Answer:
<em>B. Female Merrick sea turtles begin returning to Bakerâs Beach to lay their eggs when they are ten years old.</em>
Explanation:
Firstly, There was an oil spill five years ago-no eggs hatched.
Now, the number of females coming back to the lay eggs has increased somewhat since the last five years.
The theory is that a period of 5 years is sufficient to assess effect on population.
If the breeding cycle has been found to be ten years long, then the impact of the oil spill on the population (as observed by the number of females returning to lay eggs) will only be perceived in the 10th year.
It undermines the argument that the oil spills don't impact the public.
Explanation:
Gold conducts heat and electricity. ...
Gold is ductile: It can be drawn out into the thinnest wire. ...
Gold is highly reflective of heat and light. ...
Gold is prized for its beauty. ...
Gold is malleable, so it can be flattened into extremely thin sheets.
on the other hand Gold consist of copper
Key Properties of Copper Alloys
Excellent heat conductivity.
Excellent electrical conductivity.
Good corrosion resistance.
Good biofouling resistance.
Good machinability.
Retention of mechanical and electrical properties at cryogenic temperatures.
Non-magnetic.
so the difference is that copper is less expensive and not priced with its beauty
Answer:
V = 42.6 L
Explanation:
Given data:
Number of moles of Cl₂ = 1.9 mol
Temperature and pressure = standard
Volume occupy = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
By putting values,
1 atm × V = 1.9 mol ×0.0821 atm.L /mol.K × 273.15 k
V = 42.6 atm.L / 1 atm
V = 42.6 L
NaOH but you didnt give options
The answer is A ( pure water has no free ions)
