Answer:Stoichiometry calculations are about calculating the amounts of substances that react and form in a

chemical reaction. For example, based on the balanced chemical equation, we can calculate the

amount of a product substance that will form if we begin with a specific amount of one or more

reactants. Or, you may have a target amount of product to prepare. How much starting compounds

are needed to prepare this amount? These are practical calculations that are done frequently by

chemists.

The Method

For practically all stoichiometry problems, we want to use the. . . .

Fabulous Four Steps

Step 1: Write the balanced chemical equation for the reaction.

Step 2: Calculate the moles of "given" substance. If more than one reactant amount is given,

calculate the moles of each to determine which is the limiting reactant.

Step 3: Calculate the moles of "desired" substance from your answer in Step 2 using the

coefficients from the balanced chemical equation. If more than one reactant was given originally, you

can calculate the moles of product twice, based on the moles of each reactant. The reactant that

gives the smaller moles of product is the limiting reactant. Keep this answer for Step 4.

Step 4: Convert your answer in Step 3 to the units the problem asks for. Usually this is grams,

but it could be volume (for gases or liquid solutions) or concentration (such as molarity, for solutions).

Again in brief:

1. Balanced reaction

2. Moles of "given" substance(s)

3. Moles of "desired" substance such as a product

4. Convert Step 3 answer to the units asked fo

What are three units you can measure moler mass in
liraira [26]

By looking at a periodic table, we can conclude that the molar mass of lithium is 6.94g, the molar mass of zinc is 65.38g, and the molar mass of gold is 196.97g. Each of these quantities contains 6.02×1023 atoms of that particular element. The units for molar mass are grams per mole, or g/mol.

So The answers are Lithium, Gold, Zinc

How many moles of nitrogen trifluoride (NF3) can be produced from 9.65 mole of Fluorine gas (F2)
user100 [1]

Answer:

6.43 moles of NF₃.

Explanation:

The balanced equation for the reaction is given below:

N₂ + 3F₂ —> 2NF₃

From the balanced equation above,

3 moles of F₂ reacted to produce 2 moles of NF₃.

Finally, we shall determine the number of mole of nitrogen trifluoride (NF₃) produced by the reaction of 9.65 moles of Fluorine gas (F₂). This can be obtained as follow:

From the balanced equation above,

3 moles of F₂ reacted to produce 2 moles of NF₃.

Therefore, 9.65 moles of F₂ will react to to produce = (9.65 × 2)/3 = 6.43 moles of NF₃.

Thus, 6.43 moles of NF₃ were obtained from the reaction.

Why neon is special from other chemical elements​
kupik [55]
Noble gases react very unwillingly, because the outermost shell of electrons orbiting the nucleus is full, giving these gases no incentive to swap electrons with other elements. As a result, there are very few compounds made with noble gases. Like its noble gas comrades, neon is odorless and colorless.
