The molar mass of sodium is 22.99 ㅤ ㅤ ㅤ 22.99 (28) = 643.72 mol now multiply by avogrados number to find the number of atoms. ㅤ ㅤ ㅤ 643.72 (6.022 x 10^23) = 3.88 x 10^26 number of atoms
We can conclude that the solution is an <em>acid buffer</em>. A buffer system is when a weak acid is mixed with its salt. Its purpose is to resist changes in pH when small amounts of acid or base is added.

Answer:
H = 4,034,250 J
Explanation:
Mass, m = 165kg = 165,000g (Converting to grams)
Initial temperature = 15.7°C
Final temperature = 95.7°C
Temperature change, ΔT = 95.7 - 15.7 = 50°C
Specific heat capacity, c = 0.489 J/g·°C
Heat = ?
All the parameters are related with the equation below;
H = m * c * ΔT
H = 165000 * 0.489 * 50
H = 4,034,250 J
Explanation:
The electromagnetic spectrum shows the wavelength or frequency range of different waves starting from gamma rays to radio waves.
In the electromagnetic spectrum, gamma rays have shorter wavelength while radio wave have longest wavelength.
The correct order is as follows :
(A) Gamma rays
(B) X rays
(C) Ultraviolet
(D) Visible light
(E) Infrared waves
(F) Radio waves
So, the correct order form left to right in order of increasing wavelength is as follows :
Gamma rays < X rays < Ultraviolet < Visible Light < Infrared Waves < Radio Waves
