An electron shifts from a lower energy to a higher energy
Answer:
The answer to your question is 21.45 g of KBr
Explanation:
Chemical reaction
2K + Br₂ ⇒ 2KBr
14.4 ?
Process
1.- Calculate the molecular mass of bromine and potassium bromide
Bromine = 2 x 79.9 = 159.8g
Potassium bromide = 2(79.9 + 39.1) = 238 g
2.- Solve it using proportions
159.8 g of Bromine ------------ 238 g of potassium bromide
14.4 g of Bromine ------------ x
x = (14.4 x 238) / 159.8
x = 3427.2 / 159.8
x = 21.45g of KBr
True
sound travels as energy, unlike light.. the waves transmit energy by changing the motion of particles. The particles are moving in the same direction as the wave.
What is the answer to this question
Answer:
You must equalize the pressure inside and outside the flask to determine the total because it keeps the water level the same.
