Answer:
% composition of glucose = 85 %
Explanation:
Given Data
moles of glucose (C₆H₁₂O₆) = 1.3 mole
Total mass of mixture = 276 g
percent composition of glucose (C₆H₁₂O₆) = ?
Solution
Number of moles are given so we find out the mass of C₆H₁₂O₆
<em>mass = moles × molar mass</em>
Molar mass of glucose = 180.156 g/mol
mass = 1.3 mol × 180.156 g/mol
mass = 234.2 g
Now we find out the percent composition of glucose
% composition = (mass of compound ÷ mass of mixture) × 100
% composition = ( 234.2 g ÷ 276 g) × 100
% composition = 0.85 × 100
% composition = 85 %
<span>Thermal energy is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.</span>
<span>Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another, and the transfer or flow due to the difference in temperature between the two objects is called heat.</span>
<span>The kinetic temperature is the variable needed for subjects like heat transfer, because it is the translational kinetic energy which leads to energy transfer from a hot area (larger kinetic temperature, higher molecular speeds) to a cold area (lower molecular speeds) in direct collisional transfer.</span>
Answer:
The oxidation number of the metal decreases
2 Al + Fe₂O₃ → Al₂O₃ + 2 FeO
The metal element iron, is reduced from Fe⁺³ in Fe₂O₃ to Fe⁺² in FeO
Explanation:
When an element gains electron, the element becomes reduced, hence when a metal is reduced, the metal gains electrons, which reduces the oxidation number of the metal
An example of a metal being reduced is;
2 Al + Fe₂O₃ → Al₂O₃ + 2 FeO
In the above reaction, the iron (III) oxide is reduced to iron (II) oxide by aluminium metal.
