Sorting the chemical elements in order from least reactive to most reactive, we have:

1. Fluorine (F).

2. Arsenic (As).

3. Antimony (Sb).

4. Silicon (S).

<u>Given the following chemical elements:</u>

  • Antimony (Sb).
  • Silicon (S).
  • Fluorine (F).
  • Arsenic (As).

Reactivity can be defined as a chemical property which determines how readily a chemical element <u>bonds</u> with other chemical elements, in order to form a new chemical compound.

Generally, the ability of a chemical element to bond with other chemical elements is largely (highly) dependent on the number of valence electrons it has in the outermost shell of its atomic nucleus.

As a general rule, chemical elements that are having <u>fewer</u> number of valence electrons are the most reactive while those having <u>higher</u> valence electrons are least reactive.

Also, chemical reactivity <u>decreases</u> down a group on the periodic table.

Based on the periodic table, the valency for the given chemical elements are:

  • <u>Antimony (Sb):</u> 5 valence electrons.
  • <u>Silicon (S):</u> 4 valence electrons.
  • <u>Fluorine (F):</u> 7 valence electrons.
  • <u>Arsenic (As):</u> 5 valence electrons.

In conclusion, sorting the chemical elements in order from least reactive to most reactive, we have:

1. Fluorine (F).

2. Arsenic (As).

3. Antimony (Sb).

4. Silicon (S).

A gas cylinder of volume 5.00 l contains 1.00 g of ar and 0.500 g of ne. the temperature is 275 k. find the partial pressure of
amid [387]
<span>11.3 kPa The ideal gas law is PV = nRT where P = Pressure V = Volume n = number of moles R = Ideal gas constant (8.3144598 L*kPa/(K*mol) ) T = Absolute temperature We have everything except moles and volume. But we can calculate moles by starting with the atomic weight of argon and neon. Atomic weight argon = 39.948 Atomic weight neon = 20.1797 Moles Ar = 1.00 g / 39.948 g/mol = 0.025032542 mol Moles Ne = 0.500 g / 20.1797 g/mol = 0.024777375 mol Total moles gas particles = 0.025032542 mol + 0.024777375 mol = 0.049809918 mol Now take the ideal gas equation and solve for P, then substitute known values and solve. PV = nRT P = nRT/V P = 0.049809918 mol * 8.3144598 L*kPa/(K*mol) * 275 K/5.00 L P = 113.8892033 L*kPa / 5.00 L P = 22.77784066 kPa Now let's determine the percent of pressure provided by neon by calculating the percentage of neon atoms. Divide the number of moles of neon by the total number of moles. 0.024777375 mol / 0.049809918 mol = 0.497438592 Now multiply by the pressure 0.497438592 * 22.77784066 kPa = 11.33057699 kPa Round the result to 3 significant figures, giving 11.3 kPa</span>

The density of air under ordinary conditions at 25°C is 1.19 g/L. How many kilograms of air are in a room that measures 10.0 ft
Lunna [17]

Answer: The mass of air present in the room is 37.068 kg

Explanation :  Given,

Length of the room = 10.0 ft

Breadth of the room = 11.0 ft

Height of the room = 10.0 ft

To calculate the volume of the room by using the formula of volume of cuboid, we use the equation:

V=lbh

where,

V = volume of the room

l = length of the room

b = breadth of the room

h = height of of the room

Putting values in above equation, we get:

V=10.0ft\times 11.0ft\times 10.0ft=1100ft^3=31148.53L

Conversion used : 1ft^3=28.3168L

Now we have to calculate the mass of air in the room.

Density=\frac{Mass}{Volume}

1.19g/L=\frac{Mass}{31148.53L}

Mass=37066.7507g=37.068kg

Conversion used : (1 kg = 1000 g)

Therefore, the mass of air present in the room is 37.068 kg
