13) A bomb calorimeter for the determination of of combustions of organic compound was standardized by turning 0.25g methane that the observed tenperature rise was 3.5k. If the of combustion of methane is-815kj/ mol. calculate the heat capacity of the calorimeter and its content (C= ( 2H-1; 0= 16 molar heat​

What is the number of moles in 15.0 g ash3?

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.

Which statement is true about this reaction? 14n+1h 15o it is a practical source of energy on earth. it occurs only outside the solar system. its product is heavier than each of its reactants. it shows the critical mass of an element.
