Ammonium perchlorate reaction is as follows:

2NH4ClO4 ..........> N2 + Cl2 + 2O2 + 4H2O

From the periodic table:

molecular weight of nitrogen = 14 grams

the molecular weight of oxygen = 16 grams

the molecular weight of hydrogen = 1 gram

molecular weight of chlorine = 35.5 grams

From the data above, it was found that:

the molar mass of ammonium perchlorate = 117.5 grams

To produce 28 grams of nitrogen, it is required:

2 x 117.5 = 235 grams.

235 grams of ammonium perchlorate is needed.

To determine the amount of hydrogen produced from 3.1 grams of ammonum percolate, the calculation is as follows:

nitrogen mass = (3.1 x 28) / 235 = 0.369 grams.

So, what is the mass of nitrogen gas produced by the reaction of 3.1 g of ammonium perchlorate is 0.369 grams.

<h2>Further Explanation </h2>

Chemical Compounds are pure chemicals that are composed of two or more elements that can be broken down again by forming elements by chemical reactions. Chemical compounds can be distinguished by chemical formulas by looking at the number of constituent atoms. Chemical compounds can be found in various forms such as in solids, liquids to gases.

Characteristics of Chemical Compounds

There are characteristics of chemical compounds, including:

  • A chemical compound is a form of a single substance
  • It can be broken down into several elements by the number of elements that make up our form through a chemical process or reaction.
  • The composition or number of elements used to form a compound is different. This makes the properties present in chemical compounds differ from those of the constituent elements.
  • Chemical compounds in the form of a combination of chemical elements with a certain ratio.

Properties of Chemical Compounds

Chemical compounds consist of several chemical elements, but the properties of chemical compounds and their constituent elements are different. The following are the properties of chemical compounds, including:

  • Compounds made of several chemical elements through a chemical reaction.
  • The properties that exist in a compound are different from the properties of the elements that make it up. That is because of differences in the composition of the elements used in a chemical compound.
  • Compounds can be broken down into certain elements
  • Cannot be separated physically

Grouping of chemical reactions

The variety of chemical reactions and approaches used in studying them lead to many ways to classify those reactions, which often overlap.

Four basic reactions

  1. Synthesis
  2. Decomposition
  3. Single replacement
  4. Double replacement

The reaction of ammonium perchlorate with itself is as follows:
<span>2NH4ClO4 ..........> N2 + Cl2 + 2O2 + 4H2O 
</span>
From the periodic table:
molecular weight of nitrogen = 14 grams
molecular weight of oxygen = 16 grams
molecular weight of hydrogen = 1 gram
molecular weight of chlorine = 35.5 grams

Therefore:
molar mass of ammonium perchlorate = <span> 117.5 grams

Now, we know that 2 x </span><span> 117.5 = 235 grams of ammonium perchlorate are required to produce 28 grams of nitrogen. We can use cross multiplication to determine the amount of hydrogen produced from 3.1 grams of ammonium perchlorate as follows:
mass of nitrogen = (3.1 x 28) / 235 = 0.369 grams</span>

A sample of an unknown compound with a mass of 0.847 g has the following composition: 50.51 % fluorine and 49.49 % iron. When th
sergejj [24]

Answer: 0,4278g of F and 0,4191g of Fe

Explanation: it's possible to calculate the mass of each element by multiplying the percentage (decimal) of the element by the mass of the compound.

For Fluorine (F)

0,847g * 0,5051 = 0,4278g of F

For iron (Fe)

0,847 * 0,4949 = 0,4191g of Fe

This is determined because even when the compound is decomposed, due to conservative law of mass, the decomposition process do not affect the amount of matter, so the mass of the elements remain even if they are separated from the original molecule.

At the end, the sum of the elements masses should be the total mass of the compound.

From the following enthalpy of reaction data and data in Appendix C, calculate ΔH∘f for CaC2(s): CaC2(s)+2H2O(l)→Ca(OH)2(s)+C2H2
sashaice [31]

Answer:

From the following enthalpy of reaction data and data in Appendix C, calculate ΔH∘f for CaC2(s): CaC2(s)+2H2O(l)→Ca(OH)2(s)+C2H2(g)ΔH∘=−127.2kJ

ΔHf°(C2H2) = 227.4 kJ/mol

ΔHf°(H2O) = -285.8 kJ/mol and

ΔHf°(Ca(OH)2) = -985.2 kJ/mol

(Ans)

ΔHf° of CaC2 = -59.0 kJ/mol

Explanation:

CaC2(s) + 2 H2O(l) → Ca(OH)2(s) + C2H2 (g) = −127.2kJ

ΔHrxn = −127.2kJ

ΔHrxn = ΔHf°(C2H2) + ΔHf°(Ca(OH)2) - ΔHf°(CaC2)- 2ΔHf°(H2O);

ΔHf°(CaC2) = ΔHf°(C2H2) + ΔHf°(Ca(OH)2) - 2ΔHf°(H2O) – ΔHrxn

Where

ΔHf°(C2H2) = 227.4 kJ/mol

ΔHf°(H2O) = -285.8 kJ/mol and

ΔHf°(Ca(OH)2) = -985.2 kJ/mol

ΔHf°(CaC2) =227.4 - 985.2 + 2x285.8 + 127.2 = -59.0 kJ/mol

ΔHf°(CaC2) = -59.0 kJ/mol

A Mole of elephants would weigh how much more than the moon? I got 6.301x10^23 and set the problem up like this: 6.022x10^23 x 2
Margaret [11]

Answer:

The Moon weighs about 7.349*10^22 kg

How much does “an elephant” weigh? Grown-up elephants vary between 1.7 tons (small wood elephant cow) and 6 tons (big African elephant bull). Let us pick 2.720 tons or 2720 kg as an average weigh one, this is valid for Asian elephants.

A mole of elephants weighs 6.022 * 10^23 x 2720 kg = 1.638 * 10^27 kg.

That is 1,638 * 10^27 / 7,349*10^22 = 22289 times more.

The intrinsic solubility of sulfathiazole, an old antimicrobial, is 0.002 mol/l. it is a weak acid and its pka is 7.12. what is
lys-0071 [83]

The formula we will use is:

pH = 0.5 (pKa – log C)

where C is the concentration of sulfathiazole in molarity or mol / L

Since all values are given, we can compute directly for pH:

 

pH = 0.5 (7.12 – log 0.002)

<span>pH = 4.91</span>
