NH4 itself is called ammonium ion with positive charge of 1+. hence the oxidation state will be +1
OH itself is called hydroxide ion with negative charge of 1-. hence the oxidation state will be -1
there's actually no such compound as stated in your chemical formula. although it's simply called ammonium hydroxide by looking at the chemical formula, in fact the compound should rightly be called as aqueous ammonia with chemical formula of NH3 (aq). this is because the ammonia molecule will ionise due to the presence of water molecule to be protonated, hence forming ammonium ion and hydroxide ion in the solution.
A because a primary source is defined as a first hand account of an event .
Answer:
When magma reaches the surface, its dissolved gas content increases is true
<u>Explanation</u>:
The volcanic eruptions happen because of magma that is expelled on the earth’s surface. At the earth’s depth, all magma have gas dissolved in liquid. When the pressure has decreased the magma rises towards the earth’s surface creating a separate vapour phase.
As pressure reduces the volume of gas will expands and giving magma its 'explosive character'. Thus, as magma reaches the surface the dissolved gas content decreases and magma comes out of earth’s surface.
Changes in energy and formation of new substances.
