Most of the light passes through glass but none of the light passes through metal.
CO₂, will have the lowest boiling point among the following ,therefore option (d) is correct.
<h3>What do you mean by the boiling point?</h3>
The temperature at which liquid vapor pressure equals atmospheric pressure is referred to as boiling point.
The boiling point is defined as the temperature at which a liquid’s saturated vapor pressure equals the atmospheric pressure surrounding it.
The boiling point for any material is the temperature point at which the material transforms into its form.
The one with the lowest boiling point has the weakest intermolecular forces.
CO₂, will have the lowest boiling point among the following ,therefore option (d) is correct.

Answer:
496 g
Explanation:
Let's consider the reaction between ethanol and oxygen to form acetic acid and water.
CH₃CH₂OH + O₂ → CH₃COOH + H₂O
The molar ratio of CH₃CH₂OH to CH₃COOH is 1:1. The moles of acetic acid produced by the reaction of 8.26 moles of ethanol are:
8.26 mol CH₃CH₂OH × (1 mol CH₃COOH/1 mol CH₃CH₂OH) = 8.26 mol CH₃COOH
The molar mass of acetic acid is 60.05 g/mol. The mass corresponding to 8.26 moles is:
8.26 mol × 60.05 g/mol = 496 g
It is either concave lens or mirror but since this is reflecting out rather than reflecting back it has to be concave lens. hope that helps! :’)
The amount of heat required is calculated using the below formula
Q(heat) =M(mass) xC(specific heat capacity)x delta T (change in temperature)
change in the temperature in kelvin=(35+273)- (25 +2730= 10K
c= 2.48 j/g/k
mass= 54.0 g
Q= 54.0 g x 2.48 j/g/k x 10k = 1339.2 joules is required
