Atoms with very high electronegativity exhibit a strong electron-attracting ability, high ionization energy, small atomic radius, the ability to form strong covalent bonds, a polarizing effect on chemical bonds, and can participate in hydrogen bonding.

Strong electron-attracting ability: Electronegativity is a measure of an atom's ability to attract electrons towards itself in a chemical bond. Atoms with high electronegativity have a strong pull on electrons, meaning they attract and hold electrons tightly.

High ionization energy: Ionization energy is the energy required to remove an electron from an atom or ion. Atoms with high electronegativity tend to have high ionization energies because they tightly hold their valence electrons and require a significant amount of energy to remove them.

Small atomic radius: Electronegativity generally increases as the atomic radius decreases. Atoms with high electronegativity tend to have smaller atomic radii, as the positive charge in the nucleus pulls the electrons closer, resulting in a stronger electron-attracting ability.

Ability to form strong covalent bonds: Atoms with high electronegativity can form strong covalent bonds by sharing electrons with atoms of lower electronegativity. This results in the formation of stable molecules with shared electron pairs.

Polarizing effect on chemical bonds: When atoms with high electronegativity are involved in a bond with atoms of lower electronegativity, they exert a stronger pull on the shared electrons, resulting in a polar bond. This leads to the development of partial positive and partial negative charges within the molecule.

Participation in hydrogen bonding: Atoms with high electronegativity, such as oxygen and nitrogen, can participate in hydrogen bonding. Hydrogen bonding occurs when a hydrogen atom is bonded to an electronegative atom and interacts with another electronegative atom through a weak electrostatic attraction.

Answer: Have a blessed day

Explanation:

Water Cycle: Component # 1. Evaporation:

Evaporation is the process where a liquid changes from its liquid state to a gaseous state. Liquid water becomes water vapour. Temperature is the primary factor for evaporation.

During the water cycle the water of the oceans and freshwater bodies, such as lakes and rivers, is warmed by the sun and evaporates. During the process of evaporation, impurities in the water are left behind. As a result, the water that goes into the atmosphere is cleaner than it was on Earth.

Water Cycle: Component # 2. Condensation:

Condensation is the opposite of evaporation. Condensation is the process where a gas is changed into a liquid. Condensation occurs when the temperature of the vapour decreases.

The water droplets formed from condensation are very small and they remain suspended in the atmosphere. There millions of droplets of suspended water form clouds in the sky or fog at ground level. Water condenses into droplets only when there are small dusts particles present around.

Water Cycle: Component # 3. Precipitation:

When the temperature and atmospheric pressure are right, the small droplets of water in clouds form larger droplets or raindrops and it is called precipitation. The raindrops fall to earth.

As a result of evaporation, condensation and precipitation, water travels from the surface of the Earth goes into the atmosphere, and returns to Earth again.

Water Cycle: Component # 4. Surface Runoff:

Much of the water that returns to Earth as precipitation runs off the surface of the land and flows down-hill into streams, rivers, ponds and lakes. Small streams flow into the ocean. Surface runoff is an important part of the water cycle because, through surface runoff, much of the water returns again to the oceans, where a great deal of evaporation occurs.

Water Cycle: Component # 5. Infiltration:

ADVERTISEMENTS:

Infiltration is an important process where rain water soaks into the ground, through the soil and underlying rock layers. Some of this water ultimately returns to the surface at springs or in low spots downhill. Some of the water remains underground and is called groundwater.

As the water infiltrates through the soil and rock layers, many of the impurities in the water are filtered out. This filtering process helps in cleaning of the water.

Water Cycle: Component # 6. Transpiration or Evapotranspiration:

This is performed by plants. As plants absorb water from the soil, the water moves from the roots through the stems to the leaves. Once the water reaches the leaves, some of it evaporates from the leaves, adding to the amount of water vapour in the air. This process of evaporation through plant leaves is called transpiration. In large forests, an enormous amount of water will transpire through leaves.

The hydrogen bonding between the water molecules affect the properties of the water as they make the molecules stick together which arises the property of the cohesion and the surface tension.

The hydrogen bonding forms between the water molecules as they have the slightly positive charge on the hydrogen atom and the slightly negative charge on the oxygen atom. The bond present between the hydrogen and the oxygen is the covalent bond. The oxygen is more electronegative than the hydrogen this creates the partial positive and the partial negative charges.

Answer: The mass of \(FeO\) required is 14.37 g

Explanation:

Molarity is calculated by using the equation:

\(\text{Molarity}=\frac{\text{Moles}}{\text{Volume}}\) ......(1)

We are given:  

Molarity of iron (II) sulfate = 1 M

Volume of solution = 200 mL = 0.200 L (Conversion factor: 1 L = 1000 mL)

Putting values in equation 1, we get:

\(\text{Moles of }FeSO_4=(1mol/L\times 0.200L)=0.200mol\)

The chemical equation for the reaction of FeO with sulfuric acid follows:

\(FeO+H_2SO_4\rightarrow FeSO_4+H_2O\)

By stoichiometry of the reaction:

If 1 mole of iron (II) sulfate is produced by 1 mole of FeO

So, 0.200 moles of iron (II) sulfate will produce = \(\frac{1}{1}\times 0.200=0.200mol\) of FeO

The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:

\(\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}\)

We know, molar mass of \(FeO\) = 71.84 g/mol

Putting values in above equation, we get:

\(\text{Mass of }FeO=(0.200mol\times 71.84g/mol)=14.37g\)

Hence, the mass of \(FeO\) required is 14.37 g

Answer: D. the quantity of heat that is required to 1 g of the sample 1°C (Kelvin) at a constant pressure

Explanation:

Specific heat capacity is defined as the quantity of heat required to raise the temperature of one gram of a substance by one degree Celsius (Kelvin) at a constant pressure.

It is dependent on temperature, especially for gases, and is related to intermolecular forces. The higher the specific heat of a substance, the more energy is needed to raise the temperature of the substance.

You can multiply this value by the mass of a given substance (g) and the change in temperature (degC) to find the amount of heat gained or lost (Joules).

t = 57 min., Therefore, we can say that it takes 57 minutes for cyclopropane's partial pressure to drop from 1 atm to 0.125 atm at 500°C.

Propene (CH3CH=CH2) is produced by the isomerization of cyclopropane, which is a first-order process. A sample of cyclopropane converts to propene in 79 minutes at 760 K.

The reaction is a first-order reaction because it is an isomerization reaction, and its rate constant is expressed in terms of minutes. The sum of the powers or exponents that the concentration terms are raised in the rate law expression can be used to define the order of a reaction.
