The balanced chemical equation for the reaction is as below
KBr (aq) + AgNo3 → KNO3(aq) + AgBr(s)
Explanation
from the equation above the stoichiometric coefficient before KBr is 1, before AgNo3 is 1 , before KNO3 is 1 and before AgBr is also 1. Therefore 1 mole of KBr reacted with 1 mole of AgNO3 to form 1 mole of KNO3 and 1 mole of AgBr.
H2SO4(aq)+NaOH(s)----->NA2SO4 + H20
I like people who are short and know what”a popppppppp
The color of the light depends on the element to which it interacts. On interacting with energy, the electrons goes to the higher excitation state and when electron drops to lower state which is more stable, the energy is re-emitted as light. Each element produces its own characteristic color.
In case of a sodium street lamp, more photons in the long wavelength are emitted by the sodium gas, leading to yellow color one see. Whereas in case of a neon light, the neon gas is a noble gas, stable and non-reactive. The electrons in neon will excite on applying current. The free electrons will collide with each other and then return back to the atoms. The energy is produced in the form of light on absorbing electrons by the atoms. This falls in the red region of spectrum and thus emits red color.
Answer:
P(B) = 0.45 atm
Explanation:
Given data:
Total pressure = 1.30 atm
Partial pressure of A = 0.85 atm
Pressure of B = ?
Solution:
Total pressure = P(A) + P(B)
P(B) = Total pressure - P(A)
P(B) = 1.30 atm - 0.85 atm
P(B) = 0.45 atm
