Answer: Option (A) is the correct answer.

Explanation:

A pH strip is a strip which helps in determining whether a solution is acidic or basic in nature.

That is, if a solution is acidic in nature then a pH strip will change from blue to red. Whereas when a solution is basic in nature then a pH strip will change from red to blue.

Thus, we can conclude that statement molecules in the paper react differently with hydronium and hydroxide ions, best describes how a pH test strip works.

Molecules in the paper react differently with Hydronium and Hydroxide.

pH paper deals with acidity and basicity of something. You are correct in thinking that A is the answer. Always go with your gut. don't be like me when I was in college who always second guessed my answers. Good luck with chemistry.

Whitney's tidal volume, which is the volume of air that she inhales and exhales, was 0.56 L . Her tidal volume was measured at a

ipn [44]

Given:

Volume of air inhaled V = 0.56 L

Temperature T = 37 C = 37 +273 = 310 K

Pressure P = 744 mmHg = 744/760 = 0.979 atm

% N2 in air = 78%

To determine:

The moles of N2 inhaled in one breath

Explanation:

Step 1: Calculate the moles of air inhales

Based on the ideal gas law:

PV = nRT

where P = pressure, T = temperature, V = volume, n = # moles

R = gas constant = 0.0821 L atm/mol-K

n = PV/RT = 0.979 * 0.56/0.0821*310 = 0.0215 moles of air

Step 2: Calculate the moles of N2

It is given that air contains 78% N2

Therefore:

moles of N2 = 0.0215 * 78/100 = 0.0168 moles

Ans: moles of N2 = 0.0168

A spectrophotometer measures the transmittance or the absorbance, or both, of a particular wavelength of light after it has pass

Taya2010 [7]

Answer:

b. The transmittance of the cuvette must be measured in the same place each time.

Explanation:

When using a spectrophotometer, light passes not only through the liquid sample, it also passes through the cuvette. This means that each time a reading is made, you not only measure the transmittance/absorbance of the sample, but of the cuvette as well.

For this reason it's important that the reading of the cuvette's absorbance remains the same through all the process, so the answer is b), because different faces of the cuvette may have different absorbances.
