Answer:
Visible light spectrum is a part of electromagnetic waves. The colors of the visible light spectrum are organised on the basis of their wavelength and frequency.
As the light or color having high frequency will have the shorter wavelength and vice versa, so colors in visible light spectrum arranged from highest frequency to lowest frequency or from shortest wavelength to highest wavelength. For example: The highest frequency color is violet and lowest frequency of visible light is red.
The phylogeny of an organism is its evolutionary history.
Answer : The temperature of gas is, 295 K
Explanation :
To calculate the temperature of gas we are using ideal gas equation:
where,
P = Pressure of gas = 1.21 atm
V = Volume of gas = 10.0 L
n = number of moles = 0.500 mole
R = Gas constant = 
T = Temperature of gas = ?
Now put all the given values in above equation, we get:
Therefore, the temperature of gas is, 295 K
Answer:
the % yield is 82%
Explanation:
Given the data in the question,
we know that;
Molar mass of benzil is 210.23 g·mol−1
Molar mass of dibenzyl ketone is 210.27 g·mol−1
Molar mass of tetraphenylcyclopentadienone is 384.5 g·mol−1
Now,
2.0 g benzil = 2 g / 210.23 g·mol−1 = 0.0095 mole
2.2 g dibenzyl ketone = 2.2 / 210.27 = 0.0105 mole
3.0 g of tetraphenylcyclopentadienone = 3 / 384.5 = 0.0078 mole
Now, the limiting reagent is benzil. 0.0095 mole can reacts wiyh 0.0095 mole of dibenzyl ketone
percentage yield = ( 0.0078 mole / 0.0095 mole ) × 100%
= 0.82 × 100%
= 82%
Therefore, the % yield is 82%
The answer is C. Because you need the sun to start your cycle which starts with water evaporation
