Answer:
weakness, There are two conditions that lead to a weak volcanic eruption, low viscosity magma and little presence of trapped gases.
strength, The VEI or (Volcanic Explosivity Index) is a scale that describes the size of explosive volcanic eruptions based on magnitude and intensity. The numerical scale (from 0 to 8) is a logarithmic scale, and is generally analogous to the Richter and other magnitude scales for the size of earthquakes.
Explanation:
i really hope this helps. :)
M(O)= 16 g/mol
M(H)=1 g/mol
m(O)/m(substance)
1) 16/17
2)16/18
3) 16/19
4) 32/34=16/17
1) and 4) give the same answers, and 16/17 are the greatest fraction, so greatest % oxygen by mass also.
The answers should be 1) and 4).
