Answer: The energy of the infrared radiation is [tex]19.8\times 10^{-21}J[/tex]

Explanation:

The relationship between wavelength and energy of the wave follows the equation:

[tex]E=\frac{hc}{\lambda}[/tex]

E= energy

[tex]\lambda [/tex] = wavelength of the wave  =[tex]1.0\times 10^{-5}m[/tex]

h = Planck's constant  = [tex]6.626\times 10^{-34}Js[/tex]

c = speed of light = [tex]3\times 10^8m/s[/tex]

[tex]E=\frac{6.626\times 10^{-34}Js\times 3\times 10^8m/s}{1.0\times 10^{-5}m}[/tex]

[tex]E=19.8\times 10^{-21}J[/tex]

Thus energy of the infrared radiation is [tex]19.8\times 10^{-21}J[/tex]

Answer:

Q8) True

Q9) First ionization energy

Q10) A metal oxide

Explanation:

One of the properties of group one elements (alkali metals) is that they combine with water to form basic solutions. E.g 2Na(s)+2H2O(l)→2NaOH(aq)+H2​(g).

An inverse relationship exists between the distance of the outermost electron in the atom from the nucleus and the first ionization energy. As the distance between the outermost electron and the nucleus in group 17 elements increases, their first ionization energies decreases accordingly.

Group 1 elements react with oxygen to yield the corresponding metal oxides. E.g  4 Na + O2 --> 2 Na2O

Answer:

The correct answer is Pu, 234.

Explanation:

In the given case, let us consider the reactant as X. Now the mass number (balanced) on both the sides will be,

Mass of X = Mass of Molybdenum + Mass of Tin + Mass of neutrons

M = 1 * 103 + 1 * 131 + 2 * 0

M = 234

Now the atomic number (balanced) on both the sides,

Atomic number of X = Atomic number of Molybdenum + Atomic number of Tin + Atomic number of neutrons

A = 1*42 + 1*50 + 2*1

A = 94

The atomic number 94 is for the element Plutonium, whose symbol is Pu. Thus, the reactant is 234-Pu.

A 1.00 g sample of NH4NO3 is decomposedin a bomb calorimeter. The temperature increases by 6.12°C. What is the molar heat of decomposition for ammonium nitrate?

Molar mass, NH4NO3 80.0 g/mol

Calorimeter Constant   1.23 kJ/°C

Answer:

the molar heat of decomposition for ammonium nitrate is - 602.4 kJ/mol

Explanation:

Given that;

change in temperature ΔT = 6.12 °C

Calorimeter Constant C = 1.23 kJ/°C

Molar mass, NH4NO3 = 80.0 g/mol

we know that;

Heat gained by the calorimeter (Q1) = Heat lost by the decomposition of NH4NO3 (Q2)

Q1 = C × ΔT

Q1 = (1.23 kJ/K) × (6.12 K) = 7.53 kJ

Q value we get becomes negative since we are talking about reaction and not calorimeter

hence

Q1 = - 7.53 kJ

now

1 g NH4NO3 decomposed, - 7.53 kJ of heat is released

so if 80 g which is 1 mol NH4NO3 decompose, the heat will be;

(80 g/mol x -7.53 kJ) / 1 g = - 602.4 kJ/mol

Therefore the molar heat of decomposition for ammonium nitrate is - 602.4 kJ/mol

In a climatological sense, dryness is a function of both annual rainfall and evaporation

Answer:

160 g

Explanation:

The chemical equation is:

C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + 6H₂O(g)

According to the equation, 1 mol of glucose (C₆H₁₂O₆) reacts with 6 moles of O₂. We calculate the masses of the reactants from the molar masses of the chemical elements:

1 mol C₆H₁₂O₆ = (6 x 12 g/mol)+ (12 x 1 g/mol) + (6 x 16 g/mol) = 180 g

6 mol O₂ = 6 x (2 x 16 g/mol) = 6 x 32 g/mol = 192 g

So, 180 g of C₆H₁₂O₆ reacts with 192 g of O₂. The stoichiometric ratio is 192 g O₂/180 g C₆H₁₂O₆. To calculate the grams of O₂ needed to react with 150 g of C₆H₁₂O₆ we can simply multiply the stoichiometric ratio by the grams of C₆H₁₂O₆:

150 g C₆H₁₂O₆ x 192 g O₂/180 g C₆H₁₂O₆ = 160 g O₂

Therefore, 160 grams of O₂ are needed to fully react with 150 g of glucose.

