Answer:
B. how fast the particles are moving
Explanation:
Temperature measures the average kinetic energy of system as result of the thermal - heat energy present in the reaction or a body.
Often times, temperature is the degree of hotness or coldness of a body and this translates to an increase or decrease in the molecular speed.
- Number of particles in a body is the mass of the body.
- How tightly packed the particles are corresponds to the density of the body.
Answer: both are equal
They weighed the same because they both a pound
Convert the 48.7 grams into moles and then use the balanced equation to convert to moles of hydrogen gas. Then divide by avogadro's number<span />
Answer:
You are looking for expected peaks in absorption spectra founded on structure of desired product, respectively on bound in desired compound. Every bond absorb specific energy from radiation which wavelength match to IR spectrum of light. Result of energy absorption is vibration of bond and bonded atoms (if they are not too heavy).That absorbed energy is seen as a peak in absorption spectra. These peaks are specific for each bound so you need to find peaks that mach to bounds in your desired compound and in that matter you can identify your compound.
In nuclear magnetic resonance you are looking for peaks specific for atoms in your desired compound (H or C atoms). When external magnetic field is applied, atom goes in higher energy state. When atoms goes "relaxing", it releasing energy that mach energy gap from relaxed end excited state. That energy is detected on nuclear magnetic resonance spectra and it depends on neighbor atom so you can determine the position of atoms and identify structure of desired compound.
For better results it is the best to combine these two methods.
