Answer:
D. number of neutrons
Explanation:
Isotopes of the same element must have the same number of neutrons. Neutrons of an atom are the uncharged particles within the nucleus.
Isotopy is the existence of two or more atoms of the same element having the same atomic number but having different mass number due to the differences in the number of neutrons in their various nuclei.
Therefore, isotopes differs based on the number of neutrons they contain.
Answer:
c = .137 J/g
Explanation:
q = mcΔT, where q=heat, m=mass, c=specific heat, ΔT=change in temp.
q = 96 J
m = 35 g
c = ?
ΔT = Tfinal - Tinitial = 313 - 293 K = 20 K
q = mcΔT
96 = 35c*20
96 = 700c
<u>c = .137 J/g</u>
- less than 50 centimeters of rainfall per year
- coarse-textured soils
- temperatures that change drastically between the day and night time
- high evaporation rates
- drought resistant vegetation
Answer: 22.4L
Gas at STP means gas at standard temperature and pressure of one mole of an ideal gas
Ideal gas Law PV=nRT
Standard pressure is 1atm or 22.4L
Standard temperature is 273.15K
