Explanation:
physical changes : boiling water, freezing water, a pencil being sharpened.
chemical change : rotting cheese, exploding dynamite.
Answer:
boiling water
a pencil being sharpened
freezing water
Explanation:
A change that does not lead to any difference in chemical composition of a substance is known as a physical change.
For example, shape, size, mass, volume, density, boiling point, etc of a substance are all physical properties.
On the other hand, changes that lead to bring change in chemical composition of a substance is known as a chemical change.
For example, exploding dynamite, rotting cheese etc are all chemical changes.
Chemical change is the change in which there is rearrangement of atoms and the new substances get formed.
Boiling water only changes the phase from liquid to gas and thus is a physical change.
Pencil on being sharpened only gets smaller in size and thus is a physical change.
exploding dynamite would result into formation of new substances and hence a chemical change.
Freezing water only changes the phase from liquid to solid and thus is a physical change.
Rotting cheese would result in formation of new substances and hence a chemical change.
Therefore, we can conclude that following are the physical changes in matter.
boiling water.
a pencil being sharpened.
freezing water.

when the orbitals or energy levels of an atom are full, it is considered to be stable. which atom in the ground state has a stable electron configuration?
Answer:
Noble gases, atoms which have complete filled outer orbits.
Explanation:
SInce, you have given no options elements like Neon, Helium,etc
Noble elements are the atoms which have stable electronic configuration in the ground state.
What is electronic configuration?
Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

bp’s efforts to close the blowout preventer and install a containment dome following an explosion on the deepwater horizon drilling rig is an example of ________ change.
The British Petroleum (bp's) effort to close the blowout preventer and install a containment dome following an explosion on the deepwater horizon drilling rig is an example of regulatory policy change.
The deepwater horizon drilling rig is a semi-submersible, transportable, floating, flexibly oriented drilling rig that could work in sea depths of up to 10,000 feet which is approximately 3,000 meters.
During the explosion that occurred in April 2010, British Petroleum made several efforts to contain the damages made and to prevent further outbreaks of disasters.
Part of the changes was shifting from a blowout preventer that has a specialized valve to seal, manage, and monitor oil and gas wells in order to prevent blowouts to a containment dome (a crucial component of a system meant to control an oil well's underwater blowout).
Therefore, we can conclude that the British Petroleum (bp's) effort to close the blowout preventer and install a containment dome following an explosion on the deepwater horizon drilling rig is an example of regulatory policy change.

Answer:
A homologous series is a series of compounds with the same general formula, usually varying by a single parameter such as the length of a carbon chain. Compounds within a homologous series typically have a fixed set of functional groups that gives them similar chemical and physical properties.
A student makes two mixtures, both made of the same substances. What must be true of the two mixtures? A Both mixtures have the same density. B Both mixtures have the same temperature. C Both mixtures can be physically separated into its components. D Both mixtures are physically combined in the same proportions.
A student makes two mixtures, both made of the same substances. Both mixtures can be physically separated into its components. Therefore, option C is correct.
What is mixture ?A substance made up of two or more separate chemical compounds that are not chemically linked is referred to as a mixture. A mixture is the physical blending of two or more substances while maintaining their distinct identities. It can take the form of solutions or suspensions.
A pure substance is a single sort of matter that cannot be divided into other kinds of matter by any physical methods. A pure substance has a known and consistent composition at all times.
When two or more distinct substances physically join, a mixture is produced that can be dispersed back into its constituent parts. When two or more compounds combine to create a new substance that cannot be broken down into its constituent parts, a chemical reaction takes place.
Thus, option C is correct.

Describe what does happen to the electrons when metal atoms are bonded together.
Answer: In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions. Metals are shiny.
