Answer:
Convergent boundaries form when two crustal plates are colliding. ... The subducting plate is being recycled as it begins to melt at about 100 kilometers. The water soaked oceanic plate forms molten rock that collects in magma ... If the break is along hundreds of kilometers of fault line a megathrust earthquake occurs.
Explanation:
The balanced chemical reaction is:
FePO4<span> + </span>Na2SO4<span> = Fe2(SO4)3 + Na3PO4</span><span>
We are given the amount of </span><span>FePO4 is given to be used in this reaction. This will be the starting point for the calculations.
20.0 g </span>FePO4 ( 1 mol FePO4/ 150.82 g FePO4 ) ( 1 mol Fe2(SO4)3 / 1 mol FePO4) ( 399.88 g Fe2(SO4)3/ 1 mol Fe2(SO4)3) = 53.0274 g <span>Fe2(SO4)3</span>
<h2>Hey there!</h2>
<h3>Basic solution contain no OH - ions, is the correct option.</h3>
<h2>Explanation:</h2>
<h3>The solution which produce H+ ions is known as Acidic solution. </h3>
<h3>The solution which produce OH- ions is known as Basic solution. </h3>
<h3>So,here option number "C" is correct statement, rest all options are incorrect. </h3>

Answer:
3Mg + Fe₂O₃ → 2 Fe + 3MgO
Explanation:
Chemical equation;
Mg + Fe₂O₃ → Fe + MgO
Balanced Chemical equation;
3Mg + Fe₂O₃ → 2Fe + 3MgO
This is the balanced equation. There are three magnesium, two iron and three oxygen atoms are on both side of equation thus it follow the law of conservation of mass.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
