Answer:
Explanation:
<em>Ferrous Sulphate</em><em> 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 </em><em>, Sulphur Dioxide </em><em> as well as Ferric Oxide </em><em>.</em>
<em>We can hence, frame a skeletal equation of this reaction and try to balance it.</em>
<em>Hence,</em>
<em>Now,</em>
<em>a)In order to balance it through the 'Hit &Trial Method', we'll follow a series of </em><em>steps</em><em>:</em>
<em>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 </em>.
<em>2. Now, Iron atoms, Sulphur Atoms and Oxygen atoms occur 2, 2, 8 respectively on both the sides:</em>
<em> Hence, As all the other elements as well as iron, balance, we've arrived upon our Balanced Equation :</em>
<em> </em>
<em>b) We know that, decomposition reactions are [generally] endothermic reactions in which Large Compounds </em><em>decompose </em><em>into smaller elements and compounds. Here, as Ferrous Sulphate </em><em>decomposes </em><em>into Sulphur Dioxide, Sulphur Trioxide and Ferric Oxide, the reaction that occurs here is </em><em>Decomposition Reaction.</em>
Answer:
It takes millions of years to form,
Compressing on the ocean floor.
Then one day they come to shore
and sediments they are no more.
They can sometimes tell of life before
with layers, fossils and much more! this is the rock formation
it's not a decoration .
Explanation:
The catalyst has been represented with the formula above the arrow in the chemical equation.
The catalyst has been the compound or element in the chemical reaction that helps in the lowering of the activation energy of the system and thereby leads to an increase in the rate of the reaction.
The chemical equation has been represented in the form of the chemical formula of the reactants and the products.
The catalyst has not been consumed in the chemical reaction, thus it has been represented with the formula above the arrow in the chemical equation.
