The kind of magma that is found in the most explosive volcanoes, the composite volcanoes, is andesitic magma. It is magma that is quite high in silica content which makes it thick, sticky and gooey. Great lumps of this sticky magma cool at the top of the volcano to form a sealed cap. Magma beneath the cap builds up and pressure mounts and eventually becomes too much to be contained and the magma violently erupts out from the top, blowing out the cap and shooting miles up into the air and in all directions.
The kind of magma found in gentle volcanoes such as shield volcanoes is runny in consistency. It has very minimal amounts of silica and is not thick but loose. It therefore tends to trickle out of the top of the volcano rather than erupt or explode.
Answer:
5
Explanation:
According to the Law of Conservation of Matter, the mass of the products in a chemical reaction must equal the mass of the reactants.
5O2 = 10 Oxygen atoms
In 2POx there must be 10 Oxygen atoms too. => x = 5
...
Hope it can help you.
Answer:
SiCl4 + H2O = SiO2 + HCl
Reactant. product
Si = 1 atom Si = 1 atom
Cl = 4 atom Cl = 1 atom
H = 2 atom H = 1 atom
O = 1 atom O = 2 atom
SiCl4. + 2H2o = SiO2 + 4hcl
Reactant. product
Si = 1 atom Si = 1 atom
Cl = 4 atom Cl = 4 atom
H = 4 atom H = 4 atom
O = 2 atom O = 2 atom
Balanced chemical equation.
Answer:
True
Explanation:
Both work because an element would be pure and compounds can be split into elements. This will work unless the substance isnt chemcially pure, but in this case it is so the answer would be true.
5600 why because you take away and then you add then yeah
