_____ is a measure of the average kinetic energy of a gas.

nikitadnepr [17]

Answer:

$a)\ 2FeSO4 \xrightarrow{\text{Heat}} SO_3+SO_2+Fe_2O_3\\b)\ Decomposition\ Reaction$

Explanation:

Ferrous Sulphate $(FeSO4)$ is generally found as Lime-Green Crystals. On heating, these crystals almost immediately turn white-yellow. They then, break down to produce an anhydrous mixture of Sulphur Trioxide $(SO_3)$ , Sulphur Dioxide $(SO_2)$ as well as Ferric Oxide $(Fe_2O_3)$ .

We can hence, frame a skeletal equation of this reaction and try to balance it.

Hence,

$FeSO4 \xrightarrow{\text{Heat}} SO_3+SO_2+Fe_2O_3$

Now,

a)In order to balance it through the 'Hit &Trial Method', we'll follow a series of steps:

1. First, lets compare the number of Fe (Iron) atoms on the RHS and LHS. We find that, the no. of Fe Atoms on the RHS is twice the number of Fe Atoms on the LHS. We hence, add a co-effecient 2 beside $FeSO_4$ .

2. Now, Iron atoms, Sulphur Atoms and Oxygen atoms occur 2, 2, 8 respectively on both the sides:

Hence, As all the other elements as well as iron, balance, we've arrived upon our Balanced Equation :

$2FeSO4 \xrightarrow{\text{Heat}} SO_3+SO_2+Fe_2O_3$

b) We know that, decomposition reactions are [generally] endothermic reactions in which Large Compounds decompose into smaller elements and compounds. Here, as Ferrous Sulphate decomposes into Sulphur Dioxide, Sulphur Trioxide and Ferric Oxide, the reaction that occurs here is Decomposition Reaction.

In a wave, energy is...

Taya2010 [7]

Answer:

Wave energy is the transport and capture of energy by ocean surface waves. The energy captured is then used for all different kinds of useful work, including electricity generation, water desalination, and pumping of water.

instrucions classify the following reactions as synthesis, decomposition,single replacement, double replacement, or combustion.

My name is Ann [436]

Answer:

There are no specific equations but here what i can give you:

1. Synthesis -- A synthesis reaction is a chemical change in which two or more substances react to form a single new substance.

In all synthesis reactions, there is a single product that is a compound!

2. Decomposition -- A decomposition reaction is a chemical change in which a single compound breaks down into two or more simpler products. (This is the opposite of synthesis reactions!)

Most decomposition reactions require energy in the form of heat, light, and electricity.

3. Single Replacement -- A single-replacement reaction is a chemical change in which one element replaces a second element in a compound. You can identify a single-replacement reaction by noting that both the reactants and the products consist of an element and a compound.

4. Double Replacement -- A double-replacement reaction is a chemical change involving an exchange of positive ions between two compounds.

For a double replacement reactions to occur, one of the following is usually true:

- One of the products is only slightly soluble and precipitates from solutions.

- One of the products is a gas.

- One product is a molecular compound such as water.

5. Combustion -- A combustion reactions is a chemical change in which an element or a compound reacts with oxygen, often producing energy in the form of heat or light.

A combustion reactant always involves oxygen as a reactant. (If the supply of oxygen is limited, then the combustion will not be complete.)

The other reactant is a hydrocarbon, which is a compound composed of hydrogen and carbon and the complete combustion of a hydrocarbon produces CO2 and H2O.

Hydrocarbons include methane, propane, and butane.

I really hope this helps you!

A new island formed by volcanic action may eventually become populated with living organism as a result of?

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:
