A medium-temperature star like the Sun would most likely emit its most intense radiation as _____. A. Ultraviolet light B. Visible light C. Microwaves D. Radio waves
Answers
Answer:
The correct answer is option B, that is, visible light.
Explanation:
The Sun is a prime source of ultraviolet rays. Although the Sun discharges all of the distinct types of electromagnetic radiation, 99 percent of its rays are in the form of ultraviolet rays, visible light, and infrared rays. The Sun emits radiation all through the electromagnetic spectrum, that is, from extremely high-energy X-rays to ultra-lengthy wavelength radio waves, and everything that comes in between. However, the peak of the emission takes place in the visible part of the spectrum.

Electopositivity is the measure of the ability of elements to donate electrons to form positive ions. Whereas the Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. Group 1 is more electropositive than group 17 and group 17 is more electronegative than group 1.

c. weakly basic.
d. strongly basic.

A solution with a pH of 8.0 is weakly basic. Thus ,the correct option is C.
The pH scale gives the measure of the acidity or basicity of a solution. It ranges from 0 to 14, where a pH of 7 is considered neutral. Solutions which have a pH less than 7 are acidic, while solutions which have a pH greater than 7 are basic.
In this case, since the pH is 8.0, which is greater than 7, the solution is basic. However, it is important to note that the basicity of the solution is weak, as it is only slightly above neutral.
For example, think of a pH of 8.0 as being similar to water from a freshwater lake. It's not strongly basic like bleach or ammonia, but it still has a slightly basic nature compared to a neutral solution.
Thus, the correct option is C.

Explanation:
When give a number in scientific notation, the exponent tells you how many places to move the decimal point.
- Negative moves to the left.
- Positive moves to the right.
25) 1 cubic centimeter (cc) = 1 milliter (ml)
The conversion factor is 1 to 1. You just need to change cc to ml
