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.
Answer:
15 mL of 15% acid solution and 30 mL of 3% acid solution
Explanation:
The total number of moles of the mixture is equivalent to the addition of the number of moles of the first solution and the number of moles of the second solution . Mathematically,
The volume of the mixture = 45 mL
The volume of first solution = x
The volume of second solution = 45 - x
Therefore:
0.15x + 0.03(45-x) = 0.07*45
0.15x + 1.35-0.03x = 3.15
0.12x = 1.8
x = 15
Thus, the volume of the first solution is 15 mL while the volume of the second solution is 30 mL.
It gains or loses electrons to become like the Noble gases having 8 valence electrons to become the most stable.
Answer:
The total pressure of the mixture is 1.657 atm
Explanation:
Step 1: Data given
Mol fraction of H2 = 0.35
Pressure of H2 = 0.58 atm
Partial pressure gas = total pressure gas * mol fraction gas
Step 2: Calculate the total pressure
Partial pressure H2 = total pressure * mol fraction
0.58 atm = total pressure * 0.35
Total pressure = 0.58 atm / 0.35
Total pressure = 1.657 atm
The total pressure of the mixture is 1.657 atm
•Have high melting and boiling points.
Dissolve in water.
•Conduct electricity either dissolved in water or in molten state.
•Form 3D network called lattice.
NOTE:Giant covalent structures also form lattice. E.g graphite and diamond which are allotropes of the element carbon.
