Answer:
The correct answer is c. the acetate ion acts as a Bronsted-Lowry base in a reaction with water.
Explanation:
Sodium acetate (NaCH₃COO) dissociates in water to give Na⁺ and CH₃COO⁻ ions as follows:
NaCH₃COO(s) → Na⁺(aq) + CH₃COO⁻(aq)
The acetate ion (CH₃COO⁻) is the conjugated base of acetic acid (CH₃COOH). Acetic acid is a weak acid, so the acetate ion will try to regenerate the weak acid. For this, it will acept a proton (acting as a Bronsted-Lowry base) from water to form acetic acid. As result, OH⁻ is released and the solution turns basic:
CH₃COO⁻(aq) + H₂O(l) ⇄ CH₃COOH(aq) + OH⁻(aq)
Answer:
11.3 g.
Explanation:
Hello there!
In this case, since the combustion of butane is:
Thus, since there is a 1:5 mole ratio between butane and water, we obtain the following mass of water:
Therefore, the resulting mass of water is:
Best regards!
Answer:
A turbine takes the kinetic energy of a moving fluid, air in this case, and converts it to a rotary motion.

Answer:
Explanation:
In the peak stage of a flood where it current is very high,there is much deposition of sediment dumped into the stream by mainly overland flow and gully erosion.This leads to huge sediment deposition on the stream bed.
As the flood 's current reduces,competence and capacity reduces and sediments are deposited.
Answer:
68133080.02 g
Explanation:
I believe that the question is to find the mass of air in the room and not the molar mass of air since the molar mass of air was already given in the question as 28.97 g/mol.
Now, if 1 mole of a gas occupies 22.4 L
x moles of air occupies 52,681,428.8 Liters
x = 1 * 52,681,428.8 /22.4
x = 2351849.5 moles of air
Now, number of moles = mass/ molar mass
but molar mass = 28.97 g/mol
2351849.5 = mass/28.97
mass = 2351849.5 * 28.97
mass = 68133080.02 g
