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 <u>regulatory policy </u>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 <u>regulatory policy </u>change.

True, because diatomic elements (H2, O2, F2, Br2, I2, N2, Cl2) consist of only one element but are molecules with covalent bonds.
Answer:
Intermolecular forces: forces attracting one molecule to its neighbors.
Explanation:
Hello,
Bonds are formed when two molecules are interacting (crashing or attracting to each other) and they are allowed to get joined via their valence electrons since we're talking about bonds. Those forces are called intermolecular forces as long as the molecules have charges that could attract or repeal another molecule (neighbors), of course, as we're considering bonds, we talk about attractive forces, making the bonding to be effective.

They appear on both sides of the reaction, hence did not take part in the reaction.
Ans:
from the product / reactant solution
from the environment when no solution is involved
Endothermic reactions are those reactions that proceed with the absorption of heat energy. In this case, the enthalpy of the reactants i.e. the initial energy is lower than that of the products. Therefore, energy needs to be supplied in order to break the bonds in the reactants and allow the reaction to proceed. This energy can be absorbed either from the environment when no solution is involved or from the product reactant solution.
For example, electrolysis of water which produces H2 and O2 is an endothermic reaction. Here, energy is absorbed by water in the form of electricity (current) to split it into corresponding products.
