Answer:
D. Sr < Ca < Be
Step-by-step explanation:
<em>Ionization energ</em>y decreases from top to bottom within a Group, because the valence electrons are further from the nucleus and therefore easier to remove.
Thus, <em>Sr has the lowest</em> ionization energy and <em>Be the highes</em>t.
The correct order is Sr < Ca < Be.
Explanation:
There are two aspects of a reaction:
Thermodynamics:
Combustion of the compound is reaction with oxygen.
The carbohydrates contain more content of oxygen as compared to fats.
Hence, carbohydrates have lot of oxygen content which are already partially oxidized as compared to fats. Hence, combustion of the carbohydrates is a faster process.
Kinetics:
The molecular reacts also shows that the combustion of the carbohydrates is a faster process.
R is the mixture formed by adding 5 g of sugar to 1 L of water.
<h3>Which is a mixture?</h3>
A mixture is an impure substance made up of two or more substances which are miscible or immiscible in each other.
Dissolving the sugar in the water makes a homogenous mixture and once dissolved a solution is made by the combination of a solute (sugar) and solvent (water).
Hence, R is the mixture formed by adding 5 g of sugar to 1 L of water.
