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

Hydrogen has three isotopes 1H, 2H, and 3H. What is the difference between these three isotopes?
Leona [35]
The main difference between the 3 isotopes of hydrogen are the number of neutrons in the nucleus. Hydrogen has no neutrons, Deuterium has one neutron, and tritium has two neutrons. All three have one proton and one electron.

In this item, we are simply to find the ions that may bond and are able to form a formula unit. We are also instructed to give out their name. There are numerous possible combinations of ions to form a compound. Some answers are given in the list below.

1.  Na⁺     ,    Cl⁻    , NaCl   ---> sodium chloride (this is most commonly known as table salt)

2. C⁴⁺       , O²⁻     , CO₂  ---> carbon dioxide

3. Al³+     , Cl⁻       , AlCl₃   ----> aluminum chloride

4. Ca²⁺     , Cl⁻     , CaCl₂    ---> calcium chloride

5. Li⁺        , Br⁻      , LiBr       ---> lithium bromide

6. Mg³⁺     , O²⁻      , Mg₂O₃   ----> magnesium oxide

7. K⁺        , I⁻          , KI   ---> potassium iodide

8. H⁺        , Cl⁻        , HCl  --> hydrogen chloride

9. H⁺        , Br⁻         , HBr ----> hydrogen bromide

10. Na⁺    , Br⁻         , NaBr   ---> sodium bromide

When 6.85×10⁵ cal is converted to kilojoules, the result obtained is 2866.04 KJ

<h3>Data obtained from the question </h3>
  • Energy (cal) = 6.85×10⁵ cal
  • Energy (KJ) =?

<h3>Conversion scale </h3>

1 cal = 0.004184 KJ

<h3>How to convert 6.85×10⁵ cal to kilojoules</h3>

1 cal = 0.004184 KJ

Therefore,

6.85×10⁵ cal = 6.85×10⁵ × 0.004184

6.85×10⁵ cal = 2866.04 KJ

Thus, 6.85×10⁵ cal is equivalent to 2866.04 KJ
