P1/T1 = P2/T2

125⁰C = 398.15 k

182⁰C = 455.15 k

1.22/398.15 = p2/455.15


p2= 1.39atm

the pressure of the gas be after the temperature change is 1.39 atm

Answer:

1.4 atm

Explanation:

According to Gay Lussac’s law, the pressure of gas is inversely proportional t its temperature, when the volume is constant

Initial temperature = 125 + 273 = 398 K

Final temperature = 182 + 273 = 455 K

Initial pressure = 1.22 atm

\frac{P1}{T1} = \frac{P2}{T2}

1.22 atm / 398 K = P₂/ 455 K

P₂ = \frac{1.22 atm x 455 K}{398 K} = 1.4 atm

What is meant by the term sensitivity in Analytical Chemistry? (a) The term refers to the limit at which the absorption instrume
ivolga24 [154]

The term sensitivity in Analytical Chemistry is "the slope of the calibration curve or a function of analyte concentration or amount".

<u>Answer:</u> Option B

<u>Explanation:</u>

In a sample, the little amounts of substances can be accurately evaluated by a method is termed as "Analytical sensitivity". This detect a target analyte like an antibody or antigen, process is considered as potential of a test to and generally demonstrated as the analyte's minimum detectable concentration.

The acceptable diagnostic sensitivity is not guaranteed by high analytical sensitivity. The percentage of individuals who have a given disarray who are identified by the method as positive for the disarray is known as "Diagnostic sensitivity".

Balance the following chemical equation Na + Cl2 -&gt; NaCl and explain how the balanced equation models the law of conservation
Alexus [3.1K]

Answer:

2 Na + 1 Cl2 -> 2 NaCl

Explanation:

The answer is really simple, because if you have 1 nonmetal element that has a subscript of 2, you need to multiply the product and the first reactant by 2 to balance it.
