Explanation:
To write the Potassium electron configuration, we first need to know the number of electrons for the K atom (there are 19 electrons). When we write the configuration we'll put all 29 electrons in orbitals around the nucleus of the Potassium atom.
Answer:
Mass = 90.1 g
Explanation:
Given data:
Number of moles of carbon dioxide = 3 moles
Mass of glucose produced = ?
Solution:
Chemical equation:
6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂
Now we will compare the moles of CO₂ and C₆H₁₂O₆.
CO₂ : C₆H₁₂O₆
6 : 1
3 : 0.5
Mass of glucose:
Mass = number of moles × molar mass
Mass = 0.5 mol × 180.2 g/mol
Mass = 90.1 g
Answer:
Mark has a speed of 6 MPS (Miles Per Hour)
Explanation:
It took mark 2 hours to ride his bike to his grandma's house, which was 12 miles away. I divided 2 by 12 and got 6. Remember this: mph = miles away ÷ time.
