What is the number of ions in a 6.58 mole sample of NaCl?
The number of ions in a 6,58 mole sample of NaCl is 79,25137367812.10e23.
How does the experimental mole ratio compare with the theoretical mole ratio?
The experimental mole ratio is obtained from actual experimental data, while the theoretical mole ratio is calculated based on the balanced chemical equation. Comparing the two can reveal discrepancies and provide insight into the accuracy of the experimental results or any potential sources of error in the experiment.
What is the difference between the mass of a mole of oxygen and a mole of O2 molecules?
A mole of oxygen atoms has a mass of approximately 16 grams. A mole of O2 has a mass of approximately 32 grams. A mole is 6.02 x 1023 particles and as such a mole of oxygen atoms has only half the mass of a mole of oxygen molecules.
How many atoms of O2 are in a 1.76sample of CO2?
1.76 grams CO2 (1 mole CO2/44.01 grams)(2 mole O/1 mole CO2)(6.022 X 10^23/1 mole O2) = 4.82 X 10^22 atoms of oxygen gas
What is the ratio of hydrogen atoms to oxygen in glucose and fructose?
Glucose is C6H12O6 and thus the mole ratio is 6 moles of carbon to 6 moles of Hydrogen Molecules (12 moles of Hydrogen atoms) and 3 moles of oxygen molecules (6 moles of oxygen atoms)
What is the mole ratio of oxygen to pentane?
The mole ratio of oxygen to pentane in the balanced chemical equation for the combustion of pentane is 13:1. This means that 13 moles of oxygen are required to completely react with 1 mole of pentane.
The sample is not completely thermally decomposed in the procedure will the mole ratio of CaO To CO2 be too high or too low. explain?
If the sample is not completely thermally decomposed, the mole ratio of CaO to CO2 will be too high. This is because there will be unreacted CaCO3 remaining in the sample, leading to an overestimation of the amount of CaO present and, consequently, an inflated mole ratio.
How if the magnesuim is not polished would the reported mole ratio of oxygen to magnesium be too high too lowor unaffected?
If the magnesium is not polished, there may be impurities or oxides on the surface that could affect the reported mole ratio of oxygen to magnesium. This could result in a higher reported mole ratio due to the presence of excess oxygen-containing compounds on the surface, leading to an inaccurate measurement of the actual ratio of oxygen to magnesium.
What is the mole ratio of aluminum to oxygen?
The mole ratio of aluminum to oxygen in aluminum oxide (Al2O3) is 4:3, which means for every 4 moles of aluminum, there are 3 moles of oxygen.
If the burning of the magnesium ribbon was out of control would it affect the mole ratio of oxygen to magnesium?
No. According to the law of definite proportions, the mole ratio will always be the same.
What is the molar ratio of hydrogen to oxygen?
The molar ratio of hydrogen to oxygen in water (H2O) is 2:1. This means that for every 2 moles of hydrogen, there is 1 mole of oxygen.
What is the mole ratio of air to methane gas in the cumbustion of methane?
The balanced chemical equation for the combustion of methane is CH4 + 2O2 -> CO2 + 2H2O. This means that the mole ratio of air to methane gas is 2:1, as two moles of oxygen from the air are required to react with one mole of methane gas.
Will 27 grams of aluminium react completely with 24 grams of oxygen?
Yes.Explanationary:27 g Al = 1.0 mole Al24 g = 1.5 mole O2 so this ratio (in mole) is 1:1.52Al + 3O2 --> Al2O3 so the balanced mole ratio is 2:3 or 1:1.5
Use the mole ratio to determine the number of moles of carbon dioxide produced when 0.136 mole of 1-heptanol reacts with excess oxygen in a combustion reaction?
0.95 - 0.954
Methanol stoichiometric ratio?
The stoichiometric ratio for methanol is 1:1. This means that one mole of methanol reacts with one mole of an oxidizer, such as oxygen, in a complete combustion reaction. This ratio is essential to calculate the amount of reactants needed to ensure complete conversion of methanol to products.
Is a 16.00-g sample of oxygen atoms contains the same number of particles as a 4.003-g sample of He atoms?
Yes. 16.00g of oxygen is its molar mass, which is the mass of one mole of oxygen. 4.003g is the molar mass of helium, which is also the mass of one mole of helium. One mole of anything is 6.022 x 1023. One mole of oxygen atoms is 6.022 x 1023 atoms of oxygen and one mole of helium atoms is 6.022 x 1023 atoms of helium.
What is the empirical formula of 0.039 mole of iron atoms combined with 0.052 mole of oxygen atoms?
Divide the larger mole number by the smaller, which is 1 0.052 mole O/0.039 mole Fe = 1.3333 Using judgment here one calls this number 1 so FeO empirical formula and ferrous oxide
