How is stoichiometery used to calculate energy absorbed when a mass of a solid melts?
Stoichiometry can be used to calculate the energy absorbed when a mass of a solid melts by considering the heat energy required to overcome the intermolecular forces holding the solid together. By using the heat capacity of the solid, the mass of the solid, and the enthalpy of fusion for the substance, stoichiometry can help determine the amount of energy needed for the solid to melt.
What is meant by stoichiometry?
Stoichiometry is the calculation of quantitative relationships in chemical reactions. It involves determining the amount of reactants needed to produce a certain amount of products and vice versa, based on the balanced chemical equation. It helps in understanding the proportion of substances involved in a reaction.
How do you know which unit of conversion factor must be a conversion factor?
Assuming you are talking about stoichiometery a conversion factor is often a number with two units. For example a conversion factor could be Miles per hour (Miles/hour). If you had miles and needed to convert to hours you would multiply the miles by Hours/miles so that the miles would be canceled out (miles/miles = 1). Then your units left would be hours. Or vice versa. There are other factors like this in chemistry like grams/mol Mol/liter etc. To put it shortly the conversion factor denominator is always paired with the numerator.
How do you know which unit of conversion factor must be in the denominator?
The unit that is used in the denominator is the one to cancels the unit that appears in a numerator.
