In a liquid, particles are close together but can move in any direction. They won't keep a definite shape like solids do.
Answer:
Option D. Iron and sulfur react to form iron sulfide
Explanation:
Reaction of iron with sulphur is a chemical property and not a physical property.
Glucose can be converted into ethanol, carbon dioxide and energy (usually in the form of heat).
Using chemical formulas, this can be illustrated as follows:
Glucose = Ethanol + Carbon Dioxide + Energy
C6H12O6 = 2C2H5OH + 2CO2 + Energy
From the periodic table:
molecular mass of carbon = 12 grams
molecular mass of oxygen = 16 grams
molecular mass of hydrogen = 1 gram
Therefore:
molar mass of glucose = 6(12) + 12(1) + 6(16) = 180 grams
molar mass of ethanol = 2(12) + 5(1) + 16 + 1 = 46 grams
molar mass of carbon dioxide = 1(12) + 2(16) = 44 grams
Based on the conversion equation, each one mole of glucose converts into two moles of ethanol and two moles of carbon dioxide.
Therefore, each 180 grams of glucose converts into 46 x 2 = 92 grams of ethanol and 44 x 2 = 88 grams of carbon dioxide in addition to energy.
To calculate the mass of ethanol and carbon dioxide produced from 200 grams of glucose, we will simply use cross multiplication as follows:
mass of ethanol = (200 x 92) / 180 = 102.2 grams
mass of carbon dioxide = (200 x 88) / 180 = 97.7 grams
Total mass of ethanol and carbon dioxide = 102.2 + 97.7 = 199.9 grams
Answer:
4Fe + 3O₂ → 2Fe₂O₃
Explanation:
The chemical reaction is given as:
Fe + O₂ → Fe₂O₃
To balance an equation implies that the number of atoms and moles must be conserved.
using the coefficients a,b and c, let use a mathematical approach to balance the expression;
aFe + bO₂ → cFe₂O₃
Conserving Fe: a = 2c
O: 2b = 3c
let c = 1, a = 2 , b = 
multiply through by 2 ;
a = 4, b = 3 and c = 2
4Fe + 3O₂ → 2Fe₂O₃
