The effect of vapor condensation in the neck a beryl type pipet have on the reported molar mass?
Vapor condensation in the neck of a beryl type pipet leads to inaccurate measurements due to the presence of water droplets. These droplets can alter the volume of the gas being collected, resulting in a higher reported molar mass than the actual molar mass of the gas. It is important to account for and correct this error in order to obtain accurate results.
If 100 g of CuS and 56 g of O2 are available which is the limiting reactant?
To determine the limiting reactant, first calculate the moles of each reactant by dividing the given mass by their respective molar masses. Then, determine the mole ratio between CuS and O2 in the balanced chemical equation. The reactant that produces fewer moles of product based on this ratio is the limiting reactant.
Why the specific molar conductivity of 0.01 M KOH is much higher than the specific conducivity of 0.01M KCl?
This is true because KOH has a high concentration of hydrogen ions (H+) and this increases the conductivity of KOH to be significantly higher than that of KCl. KCl has a very highly electronegative ion Cl- Hydrogen bonding occurs at sites of electronegativity which will interfere conductivity at lower concentrations of these Ions
What is the relationship between molar mass and evaporation rates?
They are inversely related. This means that as molar mass increases, the rate of evaporation decreases. This is because as molar mass increases, the intermolecular bonds also get stronger, and it is more difficult to break those bonds and for liquid molecules to jump into a gaseous state.
The molar mass of C3H8O2 is?
to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu) to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu)
Which ions is the limiting reagent and which is the reagent in excess when barium sulphate is made?
When barium sulfate is made, the limiting reagent is the one that is completely consumed in the reaction and determines the amount of product formed. In this case, if barium ions (Ba2+) and sulfate ions (SO42−) are the reactants, the limiting reagent would be the one that is present in lower molar quantity. The one in excess would be the one that is present in higher molar quantity. Without the quantities of each ion provided, it is difficult to determine which is the limiting reagent and which is in excess.
What is the limiting reagent when g of P and g of I react?
To determine the limiting reagent, you need to find the molar amounts of each reactant. Compare the molar amounts of P and I to the balanced chemical equation to see which one is present in the lower stoichiometric amount. The reactant that gives the smaller amount of product is the limiting reagent.
What is the molar conductivity of kcl in infinit dilution?
Infinite dilution molar conductivity is the limiting value of the molar conductivity as the concentration tends to zero. The molar conductivity of KCl at infinite dilution is approximately 149.9 S cm² mol⁻¹ at 25°C.
Which molecule, based on its molar mass, would have a higher rate of effusion?
The molecule with a lower molar mass would have a higher rate of effusion.
What is the relationship between molar mass and density in a substance?
The relationship between molar mass and density in a substance is that as the molar mass of a substance increases, its density also tends to increase. This is because a higher molar mass means there are more particles packed into a given volume, leading to a higher density.
What is the relationship between the molar mass and density of a substance?
The relationship between the molar mass and density of a substance is that the molar mass affects the density of a substance. Generally, substances with higher molar masses tend to have higher densities. This is because the molar mass represents the mass of one mole of a substance, and denser substances have more mass packed into a given volume.
If 638.44 g CuSO4 reacts with 240.0 g NaOH which is the limiting reagent?
Sodium hydroxide is the limiting reagent.
What is the relationship between the molar mass of a gas and its density?
The relationship between the molar mass of a gas and its density is that as the molar mass of a gas increases, its density also increases. This means that gases with higher molar masses will be denser than gases with lower molar masses.
What mass of HgBr2 can be produced from the reaction of 10.09 g Hg and 8.02 g Br2?
First, balance the chemical equation: Hg + Br2 → HgBr2. Calculate the molar amount of each reactant using their respective molar masses. Identify the limiting reactant (the one that produces the least amount of product). Calculate the theoretical yield of HgBr2 based on the limiting reactant.
what are the gases diffuse at lowest rate?
gases with the higher molar mass
Which reagent is limiting cyclopentadiene or maleic anhydride?
To determine the limiting reagent, calculate the moles of each reactant using their respective masses and molar masses. Compare the moles of each reactant to the stoichiometry of the reaction. The reagent that produces the least amount of product based on stoichiometry is the limiting reagent.
What is the relationship between temperature and molar entropy in a chemical system?
The relationship between temperature and molar entropy in a chemical system is that as temperature increases, the molar entropy also increases. This is because higher temperatures lead to greater molecular motion and disorder, resulting in higher entropy.
