3) Volume is the amount of space an object takes up.
6) Gallons and inches are customary units of measurement, while (grams, kilograms, meters, centimeter, milliliter) are metric units of measurements.
8) When using a thermometer, the liquid goes up in the tube when the temperature increases. The liquid goes down in the tube when the temperature decreases.
9) The instrument used to find the volume of a liquid is a graduated cylinder.
15) Units of measurement that can be used to measure mass are called grams and kilograms.
17) The temperature is measured in Fahrenheit in the customer system and Celsius in the metric system.
I think it's either B or D
Explanation:
it really depends on how differently shaped the beakers are sorry if this doesn't help very much
Explanation:
When ethyne undergoes a hydrogenation reaction with Ni catalyst and excess hydrogen,
C2H2 + 2H2 => C2H6.
Ethyne reacts with hydrogen gas to form ethane.
Answer:
Answer is explained below in the explanation section
Explanation:
Smaller signal is observed at a mass 1 amu because small percentage of the compound will have carbon isotope of 13C instead of 12C.
As we know, mass spectrometry is done as a small compound is first vaporized and then bombarded to ionize it. And then, those ions are accelerated forward and then at some point ions are separated and deflected by the application of magnetic field.
And finally hits the detector to give us a spectrum to read. So, in this whole procedure, there can be a small percentage of carbon isotope of 13C instead of 12C in that compound and showed in the spectrum as a smaller signal at a mass 1 amu.
