Answer:
corrosion of aluminum metal by hydrochloric acid - chemical change
melting wax - physical change
pulverizing an aspirin tablet - physical change
digesting a Three Musketeersbar - chemical change
explosion of nitroglycerin - chemical change
a burning match - chemical change
metal warming up, due to the burning match - physical change
water vapor condensing on the metal - physical change
the metal oxidizes, becoming dull and brittle - chemical change
salt being dissolved by water - physical change
Explanation:
A chemical change is one in which a new substance is produced and it is not easily reversible. A chemical change always goes with absorption or evolution of heat.
On the other hand, a physical change is one in which no new substance is formed and it is easily reversible.
The processes mentioned in the question were classified into physical and chemical changes as we can see in the answer section.

Nearby streams are overflowing when it rains in a newly developed area. What would reduce runoff the most in the area? A. Add storm drains to one of the parking lots B. Build a park with many trees C. Build an apartment complex D. Encourage people to drive to work
Answer:
I think the answer is c
Explanation:
when the weather is be rainy the clouds closed the sky and it marks the weather can be rain so this means much water may attack the some builds such as park or cinema or theater and lot of people may dead in this case
When the weather is wet, the clouds cover the sky, signalling that rain may fall. Which implies that a lot of water may assault certain structures, such as parks, theatres, and cinemas, and many people may perish as a result. Thus, option C is correct.
What reduce run off the most in the area?Creating wetlands or vegetated buffer strips between cultivated land and waterways to filter pollutants out of run off and slow it down; and. Agriculture run off can be directed to wetlands, infiltration ponds, and retention ponds to decrease run off and improve water quality.
By collecting and storing rainwater in the canopy and releasing it into the sky through evapotranspiration, trees, and forests limit stormwater run off. In addition, soil conditions facilitated by tree roots and leaf litter enhance rainwater infiltration.
Therefore, Rainfall harvesting, engineered infiltration, evaporation, transpiration, canopy interception, and prolonged filtration are some methods for reducing run-off.

What are the differences between architects and engineers? in box
Answer:
Both are professional titles acquired through specific schooling and a licensing process.
With regards to the building industry, an architect is the generalist and an engineer is the specialist. Generally, the architect is the conceptual designer of the project, involved through all stages of a project. Engineers come and go (some stay significantly longer than others) and focus on a specific aspect of a building such as the mechanical systems or the structure. Architects and engineers together make up "the design team," and they work together to make the design complete. Architectural elements may be moved for the structure to make more sense and vice versa. The architect is usually the overseer, communicating with all the disciplines involved. The architect is likely the first to notice that the proposed ductwork conflicts with a structural beam, for example.
If the project is large enough, you might have two sets of architect teams: the design architect and the executive architect, also known as the Architect of Record. The executive architect has a more technical focus.
The technical aspects of architecture include compliance with building codes and figuring out all the building stuff related to the final product. For example, a plumbing engineer's drawing will have a line on a drawing representing a plumbing line. An architect's drawing might include a detail that shows that plumbing line as an actual pipe with a thickness with the bricks and cement block of the wall it is penetrating as well as whatever seal will be keeping the rain out.
Because of the difference in role and scope between an architect and engineer, the engineer of a project will be working on many other projects simultaneously, while the architect is dedicated to a few or just the one.

When your tire blows out in the middle of a drive, you should A. let go of the steering wheel B. pump the brakes immediately C. grip the steering wheel firmly D. immediately steer to the side of the road
Answer:
c) grip the steering wheel firmly
Explanation:
A) does not make sense because if you let the steering wheel go, you will loose complete control over the vehicle. DON'T DO THIS!
B) Pumping the brakes immediately is NOT recommended in this situation. Articles show that you should if anything accelerate slightly (if needed) to keep the car's momentum until you have gained enough control of the vehicle to where you are able to pull off to the shoulder.
D) Allow yourself the time to get the car under control before immediately pulling off to the shoulder. Depending on which side the tire blew, the car will naturally steer that direction. Pull the steering wheel the opposite direction the car's tire is pulling.
