The amount of the product in grams, formed from the limiting reactant is the theoretical yield

<u>Explanation:</u>

In a chemical reaction when the limiting agent is completely reacted and the product obtained is termed as Theoretical yield. The amount of product yield that is attained through a complete reaction of the limiting agent is the theoretical yield. Grams or moles is used for expressing theoretical yield.

This is calculated form the limiting agent in a complete chemical reaction which is balanced. If a chemical reaction is unbalanced, it should be first balanced to find the theoretical yield. Then, the limiting agent must be found. When the limiting agent is small in quantity, the reaction cannot be completed once the limiting agent is fully used and exhausted.

saw5 [17]

B is true because liquids are still more compact than gases, although they are loose, they aren't completely free. They also don't have a definite volume, making them assume the shape of their container. As for compression, liquids are harder to compress compared to gases.

please hurry! If 3.87g of powdered aluminum oxide is placed in a container containing 5.67g of water, what is the limiting react

VikaD [51]

Answer:

Explanation:

Given parameters:

Mass of aluminium oxide = 3.87g

Mass of water = 5.67g

Unknown:

Limiting reactant = ?

Solution:

The limiting reactant is the reactant in short supply in a chemical reaction. We need to first write the chemical equation and convert the masses given to the number of moles.

Using the number of moles, we can ascertain the limiting reactants;

Al₂O₃ + 3H₂O → 2Al(OH)₃

Number of moles;

Number of moles = $\frac{mass}{molar mass}$

molar mass of Al₂O₃ = (2x27) + 3(16) = 102g/mole

number of moles = $\frac{3.87}{102}$ = 0.04mole

molar mass of H₂O = 2(1) + 16 = 18g/mole

number of moles = $\frac{5.67}{18}$ = 0.32mole

From the reaction equation;

1 mole of Al₂O₃ reacted with 3 moles of H₂O

0.04 mole of Al₂O₃ will react with 3 x 0.04 mole = 0.12 mole of H₂O

But we were given 0.32 mole of H₂O and this is in excess of amount required.

This shows that Al₂O₃ is the limiting reactant

How does the location of mesosaurus fossils support the theory of continental drifts?<br>

Ratling [72]

Answer:

For this reason, the existence of Mesosaurus helps support the theory of continental drift; that is, the now-well-attested fact that South America and Africa were joined together into the giant continent Gondwana 300 million years ago before the continental plates supporting them broke apart and drifted.

Infer if the mineral Talc would be a good choice when building a statue outside?

ruslelena [56]

Talc is not a good choice when building a statue because the mineral Talc is one of the weakest minerals on the Mohs Scale with a hardness of 1 since it could be scratched by a fingernail, which means that when people build a statue with Talc, it could be easily broken down.
