If 5.32 mols N2 and 15.8 mols H2 react together, what mass NH3 can be

Chemistry

hodyreva [135]3 years ago

Answer:

2.87 gram

N2 is the limiting agent

Explanation:

We will find out if there is sufficient N2 and h2 to produce NH3

a) For 2.36 grams of N2

Molar mass of N2 = 28.02

Number of moles of N2 in 2.36 grams = 2.36/28.02

Mass of NH3 = 17.034 g

Now NH3 produced form 2.36 grams of N2 =  

2.36/28.02 * 2 * 17.034 = 2.87 g NH3

b) For 1.52 g of H2  

NH3 produced = 1.52/2.016 * (2/3) * 17.034 = 8.56

N2 Is not enough to produce 2.87 g of NH3 and also H2 is not enough to make 8.56 g of NH3.  

N2 is the limiting agent as it has smaller product mass

Background research about water purification and filtration!!!
notka56 [123]

Answer: It's a modern-day engineering challenge to remove human-made contaminants from

drinking water. After a quick review of the treatment processes that municipal water

goes through before it comes from the tap you will learn about the still-present

measurable contamination of drinking water due to anthropogenic (human-made)

chemicals. Substances such as prescription medication, pesticides and hormones are

detected in the drinking water supplies of American and European metropolitan cities.

The engineering design process can be used to design solutions for a real-world

problem (contaminated water) that could affect health.

Engineering Connection

The water that comes from our faucets has passed through a complex system designed

by many different types of engineers. Civil, chemical, electrical, environmental,

geotechnical, hydraulic, structural and architectural engineers all play roles in the

design, development and implementation of municipalities' drinking water supplies and

delivery systems. Hydraulic engineers design systems that safely filter the water at a

rate needed to supply a specific region and population. Chemical engineers precisely

determine the amounts and types of chemicals added to source water for coagulation

and decontamination to make the water safe to drink and not taste bad. Even so,

modern pharmaceutical and agricultural practices persist in contaminating our water

supplies.

How can the ph scale tell you if a substance is an acid a base or neutral?
Pavel [41]
The Ph  scale  can tell you if a substance  is an acid a base or neutral  by



  a Ph scale  runs from a Ph of 1-14. if a substance has  a Ph less than 7 (Ph<7)  the substance is said to be a an acid

if  a substance has a ph greater than  7 (Ph>7) the substance is said to be a base

if a  substance has a Ph equal to 7(Ph=7)  the substance is said to be neutral

The value of ΔG° at 181.0 °C for the formation of calcium chloride from calcium metal and chlorine gas is ________ kJ/mol. At 25
aleksandr82 [10.1K]

Answer:

\Delta G^{0} at 181.0 ^{0}\textrm{C} is -723.3 kJ/mol.

Explanation:

We know, \Delta G^{0}=\Delta H^{0}-T\Delta S^{0}

where, T is temperature in kelvin.

Let's assume \Delta H^{0} and \Delta S^{0} does not change in the temperature range 25.0 ^{0}\textrm{C}  - 181.0 ^{0}\textrm{C}.

181.0^{0}\textrm{C} = (273+181.0) K = 454.0 K

Hence, at 181.0 ^{0}\textrm{C}, \Delta G^{0}=(-795.8kJ/mol)-[(454.0 K)\times (-159.8\times 10^{-3}kJ/K.mol)]

        = -723.3 kJ/mol

A chemical reaction in which one element replaces another element in a compound can be catergorized as a
Gwar [14]

Answer:

\huge\boxed{\sf Single \ displacement \ reaction}

Explanation:

<h2><u>Displacement reaction:</u></h2>
  • A reaction in which an element displaces or replaces another element of a compound is called a displacement reaction.
<h3><u>Types:</u></h3>

There are 2 types:

<h3><u>1. Single displacement reaction:</u></h3>
  • If one element displaces 1 other element of a compound, it is called single displacement reaction.
  • <u>Example</u>:  CuSO_4 +Fe \longrightarrow \ FeSO_4 + Cu
  • Here, 1 element (Fe) displaces 1 other element (Cu) of a compound.
<h3><u>2. Double displacement reaction:</u></h3>
  • If two elements in two compounds displace one another, it is called double displacement reaction.
  • <u>Example:</u> CuSO_4+NaOH \longrightarrow Cu(OH)_2 + Na_2SO_4
  • Here, Copper and sodium both displace each other.
