Answer:
160 g
Explanation:
The chemical equation is:
C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + 6H₂O(g)
According to the equation, 1 mol of glucose (C₆H₁₂O₆) reacts with 6 moles of O₂. We calculate the masses of the reactants from the molar masses of the chemical elements:
1 mol C₆H₁₂O₆ = (6 x 12 g/mol)+ (12 x 1 g/mol) + (6 x 16 g/mol) = 180 g
6 mol O₂ = 6 x (2 x 16 g/mol) = 6 x 32 g/mol = 192 g
So, 180 g of C₆H₁₂O₆ reacts with 192 g of O₂. The stoichiometric ratio is 192 g O₂/180 g C₆H₁₂O₆. To calculate the grams of O₂ needed to react with 150 g of C₆H₁₂O₆ we can simply multiply the stoichiometric ratio by the grams of C₆H₁₂O₆:
150 g C₆H₁₂O₆ x 192 g O₂/180 g C₆H₁₂O₆ = 160 g O₂
Therefore, 160 grams of O₂ are needed to fully react with 150 g of glucose.
Answer:
Ne
Explanation:
Neon is the 10th element in the periodic table, and it has all of its orbitals filled up with electrons, the electronic configuration of the element that contains 168 electrons will be an electronic configuration that ends up with all of the orbitals filled up, so it would be most similar to the Neon which is a noble gas, meaning that 168th element will also be a noble gas.
