The appropriate response is amide. Amides are generally viewed as subordinates of carboxylic acids in which the hydroxyl bunch has been supplanted by an amine or smelling salts. The solitary combine of electrons on the nitrogen is delocalized into the carbonyl, along these lines framing an incomplete twofold bond amongst N and the carbonyl carbon.
Answer:
d.- 0.045 M Al2(SO4)3
Explanation:
From the ionic salts that are presented, when they dissolved in water, the ions are going to be separated. From the list above, the aluminum is the metal that posses the highest electrical conductivity.
The second ion that can conduct electrical charge is the sodium. This ability is due to the atomic structure, the electrons are easy to be be apart from the aluminum that other metals.
Potential energy (Pe) = m*g*h
m = 4 kg
g = 10 m/s²
h = 3 m
And now:
Pe = 4*10*3
Pe = 120 Joules ou J
Answer: A) 9.25 KJ.
B) - 148.296 KJ.
C) 296 KJ/mol.
Explanation:
For the reaction: S(s) + O2(g) → SO2(g), ΔH = -296 KJ/mol
A) The number of moles in 1.00 g of S is
n = mass/atomic mass = (1.00 g) / (32.00 g/mol) = 0.03125 mole
So, the quantity of heat when 1.00 g of sulfur burned in oxygen = ΔH of the reaction for 1.0 mole x no. of moles = (-296 KJ/mol) x (0.03125 mole) = 9.25 KJ.
B) The quantity of heat released when 0.501 mole of sulfur is burned in air = ΔH of the reaction for 1.0 mole x no. of moles = (-296 KJ/mol) x (0.501 mol) = - 148.296 KJ.
C) The quantity of energy is required to break up 1.0 mole of SO2(g) into its constituent elements = 296 KJ/mol.
It is the same that the amount of energy released when 1.0 mole of S is burned in oxygen.
The process of formation (burning of S) is exothermic.
On the other hand, the reverse operation (breakdown) must be endothermic (and therefore a positive energy change) = 296 KJ/mol.
<span>2H2 + O2 ---> 2H2O this is it i think<??</span>
