dehydration
electrolysis
distillation
The strongest acid will have a pH of _____.
0
1
13
14
Any atom which no longer has a neutral charge is called a(n) _______ .
atomic or ion
Answers
1. A pH scale measures how much acidic or basic a substance is. The pH scale usually ranges from 0 to 14. .... The pH scale would be, (0 - 14), I think. SO the second one for 1. :)
2. So, Since an automobile battery can explode or contain and cause a sulfuric acid burn. I'm thinking it would be thee 1st one for the 2nd! :) sulfuric acid
3. Electrochemical and electrolytic reduction cleaning processes, so.... they are the most common techniques utilized to halt, stabilize, and even reverse the oxidation of the metal. So Overall I think this would most-likely Be electrolysis.
4. Is 1, because, pH of 1 (e)
5.I am thinking this would Be ion. Because, an ion is an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
HOPE IT HELPS!!!! :)

The numbers in power of 10 notation would be :
3 trillion is expressed as 3 × 10¹².
Five-thousandths (0.005) are expressed as 5 × 10⁻³.
730,000,000,000,000 is expressed as 7.3 × 10¹⁴.
0.000000000082 is expressed as 8.2 × 10⁻¹¹.
3 trillion:
In standard form: 3,000,000,000,000
In powers of 10 notation: 3 × 10¹²
Explanation: In this number, 3 is multiplied by 10 raised to the power of 12, indicating that it is 3 followed by 12 zeros. This notation is particularly useful when dealing with very large numbers like the national debt or astronomical distances.
Five-thousandths (0.005):
In standard form: 0.005
In powers of 10 notation: 5 × 10⁻³
Explanation: Here, 5 is multiplied by 10 raised to the power of -3, indicating that it is 5 divided by 1,000 (10³). This notation helps represent fractions or very small quantities.
730,000,000,000,000:
In standard form: 730,000,000,000,000
In powers of 10 notation: 7.3 × 10¹⁴
Explanation: In this case, 7.3 is multiplied by 10 raised to the power of 14, indicating that it is 7.3 followed by 14 zeros. This notation simplifies the expression of extremely large numerical values.
0.000000000082:
In standard form: 0.000000000082
In powers of 10 notation: 8.2 × 10⁻¹¹
Explanation: Here, 8.2 is multiplied by 10 raised to the power of -11, indicating that it is 8.2 divided by 100 billion (10¹¹). This notation is useful when working with very small decimal fractions, such as in scientific measurements.
Powers of 10 notation with superscripts provides a clear and concise way to represent numbers across a wide range of scales, from the macroscopic to the microscopic, making it a fundamental concept in scientific notation.

Answer:
The required new pressure is 775 mm hg.
Explanation:
We are given that gas has a volume of 185 ml and a pressure of 310 mm hg. The desired volume is 74.0 ml.
We have to find the required new pressure.
Let the required new pressure be ''.
As we know that Boyle's law formula states that;
where, = original pressure of gas in the container = 310 mm hg
= required new pressure
= volume of gas in the container = 185 ml
= desired new volume of the gas = 74 ml
So,
= 775 mm hg
Hence, the required new pressure is 775 mm hg.

B. The equator is closer to the sun than the North pole
C. The equator receives more direct sunlight than the north pole.
D. The equator has more hours of daylight per year than the North Pole.
Answers
Answer:
C. The equator receives more direct sunlight than the north pole.
Explanation:
As we all know that earth is revolving around the sun. But the earth is also tilted at the angle of 23.5°, which means that the equator part of earth is facing sun directly while the north pole is tilted. As a result of this tilt, the north pole receives the rays of sun at certain angle which reduces the intensity and effect of sunlight. While the equator part, since it is facing the sun, receives sunlight at almost perpendicular. So, the absorption of heat by the earth's atmosphere and land is pretty much higher in equator as compared to north pole.

Final answer:
The force that pushes electrons along in a circuit is called the electric field.
Explanation:
The force that pushes electrons along in a circuit is called the electric field. The electric field in a wire points from the higher potential end to the lower potential end and provides the force necessary to keep the electrons moving. The electrons, carrying a negative charge, move on average in the opposite direction of the electric field.
