It's usually water and a type of salt take the reaction between hydrochloric acid and sodium hydroxide HCl(aq)+NaOH(aq) yeilds NaCl(aq) and H2O(l)
Answer:
D. has different properties when sampled in different areas.
Explanation:
The general property of a mixture says that each substance or component in a mixture has its individual or different property which can be separated on the basis of different methods.
Such as a mixture of oil and water is a heterogeneous mixture and have different properties or different densities, which helps them to be sampled in different areas.
Hence, the correct answer is "D".
Hey You!
The Correct Answer Is: True.
I Really Hope This Helped You, Good Luck With Your Studies! =)
Answer:
Low energy waves have <u>a long wavelength.</u>
Explanation:
Energy of wave is directly related to the frequency while it is inversely proportional to the wavelength.
If any wave have high energy it will have high frequency and smaller wavelength.
If the wave have lower energy then it will have lower frequency and higher wavelength.
Mathematical relationship:
E = h. f
E = h. c/λ
E= energy
h = planck's constant
f = frequency
c = speed of light
λ = wavelength
To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.
