Answer
Rotating
Explanation:
The Earth is always being pulled towards the Sun by gravity.
The Earth is not moving fast enough to "escape" the Sun's gravity and leave the solar system, but it is going too fast to be pulled into the Sun. Therefore, it keeps going around and around( roating)- orbiting the Sun.
Answer:
Option A, The pH of the solution is 2.7 and the solution is acidic
Explanation:
As we know,
pH = - log [H3O+]
Substituting the given values, we get
pH = - log [2.1 x 10-3 M]
pH = - (-2.678)
pH = 2.678 or 2.7
The solution is acidic as pH value is less than 7
Hence, option A is correct
Answer:
In a climatological sense, dryness is a function of both annual rainfall and evaporation
It well be 9025 because it will dissolve in 0.8 hcl soluiton
