the balanced chemical equation for the reaction is as follows
H₃PO₄ + 3KOH ---> K₃PO₄ + 3H₂O
stoichiometry of H₃PO₄ to KOH is 1:3
first we have to find which the limiiting reactant is
as the amount of product formed depends on the amount of limiting reactant present
number of H₃PO₄ moles reacted - 4.4 mol
if H₃PO₄ is the limiting reactant
1 mol of H₃PO₄ reacts with 3 mol of KOH
then 4.4 mol of H₃PO₄ reacts with - 3 x 4.4 mol = 13.2 mol of KOH
but only 3.8 mol of KOH is present
therefore KOH is the limiting reactant
stoichiometry of KOH to K₃PO₄ is 3:1
number of KOH moles reacted - 3.8 mol
therefore number of K₃PO₄ formed = number of KOH moles reacted / 3
= 3.8 mol / 3 = 1.3 mol
answer is 1.3 mol of K₃PO₄
Answer: Kinetic energy is energy that is associated with the constant movement of atoms or molecules. Kinetic energy is also called thermal energy, it is a form of motion. It is the motion of waves, electrons, atoms, molecules, substances, and objects!
Hope this helps a little bit
Answer:
State of matter is defined as a form in which matter can exist. There are four states of matter known till date. They are as follows:
Solid: Matter is said to be in solid state if it has definite shape and volume. The components of matter are closely packed and have fixed positions within the matter.
Liquid: In liquid state, matter has fixed volume but shape is not fixed, it takes the shape of container in which it is placed. The particles of liquid are close but can move freely or do not have fixed positions.
Gas: Matter in gaseous state has variable volume and shape. The particles of gas are very far from each other thus, they are in constant motion without any fixed position..
Plasma: This state of matter has variable shape and volume. It has neutral atoms, the number of ions and electrons are significant and can move freely in the matter. In order to make plasma, energy is required to strip electron from atom.
According to above definitions, the state of matter is matched with the given statements as follows:
Plasma-Particles are so hot that electrons are stripped from atoms.
Gas-It expands to fill the volume of the container.
Liquid-Particles move past each other freely but do not go fat apart.
Solid-It retains its shape regardless of the shape of the container.
Explanation:
I choose this because It understands how each plasma work.

<u>Convection currents are identified in Earth's mantle. Heated mantle material is shown rising from deep inside the mantle, while cooler mantle material sinks, creating a convection current. It is thought that this type of current is responsible for the movements of the plates of Earth's crust.</u>
