The faster your moving the quicker the evaporation.

Answer:

Wind moving over a water or land surface can also carry away water vapor, essentially drying the air, which leads to increased evaporation rates.

4Fe (s) + 3 O2 (g) → 2 Fe2O3 (s)

Novay_Z [31]

Explanation:

The number acquired by an element after the lose or gain of an electron is called oxidation number.

For example, $4Fe(s) + 3O_{2}(g) \rightarrow 2Fe_{2}O_{3}(s)$

Here, oxidation number of Fe(s) is 0 and Fe in $Fe_{2}O_{3}$ is +3.

Oxidation number of O in $O_{2}(g)$ is 0 as it is present in its elemental state.

The oxidation number of O in $Fe_{2}O_{3}$ is calculated as follows.

$2(3) + 3x = 0\\6 + 3x = 0\\x = \frac{-6}{3}\\= -2$

Hence, oxidation number of O in $Fe_{2}O_{3}$ is -2.

The loss of electrons by an element or substance is called oxidation. Here, electrons are being lost by Fe(s) as an increase in oxidation state is occurring. So, Fe(s) is oxidized.

The gain of electrons by an element or substance is called reduction. Here, electrons are being added to $O_{2}$ as a decrease in its oxidation state is occurring. So, $O_{2}$ is reduced.

An element or compound which is being reduced is called oxidizing agent. Here, $O_{2}$ is the oxidizing agent.

An element or compound which is being oxidized is called reducing agent. Here, Fe(s) is the reducing agent.

What are called conductors of electricity

attashe74 [19]

Answer:

Some materials let electricity pass through them easily. These materials are known as electrical conductors. Many metals, such as copper, iron and steel, are good electrical conductors.

What is the difference between a dwarf planet and an asteroid?

svet-max [94.6K]

dwarf planet is a planetary-mass object that is neither a planet nor a natural satellite. That is, it is in direct orbit of the Sun, and is massive enough for its gravity to crush itself into a hydrostatic equilibrium shape (usually a spheroid), but has not cleared the neighborhood of other material around its orbit.

asteroids are rocks

Why is a liquid able to flow

luda_lava [24]

Since the particles can move, the liquid can flow and take the shape of its container. Some insects, such as pond-skaters, are able to walk on water without sinking. This is because the forces of attraction between the water particles pull the particles at the surface together.

Write a balanced equation for the combustion of gaseous ethane (c2h6), a minority component of natural gas, in which it combines

tatiyna

The original reaction equation is:
C2H6(g) + O2(g) → CO2 + H2O
but this is not a balanced equation, SO we have to compare the no of atoms on both sides:
1-C atoms: we have 2 atoms on the left side and 1 on the right side so we put 2CO2 instead of CO2
C2H6(g) + O2(g) → 2CO2(g) + H2O(g)
2- H atoms: we have 6 atoms on the left side and 2 atoms on the right side so we put 3H2O instead of H2O
C2H6(g) + O2(g) →2CO2(g) + 3H2O(g)
2- O atoms: we have 2 atoms on the left side and 7 atoms in left side so we put 7/2O2 instead of O2
C2H6(g) + 7/2 O2(g) → 2CO2(g) + 3H2O(g) by dividing this equation by 2
∴the final balanced equation of our reaction is:
2C2H6(g) + 7 O2(g) → 4CO2(g) + 6 H2O(g)
as
C atoms on both sides = 4
H atoms on both sides = 12
O atoms on both sides = 14
