Why was cao cao able to defeat yuan shao at guan du?
Cao Cao was able to defeat Yuan Shao at the Battle of Guandu mainly due to his strategic prowess, military tactics, and effective use of spies. Cao Cao also had a well-disciplined and experienced army, which allowed him to outmaneuver and outsmart Yuan Shao's larger but less organized forces.
Calculate the mass of lime CaO that can be prepared by heating 200kg of limestone that is 95 percent pure CaCo?
To calculate the mass of CaO that can be prepared from 200kg of limestone that is 95% CaCO3, first calculate the mass of CaCO3 in the limestone: 200kg * 0.95 = 190kg. Next, use the molar mass of CaCO3 (100.09 g/mol) and CaO (56.08 g/mol) to determine the mass of CaO formed: (190kg * 1000g/kg * 56.08g/mol) / 100.09g/mol = 107,004 g or 107.004 kg of CaO.
How many formula units are contained in 1.34g CaO?
To calculate the number of formula units in 1.34g of CaO, we first need to find the molar mass of CaO. CaO has a molar mass of 56.08 g/mol. Next, we convert the given mass to moles using the formula: moles = mass / molar mass. Finally, we use Avogadro's number (6.022 x 10^23) to convert moles to formula units.
What is the correct compound name for CaO?
The correct compound name for CaO is calcium oxide.
How do you convert between the molar percentage of a compound e.g. CaO and the atomic percentage of the elements e.g. Ca and O?
To convert from the molar percentage of a compound to the atomic percentage of its elements, you can use the molar mass of each element to calculate the number of moles of each element in one mole of the compound. Then, you can use these values to determine the atomic percentage of each element. For example, in CaO, one mole of CaO contains 1 mole of Ca and 1 mole of O. So, the atomic percentage of Ca would be (molar percentage of CaO) * (molar mass of Ca) / (molar mass of CaO), and similarly for O.
