Science does not have a way to control climate and weather conditions, particularly for the short term disturbances. What is possible is to establish sources of polluted water.
The other three, preventing excessive rain, the schedule of cyclones, and the frequency of severe weather conditions, are not under human control.
<span>Answer Choices:
A) Ca
B) O
C) Cl
D) s</span>
<span>the formula is Li2X, so the charge on the X anion must be 2-
the ion is X2- elements in group 6A form monatomic ions with a 2- charge. In your list that is O or Po
If the element can accomodate 12 electrons then it can have an expanded octet. Only elements in period 3 and higher can have expanded octets.
So you are looking for a group 6A element in period 3 or higher.
cA would not intereact with LI BECAUSE ITS A METAL The only element that fits the bill is D) S</span>
Answer:
E = 1.33 MeV = 2.13 x
J
v = wavelength = E / h = 2.13 x
/ 6.626 x
= 3.2 x
m
f = frequency = c / 3.2 x
m = 3 x
/ 3.2 x
= 9.375 x
Hz
Answer : The correct option is, They are different units of concentration.
Explanation :
Molarity : It is defined as the number of moles of solute present in one liter of solution.
Formula of molarity :

Mass percent : It is defined as the mass of solute present in the mass of solution.
Formula of mass percent :

Hence, both are the different unit of concentration.
