How can one determine the mole fraction of a substance in a mixture?
To determine the mole fraction of a substance in a mixture, you divide the moles of the substance by the total moles of all substances in the mixture. This gives you a ratio that represents the proportion of that substance in the mixture.
The amount of heat involved in the synthesis of 1 mole of a compound from its elements with all substances in their standard states at 25 and Acirc and degC is called?
The amount of heat involved in the synthesis of 1 mole of a compound from its elements, with all substances in their standard states at 25 °C, is called the standard enthalpy of formation (ΔH°f). This value is crucial in thermodynamics and helps in calculating the heat changes during chemical reactions. It is typically expressed in kilojoules per mole (kJ/mol).
What is a substance that has a uniform chemical composition throughout.?
The substances which are all having uniform chemical composition through out are all known as homogeneous substances.
Does the substances that take part in a chemical reaction keep their properties?
Some, but not all, substances do so. Such substances are known as catalysts.
