What mass of potasium oxide is formed when 7.8g of potasium is burned in oxygen?
When potassium is burned in oxygen, it forms potassium oxide according to the balanced chemical equation: 4K + O2 → 2K2O. The molar mass of K is 39.10 g/mol and that of K2O is 94.20 g/mol. Using stoichiometry, we find that 7.8g of potassium will form 7.8g * (1 mol K / 39.10 g K) * (1 mol K2O / 4 mol K) * (94.20 g K2O / 1 mol K2O) = 4.57g K2O.
What is the chemical formula of ionic compound potassium oxide?
Three potassium oxides are known: K2O, KO2, K2O2.
What does potassium and oxygen form what ionic compound?
The combination of potassium (K) and oxygen (O2) produces K2O (potassium oxide). The balanced equation is 2K + O2 ==> K2O. The answer provided previously is incorrect. The compound KO does not exist.
How many moles of potassium oxide (K2O) will be formed when 1.52 moles of potassium reacts with oxygen according to the following reaction 4 K O2 2 K2O?
According to the reaction (4 \text{K} + \text{O}_2 \rightarrow 2 \text{K}_2\text{O}), 4 moles of potassium produce 2 moles of potassium oxide (K2O). Thus, the mole ratio of potassium to K2O is 4:2, or 2:1. If 1.52 moles of potassium are used, the number of moles of K2O formed can be calculated as (1.52 , \text{moles K} \times \frac{2 , \text{moles K2O}}{4 , \text{moles K}} = 0.76 , \text{moles K2O}). Therefore, 0.76 moles of potassium oxide will be formed.
What is the symbol for potassium plus oxygen?
An equation refers to a reaction, not an individual compound. The formula of potassium oxide is K2O. If you mean the equation for its formation from the elements, it is 4K + O2 --> 2K2O.
Is K2O a ionic bond or a covalent bond?
K2O forms an ionic bond. In the compound, potassium (K) donates an electron to oxygen (O) to form K+ and O2- ions, resulting in the attraction between the positively and negatively charged ions that makes up the ionic bond.
What are the word equation for the reaction that causes potassium to tarnish?
The word equation for the reaction that causes potassium to tarnish is: potassium (K) + oxygen (O2) → potassium oxide (K2O).
