Answer:
Na
Explanation:
When identifying elements, you only need to look at the number of protons. Elements can have varying numbers of electrons and neutrons, but they can only have one number of protons.
Looking at the periodic table, the elements with 11 protons is sodium (Na).
Answer:
An intensive property is a property of matter that does not change as the amount of matter changes. It is a bulk property, which means it is a physical property that is not dependent on the size or mass of a sample.
In contrast, an extensive property is one that does depend on sample size. Examples of extensive properties include mass and volume.
Answer:
A, B and D
Explanation:
The rate determining step decides the overall rate of reaction and the species involved in the rate determining step determine the overall order of reaction. All the elementary steps in the mechanism sum up to give the overall reaction equation. However, transient intermediates only appear in elementary reaction equations and not the overall reaction equation.
Answer: Option (c) is the correct answer.
Explanation:
Temperature is used as for measuring the average kinetic energy present in a substance or object.
The internal kinetic energy obtained by the molecules of an object is known as thermal energy.
Hence, temperature measures the thermal energy of an object.
Whereas when this thermal energy flows from a hotter object to a cooler object which are placed adjacent to each other then it is known that heat is flowing.
Thus, we can conclude that heat differ from temperature as temperature measures thermal energy, and heat is the flow of thermal energy.
