Some of the scientific questions that may be answered through the experiment are:

(1) What are the physical changes that may occur in the solution or the indicator when added with acidic/basic solution?

(2) How much of the indicator is needed in order to bring about a significant physical change in the solution to identify its H+ concentration?

Answer:

Sample response: How is pH used to determine if a solution is acidic or basic?

Explanation:

What did you include in your question? Check all that apply.

focuses on the pH scale

suggests a way to measure how acidic or basic a solution can be

allows for observations and an opportunity to look at pH quantitatively and qualitatively

navik [9.2K]

Answer:

A gas made up of homonuclear diatomic molecules escapes through a pinhole .533 times as fast as Ne gas. Write the chemical formula of the gas.

Molar mass of Ne gas is 39.1 g/mol

.533= sqrt(39.1/x)

Sq (0.533) = 20.18/x

0.284 = 20.18/x

x = 71.034 g/mol

Where the chlorine has a molar mass of = 35.5g and molar mass of Cl2 gas = 2 × 35.5 = 71 g/mol

Explanation:

Graham's law: Rate1/Rate2 = sqrt(M2/M1) where M is the molar mass

Thus we have (Rate of x)/(Rate of Ne) = sqrt((Molar mass of Ne)/(Molar mass of x))

From the question (Rate of x)/(Rate of Ne) =0.533

and sqrt((Molar mass of Ne)/(Molar mass of x)) = sqrt(39.1/(Molar mass of x))

.533/1= sqrt(39.1/x)

Sq (0.533) = 20.18/x

0.284 = 20.18/x

x = 71.034 g/mol

Hence a compatible gas is chlorine Cl2 with molar mass of

71 g/mol
