Answer:
Explanation:
Heat lost by metal = mass x specific heat x fall in temperature
= 74 x S x ( 94 - 32 )
= 4588 S
heat gained by water = mass x specific heat x rise in temperature
= 120 x 1 x ( 32 - 26.5 ) ( specific heat of water is 1 cals / gm )
= 660
Heat lost = heat gained
4588S = 660
S = .14 cal /gm .
Specific heat of metal = .14 cal / gm
Answer:
C+O2=CO2
Explanation:
no.of atoms on reactant side= no.of atoms on product side
The element itself is Yttrium, which is a transition metal and not that reactive. Since it has 39 protons it will also have 39 electrons.
a lung is NOT an organism.
