Your answer would be, Gas atoms subjected to the electricity emit bright lines of light.
Hop that helps!!!
Answer:
B. primary; secondary
Explanation:
Small changes in primary structure can result in large changes in protein shape and function. Secondary structure describes regions where the polypeptide is folded into localized shapes. There are two types of secondary structure (alpha helix and Beta pleated sheet).
Answer:
accuracy
Explanation:
Accuracy refers to the closeness of the accepted value
Precision refers to the closeness of the measurements to each other
It's been a while since I've done this stuff... I'm pretty confident 3. is decibels. 2 could be perception (because perception is the pitch that a human hear designates to the frequency it receives). I'm unsure about the first one.
Answer:
No, it doesn't.
Explanation:
To convert ppb to mg/m³ we first need to convert to ppm, by just divide the amount by 1,000, so the concentration in the sample is 4.8 ppm.
mg/m³ = (ppm x molar mass)/molar volume
Using the molar mass in gram and the molar volume in liters, multiplying by the parts per million, we will get the concentration in mg/m³.
Molar mass of C = 12 g/mol; molar mass of Cl = 35.5 g/mol
Molar mass of CCl4 = 12 + 4x35.5 = 154 g/mol
Assuming, 25ºC and 1 atm, the molar volume of an ideal gas is 24.45 L, so:
mg/m³ = (4.8 x 154)/24.45
mg/m³ = 30.2
Which is higher than the limit of 12.6 mg/m³
