Answer:
Explanation:The main difference between ionic covalent and metallic bonds is their formation; ionic bonds form when one atom provides electrons to another atom whereas covalent bonds form when two atom shares their valence electrons and metallic bonds form when a variable number of atoms share a variable number of electrons in a metal lattice.
Answer:
Mt. Pinatubo is one of the contrasting volcanoes that erupted violently in the year 1991, being the second strongest volcanic eruption that took place on earth in this entire century.
The 3 hypothesis that was proposed in order to describe the seismic activity of Pinatubo includes-
- The magma rising upward to the surface from the interior of the earth, erupting through the crater of the volcano.
- The eruption led to the releasing of a large number of volcanic gases into the atmosphere.
- The earthquakes are produced due to the continuous tectonic activities that are primarily caused when the earth's crust moves over the layer of viscous asthenosphere.
A large number of volcanic gases are released such as sulfur dioxide (SO₂), methane (CH₄), Hydrogen sulfide (H₂O), Carbon monoxide (CO), and other gases, due to the formation of convection currents and rising up of magma from the mantle, creating volcanic eruptions at the surface

Answer:
(NH4)2CO3(s) → 2 NH3(g) + CO2(g) + H2O(g)
Explanation:
The balanced equation can be written when we know the chemical formula of each reactants and products of the reaction.
Ammonium carbonate = (NH4)2CO3(s)
Ammonia = NH3(g)
carbondioxide = CO2(g)
water = H2O(g)
The ammonium carbonate was decomposed in the reaction , so ,
(NH4)2CO3(s) → NH3(g) + CO2(g) + H2O(g)
The reactant is on the left side while the product is on the right side. Let us balance the equation to make sure every atom of element is same number on both sides of the equation.
(NH4)2CO3(s) → 2 NH3(g) + CO2(g) + H2O(g)
