<h3>For the majority of the stars, a higher temperature tends to correlate with the higher luminosity. </h3>

<h3>Luminosity refers to the rate of the total radiant energy output of a star. It is the inherent brightness of a star covered over the whole electromagnetic spectrum. The luminosity of a star is a determination of its brightness. The more energy emitted, the higher the brightness. </h3><h3>Temperature also influences the rate of the luminosity of the star. As a star gets hotter or with the increase in temperature, the number of nuclear reactions upsurges, generation of more reactions and more energy takes place. Thus, ultimately resulting in higher luminosity of a star.</h3>

If 0.2 g of nitrobenzene are added to 10.9 g of naphthalene, calculate the molality of the solution. (given: molar mass of nitro
In-s [12.5K]

Molality is defined as 1 mole of a solute in 1 kg of solvent.  

Molality=

\frac{Number of moles of solute}{Mass of solvent in kg}

Number of moles of solute, n=  

\frac{Given mass of the substance}{Molar mass of the substance}

Given mass of the nitrobenzene=0.2 g

Molar mass of the substance= 123.06 g mol⁻¹

Number of moles of nitrobenzene,  

n= \frac{0.2 }{123.06}

Number of moles of nitrobenzene, n= 0.0016  mol

Mass of 10.9 g of naphthalene in kg=0.0109  

Molality= \frac{0.0016}{0.0109 }

Molality= 0.146 m

Fynjy0 [20]

Answer:

Neither arre correct

Explanation:

Neither Anya nor Braden are correct. This is because if you use 90 degrees, 180 degrees, or even 270 degrees you will not get the exact image, which means that the image will not be found by just a rotation because there will be a curve in the image. You can solve it if you can do 90 degree rotation and translation.

Answer:

CO₂

Explanation:

The product of the reaction is CO₂.

In a chemical reaction, the product is the substance usually found on the right hand side of the expression.

  Reaction equation is given as;

          C  +  O₂  →  CO₂  

In this reaction, C and O₂ are the reactants
