Answer: Lithium
Explanation: The balanced chemical equation is:
It can be seen, 4 moles of lithium combines with 1 mole of oxygen gas to produce 2 moles of lithium oxide.
Thus 8.4 moles of lithium combines with=of oxygen gas to produce 4.2 moles of lithium oxide.
As, Lithium limits the formation of product, it is the limiting reagent and Oxygen gas is present in excess, it is called the excess reagent. (4.6-2.1)=2.5 moles of oxygen gas are present in excess.
Answer:
Land and sea breeze
Explanation:
This uneven warming of the land during the day results in the phenomenon called land and sea breeze.
- During the day, the land heats up faster than the nearby ocean.
- Ocean is made up of water with a high specific heat capacity.
- This derives pressurized air near the surface of the land to the ocean.
- At night, the ocean does not easily lose heat after the land has lost its own.
- Pressurized air moves from the ocean to the land.
- This causes the warming of the land during the night.
Answer:
either deposition or physical weathering
Answer:
Answer is: Keq = [CO₂].
Explanation:
Balanced chemical reaction: CaCO3(s) ⇄ CaO(s) + CO₂(g).
The equilibrium constant (Keq) is a ratio of the concentration of the products to the concentration of the reactants.
Pure liquids (shown in chemical reactions by appending (l) to the chemical formula) and solids (shown in chemical equations by appending (s) to the chemical formula) not go in to he equilibrium constant expression, only gas state (shown in chemical reactions by appending (g) to the chemical formula) reactants and products go in to the equilibrium constant expression
