How many moles of calcium oxide are produced when 36.5 grams of calcium reacts completely with oxygen gas?
1 mole of calcium oxide is produced for every mole of calcium reacting with oxygen. To find the number of moles of calcium reacting, divide the mass of calcium by its molar mass. Then, use the mole ratio from the balanced chemical equation to find the moles of calcium oxide produced.
Is Calcuim oxide corrosive?
Yes, calcium oxide is corrosive. It reacts with water to produce calcium hydroxide, which is strongly alkaline and can cause burns on contact with skin. It is important to handle calcium oxide with care and use appropriate protective equipment.
What is the chemical formula of the compound made by combining calcium and oxygen Use Lewis structures to help you decide your answer.?
The calcium oxide is CaO.
How can sulfur dioxide be removed using calcium oxide?
Sulfur dioxide can be removed by scrubbing the gas with a solution of calcium oxide. The calcium oxide reacts with sulfur dioxide to form calcium sulfite, which can then be further oxidized to calcium sulfate. This process helps to reduce the concentration of sulfur dioxide in the gas stream.
How many grams of calcium oxide are needed to produce 36.0 g of hg?
To calculate the amount of calcium oxide needed to produce 36.0 g of mercury (Hg), we need to first determine the molar ratio between calcium oxide and mercury. The molar ratio can be determined from the balanced chemical equation of the reaction. Once the molar ratio is known, we can use it to find the amount of calcium oxide needed to produce 36.0 g of mercury.
If calcium oxide can be present by heating calcium metal in oxygen How much calcium would be needed to make 15.0 g of calcium oxide?
To find out how much calcium is needed to make 15.0 g of calcium oxide (CaO), you have to consider the molar ratio of calcium to calcium oxide. The molar mass of CaO is 56.077 g/mol, and the molar mass of Ca is 40.078 g/mol. This means that for every 1 mol of CaO, you need 1 mol of Ca. Calculate the number of moles of CaO in 15.0 g, then use the molar ratio to find the moles of Ca needed. Finally, convert the moles of Ca to grams to find out how much calcium is needed to make 15.0 g of CaO.
Why use calcium oxide with nail?
Calcium oxide, also known as quicklime, can be used to help remove rust from nails by reacting with water to produce calcium hydroxide. This chemical reaction can help loosen the rust from the surface of the nail, making it easier to clean and restore the nail to its original condition.
Why do farmers spray powdered calcium carbonate over their field?
Farmers use calcium carbonate to lowervthe pH.
Why do farmers sometimes use calcium oxide in the fields?
Farmers use calcium oxide, also known as quicklime, to help balance soil pH levels and improve soil structure. It can also help control harmful pests and diseases in the soil, as well as enhance the availability of certain nutrients for plant growth.
Where does the phrase 'to be in the limelight' come from?
Calcium Oxide, or lime, is a mineral in the periodic table that, like magnesium, gives off a bright white light when burnt. Sometimes, on stages, film/production makers used to use Calcium Oxide to light up the stage, which is where the phrase came from.
Reactants would you use to make calcium chloride plus water?
To make calcium chloride and water, you would react calcium oxide or calcium hydroxide with hydrochloric acid. The reaction would be CaO + 2HCl → CaCl2 + H2O or Ca(OH)2 + 2HCl → CaCl2 + 2H2O.
