HELP ITS DUE TODAY put the number by which one you answer!!!!

Answers

Answer 1

1- Reactants (H = 2, O = 2)
Products (H = 2, O = 0)
2- Reactants (P = 4, O = 2)
Products (P = 2, O = 3)

So basically if it was H20, then there is 2 Hydrogen because the two is in front of the H and there isn’t a 2 in front of Oxygen.
However if it was H2O2, then there is two hydrogen and two oxygen because there is a two on both of the symbols which indicates how much reactants/products there is.

Hope this helps!

Steep slope with high mountain, as these are formed by a composite volcano
Gentle slope with mild hill, as these are formed by a composite volcano
Gentle slope with mild hill, as these are formed by a shield volcano
Steep slope with high mountain, as these are formed by a shield volcano

Answers

Answer:

Fluid lava (which is less viscous because it has less silica content) flows much further than viscous lava (that is high in silica content). Therefore, this types of lava forms shield volcanoes – low slopes and low height- because they flow over longer distances before they cool. Viscous lava from composite volcanoes that are high in height and have steep slopes.Explanation:
