Answer:
Both soluble metal salt and carbon dioxide may react with a base to form a solid or what we call a precipitate,
Answer:
Explanation:
Ammonium sulfate reacts with barium chloride to produce barium sulfate and ammonium chloride.
Answer:
Explanation:
The chemical formula for hydrogen is H while chemical formula for oxygen is O
Considering that two moles of hydrogen and 2 moles of oxygen react to form water, the equation will be
The number of oxygen molecules don't balance on both LHS and RHS hence to balance it, we put it as follows
Normally, two moles of hydrogen require only one mole of oxygen to form two moles of water.
Igneous rocks that cools very quickly when it forms may have a texture that is smooth and shiny with no visible grains.
Igneous rocks also called as magmatic rocks is one of the three main rock type present the other two being sedimentary and metamorphic rocks.These rocks are formed by cooling and solidification of magma or lava .
The magma is derived from from partial melts of rocks which are existing in the earth's crust or mantle.Melting is caused by one of the three processes increase in temperature, change in composition or decrease in pressure.
Igneous rocks are classified based according o their occurrence, texture, chemical composition or mineral content.According to their mode of occurrence they are classified as intrusive or extrusive igneous rocks.
