Chromatography is a laboratory technique used to separate a mixture. THe scientist could induce the use of chromatography to draw out the different components of the orange juice. From there, he could analyze and conduct further experiments to determine whether of not an illegal additive is being used in the orange juice.
Nitrate has 3 electron domains and no lone pairs. So NO3– molecular geometry is slightly bent and is trigonal planar. The bond angle is 120o.
Answer:
B) Ammonia gas
Explanation:
Ammonia gas: It consists of only one molecule namely ammonia throughout the substance so it is a pure single substance.
Answer:
1.736 × 10⁶
Explanation:
Data provided in the question:
Intensity of the energy received from the sun = 1.1 kW/m² = 1.1 × 10³ W/m²
Energy required to arrive = 1.91 × 10⁹ J
Area at the surface = 1 m²
Now,
we know that
Energy = Intensity × Area × Time
or
1.91 × 10⁹ = ( 1.1 × 10³ ) × 1 × Time
or
Time = [ 1.91 × 10⁹ ] ÷ [ 1.1 × 10³ ]
or
Time = 1.736 × 10⁶
