Asample of propane (c3h8) has a mass of 0.47 g. the sample is burned in a bomb calorimeter that has a mass of 1.350 kg and a specific heat of 5.82 j/(g • °c). how much energy is released by the reaction if the temperature of the calorimeter rises by 2.87°c?

Heat gained or released by a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. It is expressed as follows:

Heat = mC(T2-T1)
Heat = 1350 (5.82) (2.87)
Heat = 22549 J or 22.55 kJ

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
