For each of the four single-displacement reactions, describe what happened in rachel well. if a chemical reaction occured, write a balanced equation for it. then using the a, b symbols, write a general equation for a single-displacement reaction.
hi! glucose and oxygen are required for cellular respiration. as the law of conversation states, in a biochemical reaction, mass is conserved. for every glucose molecule, 6 oxygen molecules are used up and the end products, other than the energy dissipated by the reaction, are 6 water molecules and 6 carbon dioxide molecules. brainliest?
answer : the rms speed of the molecules in a sample of gas at 300 k will be four times larger than the rms speed of molecules at the same temperature, and the ratio constant with increasing temperature.
formula used for root mean square speed :
= rms speed of the molecule
r = gas constant
t = temperature
m = molar mass of the gas
at constant temperature, the formula becomes,
and the formula for two gases will be,
molar mass of = 32 g/mole
molar mass of = 2 g/mole
now put all the given values in the above formula, we get
therefore, the rms speed of the molecules in a sample of gas at 300 k will be four times larger than the rms speed of molecules at the same temperature.
and the ratio constant with increasing temperature because rms speed depends only on the molar mass of the gases at same temperature.
