Label each as either physical or chemical change.
a.corrosion of aluminum metal by hydrochloric acid
b.melting wax
c.pulverizing an aspirin tablet
d. digesting a Three Musketeersbar
e. explosion of nitroglycerin
f. a burning match
g. metal warming up, due to the burning match
h. water vapor condensing on the metal
i.the metal oxidizes, becoming dull and brittle
j.salt being dissolved by water
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.

Solution 1 - Finding the X and Y intercepts
x-intercept: (0,0)
y-intercept: (0,0)
Solution 2 - Finding the Domain and Range
Domain: (- ∞ , ∞)
Range: (- ∞ , ∞)
Solution 3 - Finding the Slope and y-intercept
Slope: 9
y-intercept: (0,0)
Solution 4 - Solve for y
y = 9x
Solution 5 - Solve for x
x = [tex]\frac{y}{9}[/tex]

Hace 6 años compre un lote en $900.000, recibí un interés por la inversión $1.423.000, hallar la tasa de interés de este negocio
Answer:
Interest rate, R = 26.35%
Explanation:
Given the following data;
Time = 6 yearsPrincipal = $900,000Simple interest = $1,423,000To find the interest rate, we would use the following formula;
[tex] S.I = \frac {PRT}{100} [/tex]
Where;
S.I is the simple interest.P is the principal.R is the interest rate.T is the time measured in years.Making "R" the subject of formula, we have;
[tex] R = \frac {100S.I}{PT} [/tex]
Substituting the values into the formula, we have;
[tex] R = \frac {100 * 1423000}{900000 * 6} [/tex]
[tex] R = \frac {142300000}{5400000} [/tex]
Interest rate, R = 26.35%
Therefore, the interest rate of this business is 26.35 percent.

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.

Select two targets. Write two paragraphs, one for each target, identifying potential challenges that each target presents and describe possible methods to overcome those challenges. Use evidence from course content to support your responses.
Answer:
Explanation:
Target 1.1
By 2030, eradicate extreme poverty for all people everywhere is an extremely challenging target. First of all, there are almost 8 billions people on Earth. Each person in extreme poverty has different background and circumstances. It is difficult to come up with a plan that will help them all. The first step is international cooperation; involving rich countries giving ads to poorer countries.
Target 1.2
By 2030, reduce by half population living in poverty by national definitions is easier to accomplish than Target 1.1. The key here is "by national definitions." As different countries have different definitions for poverty, the standards are lower for poorer countries. Leaders in those countries will try to improve lives of their people so that they can be remembered as the ones who lift their countries out of poverty.

Triangular numbers can be represented with equilateral triangles formed by dots. The first five triangular numbers are 1, 3, 6, 10, and 15. Is there a direct variation between a triangular number and its position in the sequence? Explain your reasoning.
Answer:
No, the triangular numbers are not a direct variation. There is not a constant of variation between a number and its position in the sequence. The ratios of the numbers to their positions are not equal. Also, the points (1, 1), (2, 3), (3, 6), and so on, do not lie on a line.
Explanation:
this is correct on edge
