Answer: Ag, Zn, Pd. (Ag is has the highest conductivity and Pd has the lowest conductivity).
Explanation:
The correct answer is not among the options given.
You must look up the electrical conductivity of these metals in a table of metal properties.
The values that you can find are:
- Ag: 62.1 × 10⁶ Siemmens / m
- Zn: 16.6 × 10⁶ Siemmens / m
- Pd: 9.5 × 10⁶ Siemmens / m
So in order of decreasing conductivity the list is Ag > Zn > Pd.
Signs that a chemical reaction is occurring are: 1. change in color 2. change in odor 3. change in pH, as in changes from acid to base or base to acid
Answer: mass of SO2 is 160 g
Explanation: according to equation number of moles of SO2
Is same as amount of Oxygen, also 2.5 moles.
Molar mass of SO2 is 32.07 +2·16 = 64.07 g/mol
Mass is m= nM = 2.5 mol· 64.07 g/mol= 160.175 g
Answer:
D. Territory
Explanation:
Territory is defined as an area that is claimed by one or more individuals.
Territory is often used as a form of ownership of land or water mass between two parties. It is important as it gives each party a knowledge of their designated areas.
This validates it being an area that is claimed by one or more parties as organisms use that to protect their interest of food, water and mates for their survival.
If an least one neutron from U-235 fission<span> strikes another nucleus and causes it to fission, then the chain reaction will continue. If the reaction will sustain itself, it is said to be "critical", and the mass of U-235 required to produced the critical condition is said to be a "</span>critical mass<span>". A critical chain reaction can be achieved at low concentrations of U-235 if the neutrons from fission are </span>moderated to lower their speed, since the probability for fission with slow neutrons is greater. <span>A fission chain reaction produces intermediate mass </span>fragments<span> which are highly </span>radioactive<span> and produce further energy by their radioactive decay. Some of them produce neutrons, called </span>delayed neutrons<span>, which contribute to the fission chain reaction.
