In order to calculate the final volume of the gas, we may apply Charles Law, which states that for a fixed amount of gas subject to a fixed amount of pressure, the volume and temperature of a gas are directly proportional. This is:
V/T = constant
Using this equation,
5/298 = V/278
V = 4.66 L
The final volume of the gas is 4.66 liters

Answer:
Sample A
Explanation:
Molarity of a solution can be calculated using the formula:
Molarity = number of moles (mol) ÷ volume (vol)
For Sample A:
V = 300ml = 300/1000 = 0.3 L
Molarity = 1M
n = number of moles (mol)
1 = n/0.3
n = 0.3moles
For Sample B:
V = 145 mL = 145/1000 = 0.145L
Molarity = 1.5 M
n = number of moles
1.5 = n/0.145
n = 1.5 × 0.145
n = 0.22 moles
Based on the above results (moles), sample A with 0.3 moles contains the larger concentration of sodium chloride.
Answer:
would be the conjugate base in this reaction according to the Bronsted-Lowry acid-and-base theory.
Explanation:
Among the reactants, the Bronsted-Lowry acid is the species that supplies protons . The Bronsted-Lowry base would be the species that accept the protons.
On the product side of the equation, the BL-acid donates a proton to produce the conjugate base. The BL-base accepts a proton to produce the conjugate acid.
In this case, each molecule donates a proton to form one ion. Hence,
Each molecule would accept a proton to produce an ion. Hence,
