Answer: or Sodium carbonate.
or Potassium permanganate
Explanation: ion carries 1 + charge whereas carbonate ion carries overall charge of -2. So for every carbonate ion, two sodium ions combine to balance the charges and thus form a stable compound,
Potassium ion carries 1 + charge where as permanganate ion carries overall charge of -1. So for every permanganate ion, one potassium ion combines to balance the charges and thus form a stable compound, Explanation:
Answer:
Because it is closer to earth than the other blue giant stars.
Explanation:
The sun is closer to earth than any other big star which means we see it bigger.

Answer:
Perfectly Specified
Explanation:
Given,
Pressure = P = 0.9 atm
and the Boiling point = T
Number of phases P = 1
Number of components C = 1
According to Gibb's phase rule ,
F = C - P + 2
If
- F = 0, the system is perfectly specified
- F > 0, the system is under specified
- F < 0 the system is over specified
At P = 0.9 atm, boiling point is T i.e. Fixed equal to 96.7 °C (from steam table)
P is independent variable and T is dependent variable (depends on the value of P ).
In this case only two variables are required to fix the system pressure and temperature.
In the given problem, pressure is fixed so the temperature is also fixed. There is no requirement of any other variable.
Therefore degree of freedom,
F = 0
The system is perfectly specified.
C. arteries, veins, capillaries