Answer:

amount

Explanation:

Under the postulate of Boyle's law, both temperature and amount(number of moles) are kept constant.

  According to Boyle's law "the volume of a fixed mass of gas varies inversely as the pressure changes if the temperature is constant"

 Based on the premise of this law, both temperature and amount of substance is kept constant.

Answer:

Explanation:

One that forms over the Indian Ocean is called a maritime tropical air mass and is warm and humid. Air masses are classified on weather maps using two or three letters. A lowercase letter describes the amount of moisture in the air mass: m for maritime (moist) and c for continental (dry).

The letter 'c' of an air mass represents moisture content.

An air mass can be described as a volume of air defined by its humidity and temperature. Air masses are classified depending on latitude and their continental or maritime source regions. Warmer air masses are deemed tropical while Colder air masses are termed polar or arctic.

The maritime and monsoon air masses are moist while Continental and superior air masses are dry. When an air mass will move away from its source region, water bodies and underlying vegetation can quickly modify its character.

The first letter "c" represents its moisture properties in continental air masses (dry) while "m" represents maritime air masses. The letter "T" stands for Tropical, "A" stands for Arctic or Antarctic,  "E" stands for Equatorial, "P" stands for Polar, "M" stands for monsoon, and "S" stands for adiabatically drying and warming air.

Answer:

2.9 g/cm³

Explanation:

From the question given above, the following data were obtained:

Mass = 236.376 g

Volume = 81.5 cm³

Density =?

Density can be defined as the mass of a substance per unit volume of the substance. It can be expressed mathematically as:

Density = mass /volume

With the above formula, we can obtain the density of the object as shown below:

Mass = 236.376 g

Volume = 81.5 cm³

Density =?

Density = mass /volume

Density = 236.376 / 81.5

Density = 2.9 g/cm³

Thus, the density of the object is 2.9 g/cm³

Answer:

0.491 atm

Explanation:

Initial volume V1 = 571.5 mL = 0.5715 L

Initial Pressure P1 = 0.944 atm

Initial Temperature T1 = 10 oC + 273 = 283 K (Converting to kelvin units)

Final Temperature T2 = 32 oC + 273 = 305K (Converting to kelvin units)

Final volume V2 = 1.183 L

Final Pressure P2 = ?

These parameters related by the combined gas law;

P1V1 / T1   = P2V2 / T2

Mke P2 subject of formular;

P2 = P1 V1 T2 / V2 T1

P2 = 0.944 * 0.5715 * 305  /  1.183 * 283

P2 = 0.491 atm

Answer:

hydrogenation

Explanation:

Liquid vegetable oils are converted to solid fats such as margarine by a process known as hydrogenation.

Commercial production of margarine requires the hydrogenation of liquid oil at a relatively high temperature and pressure and in the presence of a catalyst. During the process, a solid catalyst (usually, nickel) is added to a preheated liquid vegetable oil before the dispersion of the hydrogen gas. The polyunsaturated vegetable oil, thus, becomes saturated or partially saturated in the process. The quality of the final product depends on the degree of hydrogenation or saturation.

The process of hydrogenation turns liquid vegetable oils into solid fats like margarine. therefore, the correct option is option B.

Unsaturated molecules undergo a chemical reaction called hydrogenation in which hydrogen gas is added. Unsaturated fats and oils are frequently transformed into saturated forms, which makes them more stable and solid at room temperature. Margarine, shortenings, and other solid fats are frequently made using this method. In order to increase stability, decrease reactivity, or change the physical and chemical properties of organic compounds, hydrogenation can also be employed to diminish or eliminate double or triple bonds in such molecules.
