Answer:

<h2>Cells are important for living organisms because cells are the basic building blocks from which all organisms are created.</h2>

Explanation:

While some organisms are comprised of a single cell, others are multicellular entities with different cell types. Humans, for example, have many different types of cells, including nerve cells, skin cells and fat cells.

A mole of one element contains _______ number of atoms as a mole of another element.
Vera_Pavlovna [14]

A mole of one element contains Same number of atoms as a mole of another element.

The atomic mass of an element, that is found on the periodic table, may be used to determine the amount of moles in a system. Typically, this mass represents the average of the element's abundant forms found on earth. The mass of an element is given as the average of all of its earthly isotopes. The molar mass of a material is the weight of a mole of that substance. In chemistry, the molar mass is frequently used in converting grams of a chemical to moles. The periodic table lists an element's molar mass, which is its atomic weight in grams per mole (g/mol).

The average mass of an element's atoms expressed in atomic mass units is known as its atomic mass (amu, also known as daltons, D). The weight of the each isotope is combined by its abundance to get the atomic mass, which is a weighted average of all the isotopes of that element.

1. mol ratio of Al(NO₃)₃ : Na₂CO₃ = 2 : 3

2. Na₂CO₃ as a limiting reactant

<h3>Further explanation</h3>

Given

Reaction

2 Al(NO₃)₃ + 3 Na₂CO₃ → Al₂(CO₃)₃ + 6 NaNO₃

Required

mol ratio

Limiting reactant

Solution

The reaction coefficient in the chemical equation shows the mole ratio of the components of the compound involved in the reaction (reactants and products)

1. From the equation mol ratio of Al(NO₃)₃ : Na₂CO₃ = 2 : 3

2. mol : coefficient of Al(NO₃)₃ : Na₂CO₃ = 2 mole/2 : 2 mole/3 = 1 : 0.67

Na₂CO₃ as a limiting reactant (smaller)

How many moles of Al are needed to react exactly with 10.00 moles of Fe2O3 according to the following
4vir4ik [10]

Answer:

Answer is B) 20.0 moles

Explanation:

From the equation,

1 mole of Fe2O3 = 2 moles of Al

therefore 10.0 moles of Fe2O3 = 10×2

= 20.0 moles.
