<u>Answer :</u>
Chemical energy - D) Potential energy stored in the bonds between atoms
Electrical energy - C) The movement of an electrical charge
Radiant energy - B) Electromagnetic energy that travels in waves
Thermal energy - A) Internal energy caused by vibrations of atoms and molecules
<u>Explanation :</u>
Chemical energy : It is the type of energy in which the potential energy is stored in the bonds between the atoms.
Electrical energy : It is a type of energy in which the electrical charge are moved.
Radiant energy : It is a type of energy in which the electromagnetic energy travels in the waves.
Thermal energy : It is a type of energy in which an internal energy caused by the vibrations of atoms and the molecules.
The balanced equation for the reaction is as follows;
Zn + 2HCl --> ZnCl₂ + H₂
stoichiometry of Zn to HCl is 1:2
limiting reagent is the reactant that is fully consumed in the reaction.
the amount of product formed depends on amount of limiting reactant present.
The excess reactant is when it has been provided in excess and only a fraction of the provided amount is used up in the reaction.
Amount of Zn moles - 0.5 mol
Amount of HCl moles - 0.6 mol
If Zn is provided, number of HCl moles reacted - 0.5 x 2 = 1.0 mol of HCl is required, but only 0.6 mol of HCl is provided.
HCl is therefore the limiting reactant,
Number of Zn moles required - 0.6 mol /2 = 0.3 mol
But 0.5 mol are given, therefore 0.2 mol of Zn is in excess
Answer:
I think its. SO2
Explanation:
the S is singular and there is 2 Os and thats what the model shows so I think I'm right
Answer:
C. 33.6L
Explanation:
Based on the reaction, 2 moles of HCl reacts producing 1 mole of hydrogen.
To solve this question we must find the moles of hydrogen produced using the reaction. Then, with combined gas law (PV = nRT) we can find the volume produced:
<em>Moles H2:</em>
3.00 moles HCl * (1mol H2 / 2mol HCl) = 1.50 moles H2 are produced
<em>Volume:</em>
PV = nRT
V = nRT / P
<em>Where P is pressure = 1atm at STP</em>
<em>V is volume = Our incognite</em>
<em>n are moles of the gas = 1.50 moles</em>
<em>R is gas constant = 0.082atmL/molK</em>
<em>T is absolute temperature = 273.15K</em>
<em />
V = nRT / P
V = 1.50mol*0.082atmL/molK*273.15K / 1atm
V = 33.6L
<h3>C. 33.6L</h3>
