Explain Charles law​

Chemistry

"Charles Law" is the relationship between "volume-temperature" (V ∝ T).

<u>Explanation</u>:  

Charles Law is basically volume-temperature relationship (V ∝ T). French scientist “Jacques Charles” in 1787 studied effect of temperature on the volume of gases at constant pressure, which described how gases manage to expand when heated. Law stated as “At constant pressure, the volume of a given "mass" of a gas decreases or increases by 1/273 of its volume at 0^{\circ} \mathrm{C} for each one degree rise or fall in temperature”. Formula derived from law is as follows: \mathbf{V}_{\mathbf{t}}=\mathbf{V}_{0}[\mathbf{1}+\mathbf{t} / \mathbf{2} 7 \mathbf{3}] here {V}_{0} is volume of given mass of a gas at 0^{\circ} \mathrm{C}, {V}_{t} is its volume at any temperature t^{\circ} \mathrm{C}. Application of Charles law is hot air balloons.

How can I balance this equation? ____ KClO3 ---&gt; ____ KCl + ____ O2
tensa zangetsu [6.8K]
__ KClO₃ → __ KCl + __ O₂

Left Side:
1 K
1 Cl
3 O

Right Side:
1 K
1 Cl
2 O

Since the least common multiple of 3 and 2 is 6, we need to multiply the compound with 2 oxygen by 3 and the compound with 3 oxygen by 2.

This gives us 2KClO₃ → __ KCl + 3O₂.

However, this equation is still not balanced.

Left Side:
2 K
2 Cl
6 O

Right Side:
1 K
1 Cl
6 O

In order to balance the K and Cl, we need to multiply the KCl compound on the right side by 2.

2KClO₃ → 2KCl + 3O₂

Does the reaction of hydrogen produce any products that negatively affect the environment?
klasskru [66]

The answer is NO. During combustion of hydrogen, water is produced as an end product. The chemical formulae for combustion of hydrogen are:

2H2 + O2 -->2 H2O

another advantage is that the whole of the fuel load is combusted hence little wastage. This has made the fuel advantageous in its use as rocket fuel since there is no baggage fuel.

Answer:

Ecological succession

Succession as progressive change in an ecological community. Primary vs. secondary succession. The idea of a climax community.

Key points

Succession is a series of progressive changes in the composition of an ecological community over time.

In primary succession, newly exposed or newly formed rock is colonized by living things for the first time.

In secondary succession, an area previously occupied by living things is disturbed—disrupted—then recolonized following the disturbance.

Introduction

Have you ever looked at a landscape with a complex, diverse community of plants and animals—such as a forest—and wondered how it came to be? Once upon a time, that land must have been empty rock, yet today, it supports a rich ecological community consisting of populations of different species that live together and interact with one another. Odds are, that didn't happen overnight!

Ecologists have a strong interest in understanding how communities form and change over time. In fact, they have spent a lot of time observing how complex communities, like forests, arise from empty land or bare rock. They study, for example, sites where volcanic eruptions, glacier retreats, or wildfires have taken place, clearing land or exposing rock.

In studying these sites over time, ecologists have seen gradual processes of change in ecological communities. In many cases, a community arising in a disturbed area goes through a series of shifts in composition, often over the course of many years. This series of changes is called ecological succession.

Succession

Ecological succession is a series of progressive changes in the species that make up a community over time. Ecologists usually identify two types of succession, which differ in their starting pExplanation:

Determine the total time that must elapse until only ¼ of an original sample of the radioisotope Rn-222 remains unchanged.
Arte-miy333 [17]

Answer:

7.6 days

Explanation:

Radon is a radioactive element and Radon-222 is it's most stable isotope. The half-life of Radon-222 has been found to be approximately 3.8 days.

Let, the initial amount of the Rn-222 = 1 = A

Final amount = \frac{1}{4} = A'

We will use the following relation for calculating time elapsed in the decay

A' = A(\frac{1}{2} )^\frac{t}{t_1_/_2}  }

Thus,

\frac{1}{4} =1(\frac{1}{2} )^\frac{t}{3.8}

We can write is as,

(\frac{1}{2} )^2=(\frac{1}{2} )^\frac{t}{3.8}

Since the base in both sides are equal, powers can also be equal and thus,

2=\frac{t}{3.8}

So, t = 7.6 days
