Answer:
Explanation:
A) Reactant that can produce more of the product
Excess reactant:
In a given reaction, the reactant that is in excess supply is the excess reactant. If the amount of the excess reactant is match, more of the product will be produced.
B) Reactant that can produce a lesser amount of the product
Limiting reactant
The limiting reactant restricts the progress of the reaction. It determines the amount of product that can be formed.
C) Amount of product predicted to be produced by the given reactants
Theoretical yield
For a given amount of reactants, the theoretical yield determines the amount of products that can be produced.
Answer:
The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023). Calculate the number of atoms in 2.45 mol of copper. A silver ring contains 1.1 x 1022 silver atoms.

Answer:
37.1g are produced
Explanation:
The combustion of C₈H₁₈ is:
C₈H₁₈ + 25/2O₂ → 8CO₂ + 9H₂O
<em>Where 1 mole of C₈H₁₈ produce 8 moles of CO₂</em>
<em />
To find the mass of CO₂ that is produced we need to convert the mass of C₈H₁₈ with molar mass. Then, with the chemical equation, we can find the moles of CO₂ and its mass, as follows:
<em>Moles C₈H₁₈ -Molar mass: 114.2g/mol-</em>
12g C₈H₁₈ * (1mol / 114.2g) = 0.105 moles of C₈H₁₈
<em>Moles CO₂:</em>
As 1 mole of C₈H₁₈ produce 8 moles of CO₂, 0.105 moles of C₈H₁₈ produce:
0.105 moles of C₈H₁₈ * (8moles CO₂ / 1mole C₈H₁₈) = 0.84 moles of CO₂
<em>Mass CO₂ -Molar mass: 44.01g/mol-:</em>
0.84 moles of CO₂ * (44.01g / mol) = 37.0g of CO₂ ≈
<h3>37.1g are produced</h3>
<h3>Answer:</h3>
Cyclopentane (C5H10)
<h3>Explanation:</h3>
The molar mass of CH2 is about 14.3, Since empirical is a ratio just divide the given molar mass by the molar mass of the empirical. 70.15/14.3=5 So now multiple everything by 5 in the empirical equation.
So, a compound that has an empirical formula of CH2 and a molar mass of 70.15 will have molecular formula of" C5H10".
