Answer:

Explanation:

volume of solution = 100 + 100 = 200 mL

mass of reaction mixture = 200 x 1.010 = 202 g

specific heat of solution mixture = 4.184 J/g-°C

heat evolved = mass x specific heat x rise in temperature

= 202 x 4.184 x 7.01

= 5924.63 J

100 mL of 1 M HCl

= .1 L of 1M HCl will contain .1 mole of HCl

.1 mole reacts with .1 mole of NH₄OH to make 5924.63 J of heat

1 mole reacts with 1 mole of NH₄OH to make 59246.3 J of heat

heat of reaction = 59246.3 J / mol

= 59.246 kJ / mol

= 59.3 kJ / mol .

Answer:

166.56g of NH3 are produced

Explanation:

The reaction of N2 with H2 to produce NH3 is:

N2 + 3H2 → 2NH3

Where 1 mole of N2 produce 2 moles of NH3

4.89 moles of N2 with excess of H2 produce:

4.89 moles N2 * (2 moles NH3 / 1 mole N2) = 9.78 moles NH3

As molar mass of NH3 is 17.031g/mol, mass of NH3 produced is:

9.78 moles * (17.031g / mol) =

Answer:

Ammonia is limiting reactant

Amount of oxygen left  = 0.035 mol

Explanation:

Masa of ammonia = 2.00 g

Mass of oxygen = 4.00 g

Which is limiting reactant = ?

Balance chemical equation:

4NH₃ + 3O₂     →     2N₂ + 6H₂O

Number of moles of ammonia:

Number of moles = mass/molar mass

Number of moles = 2.00 g/ 17 g/mol

Number of moles = 0.12 mol

Number of moles of oxygen:

Number of moles = mass/molar mass

Number of moles = 4.00 g/ 32 g/mol

Number of moles = 0.125 mol

Now we will compare the moles of ammonia and oxygen with water and nitrogen.

                      NH₃          :            N₂

                        4             :             2

                      0.12           :           2/4×0.12 = 0.06

                      NH₃         :            H₂O

                        4            :             6

                        0.12       :           6/4×0.12 = 0.18

                       O₂            :            N₂

                        3             :             2

                      0.125        :           2/3×0.125 = 0.08

                        O₂           :            H₂O

                        3              :             6

                        0.125       :           6/3×0.125 = 0.25

The number of moles of water and nitrogen formed by ammonia are less thus ammonia will be limiting reactant.

Amount of oxygen left:

                        NH₃          :             O₂

                           4            :              3

                           0.12       :          3/4×0.12= 0.09

Amount of oxygen react = 0.09 mol

Amount of oxygen left  = 0.125 - 0.09 = 0.035 mol

Answer:

An alloy is a mixture or metallic-solid solution composed of two or more elements. Examples of alloys include materials such as brass, pewter, phosphor bronze, amalgam, and steel. Complete solid solution alloys give single solid phase microstructure. Partial solutions give two or more phases that may or may not be homogeneous in distribution, depending on thermal history. An alloy’s properties are usually different from those of its component elements.

Steel: Steel is an alloy whose major component is iron.

Alloy constituents are usually measured by mass. An alloy is usually classified as either substitutional or interstitial, depending on its atomic arrangement. In a substitutional alloy, the atoms from each element can occupy the same sites as their counterpart. In interstitial alloys, the atoms do not occupy the same sites. Alloys can be further classified as homogeneous (consisting of a single phase), heterogeneous (consisting of two or more phases), or intermetallic (where there is no distinct boundary between phases).

Alloying a metal involves combining it with one or more other metals or non-metals, which often enhances its properties. For example, steel is stronger than iron, its primary element. Physical properties (density, reactivity, conductivity) of an alloy may not differ greatly from those of its constituent elements, but its engineering properties (tensile strength and shear strength) may be substantially different.

Answer:

V = 22.36 L

Explanation:

Given data:

Mass of oxygen = 18.0 g

Temperature = 350 K

Pressure = 0.720 atm

Volume of gas = ?

Solution:

Number of moles of oxygen :

Number of moles = mass/molar mass

Number of moles = 18.0 g/ 32 g/mol

Number of moles = 0.56 mol

Volume of oxygen:

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

0.720 atm × V =  0.56 mol × 0.0821 atm.L/ mol.K   × 350 K

V = 16.1 atm.L /0.720 atm

Fission breaks apart nuclei

Fusion puts them together.

======================================================

Explanation:

The term "fission" is related to the term "fissure" which means "a cut or divide", often describing a geologic feature of the earth (eg: a crack in the rock).

Fusion is the idea of putting things together, which is the opposite of fission. The term doesn't have to apply to nuclear fusion. It could be something like the fusing of two ideas to create one new idea.

Answer:

52.068 amu

Explanation:

To calculate the average atomic mass of chromium, you have to first multiply the abundance of an isotope with its mass.

49.946 × 0.0435 = 2.173

51.941 × 0.838 = 43.527

52.941 × 0.0235 = 1.244

53.939 × 0.095 = 5.124

Next, add up all of the values, and you will get the average atomic mass.

2.173 + 45.527 + 1.244 + 5.124 = 52.068 amu

Answer:

The number of moles of HCl in the 250 mL volumetric flask is 0.003 moles

Explanation:

Firstly, we solve for the concentration of acid using the formula

CaVa/CbVb = nₐ/nb

where Ca is the concentration of acid

Cb is the concentration of base

Va is the volume of acid

Vb is the volume of base

nₐ is the number of moles of acid (from the equation)

nb is the number of moles of base (from the equation)

Ca × 250/0.09876 × 29.59 = 1/1

Ca = 0.09876 × 29.59/250

Ca = 0.012 M

To determine the number of moles of HCl acid present in the 250 ml volumetric flask, the formula for molarity is used

Molarity = number of moles ÷ volume (in liter or dm³)

Volume needs to be converted to liter; 250 ml ⇒ 0.25 L

Molarity of the acid is 0.012 M

From the formula above, number of moles = molarity × volume (in liter)

number of moles = 0.012 × 0.25

number of moles of acid = 0.003 moles
