Answer:
i) 24.305 u
iv) The number of protons determines an element's atomic number and is used to distinguish one element from another.
Mass = molarity x molar mass( NaNO₃) x volume
mass = 1.50 x 85.00 x 4.50
mass = 573.75 g of NaNO₃
hope this helps!
Missing question: What is the total combined mass of carbon dioxide and water that is produced?
Chemical reaction: gasoline + O₂ → CO₂ + H₂O.
For this question use mass conservation law (mass of products is equal to mass of reagents): m(reactants) = m(products of reaction).
m(gasoline + oxygen) = m(carbon(IV) oxide + water).
m(carbon(IV) oxide + water) = 20 kg + 83 kg = 103 kg.
Answer:
The answer is 6 valance electrons because it is oxygen and oxygen needs two more electrons to be a noble gas
