Answer:
Explanation:
NH₄NO₃ = NH₄⁺ +NO₃⁻
heat released by water = msΔ T
m is mass , s is specific heat and ΔT is fall in temperature
= 50 x 4.18 x ( 22 - 16.5 ) ( mass of 50 mL is 50 g )
= 1149.5 J .
This heat will be absorbed by the reaction above .
q for the reaction = + 1149.5 J
2 )
molecular weight of NH₄NO₃ = 80
No of moles reacted = 5/80 = 1 / 16 moles.
3 )
5 g absorbs 1149.5 J
80 g absorbs 1149.5 x 16 J
= 18392 J
= 18.392 kJ.
= + 18.392 kJ
ΔH = 18.392 kJ / mol
Answer:
A neutron is a subatomic particle with a mass comparable to a proton and a neutral electrical charge. A neutron is a subatomic particle with a mass of 1 and charge of 0. ... While the number of protons in a atom determines its element, the number of neutrons determines its isotope
Explanation:
thank me later:()
B- Carbon dioxide, every other option listed is composed of more than one thing.
Answer:
Explanation:
half life = 1600 years .
m = M x 
m is mass of the radioactive object after n half lives , M is original mass.
n = 4800 / 1600
= 4
Putting the valus of n and M we have
m = .25 x 
= .03125 g .
gene therapy
Explanation:
Gene therapy, also called gene transfer therapy, the introduction of a normal gene into an individual's order to repair a mutation that causes a genetic disease.
