Answer:
A. Distance from the moon.
Answer:
= 3.78 g H₂O
Explanation:
2C₂H₆ + 3O₂ => 4CO₂ + 6H₂O
2.1g C₂H₆ = 2.1g/30.0 g/mol = 0.07 mole ethane
3.68g O₂ = 3.68g/32 g/mol = 0.115 mole oxygen
Limiting Reactant:
A quick way to determine limiting reactant is to divide moles of reactant by its respective coefficient in the balanced molecular equation. The smaller value is the limiting reactant.
moles ethane = 0.07 mole / 2 (the coefficient in balanced equation) = 0.035
moles oxygen = 0.115 mole / 3 (the coefficient in balanced equation) = 0.038
Since the smaller value is associated with ethane, then ethane is the limiting reactant and the problem is worked from the 0.07 moles of ethane in an excess of O₂.
From the equation stoichiometry ...
2 moles C₂H₆ in an excess of O₂ => 6 moles H₂O
then 0.07 mole C₂H₆ in an excess of O₂ => 6/2(0.07 moles H₂O = 0.21 mole
Converting to grams of water produced
= 0.21 mole H₂O X 18 g/mol = 3.78 g H₂O
Answer:
Its conduction
Explanation:
Its when heat is transferred from a object to something else.

The lack of an outlet will affect the composition of these lakes by causing an accumulation of organic and inorganic nutrients due to decomposition of living materials.
<h3>What is a lake?</h3>
Lake is a small stream of running water or a channel for water.
Lakes are usually a standing body of water or slow moving. This means that some lakes, including the Great Salt Lake and the Dead Sea, have no outlet.
The lack of an outlet will affect the composition of these lakes by causing an accumulation of organic and inorganic nutrients due to decomposition of living materials.
