
2Al + 3I₂ ⇒ 2AlI₃
2 moles of aluminium react with 3 moles of iodine
1 mole of aluminium react with 3/2 moles of iodine
0.7561 moles of aluminium react with (3/2)*0.7561 moles of iodine
Moles of Iodine = 1.13415 moles
Molar mass of NaOH = 253.8089 g/mol
The formula for the calculation of moles is shown below:
Thus,
Mass of Iodine = 288 g
