Answer:
B. Excited state
Explanation:
Energy levels higher than the ground state are called the excited states. This concept is based on the premise that electrons can move round the nucleus in certain permissibe orbits or energy levels.
The ground state is the lowest energy state available to the electron. This is usually the most stable state.
The excited state is any level higher than the ground state. An electron in an energy level has a definite amount of energy associated with it at that level.
Brass is an alloy, or a combination of two (or more) metals.
Answer:
3.66 moles of Zinc Oxide are consumed
Explanation:
Based on the reaction:
C + 2ZnO → 2Zn + CO₂
<em>Where 1 mole of Carbon reacts with 2 moles of Zin Oxide to produce 2 moles of Zinc and 1 mole of Carbon Dioxide.</em>
<em />
To solve this question, we must convert the moles of carbon added to the moles of Zinc Oxide that react using the chemical equation (1mol C = 2mol ZnO):
1.83 moles C * (2mol ZnO / 1mol C) =
<h3>3.66 moles of Zinc Oxide are consumed</h3>
