Answer:
No of Moles in excess at the end of the reaction is 0.25 moles
Explanation:
AgNO3 + Mg3P2 → Ag3P + Mg(NO3)2
Balancing the equation we get
6AgNO3 + Mg3P2 → 2Ag3P + 3Mg(NO3)2
6 moles of AgNO3 needs 1 mole of Mg3P2
using unitary method
AgNO3 = 
1.5 AgNO3 = 
= 1/4 = 0.25moles of Mg3P2
So 1.5 Moles of AgNO3 requires 0.25Mg3P2 for complete reaction but we have 0.5Moles of Mg3P2 available Therefore Mg3P2 is in excess
No of Moles in excess at the end of the reaction = 0.5 - 0.25 = 0.25moles
Answer:
kinetic energy remains unchanged
Answer:
25 mL
Explanation:
Step 1: Given data
- Concentration of the concentrated solution (C₁): 2 M
- Volume of the concentrated solution (V₁): ?
- Concentration of the diluted solution (C₂): 0.1 M
- Volume of the diluted solution (V₂): 0.500 L
Step 2: Calculate the volume of the concentrated NaCl solution
We will use the dilution rule.
C₁ × V₁ = C₂ × V₂
V₁ = C₂ × V₂ / C₁
V₁ = 0.1 M × 0.500 L / 2 M
V₁ = 0.025 L = 25 mL
Answer: As the temperature of a molecular system increases, the kinetic energy of molecules also increase. Also as the temperature of a molecular system decreases, the kinetic energy of the molecules will also decrease.
Explanation:
James Clerk Maxwell developed the kinetic-molecular theory (KMT) of gases. In this theoey, five assumptions concerning an ideal gas was made. One of the them was that," the average kinetic energy of the gas molecules is proportional to the temperature of the gas". This simply means that a s the temperature of a molecular system increases, the kinetic energy of molecules also increase. Also as the temperature of a molecular system decreases, the kinetic energy of the molecules will also decrease.
Also another scientist known as Rudolf Clausius incorporated energy into the kinetic theory. He proposed that heat is a form of energy that affects the temperature of matter by changing the motion of molecules in matter.
Heat is defined as the flow of energy which is caused by difference in temperature.
In conclusion, when the temperature of a system is increased, the collision of the molecules with one another and the walls of their container increases as more molecules gain more heat energy at higher temperature. While as the temperature of the system decreases, the collision of the molecules will also decrease as molecules lose heat energy at lower temperature.
The equation used for the calculation is P subscript 1 V subscript 1 equals P subscript 2 V subscript 2. Thus, option B is correct.
The pressure of the gas with respect to volume is given with inverse proportion. The ideal gas equation is given as:
<h3>Equation for relation between volume and pressure</h3>
The initial pressure of the gas has been given as, 
The initial volume of the gas has been, 
The final volume of the gas has been, 
The final pressure of the gas, 
is given as:
Thus, the equation used for the calculation is P subscript 1 V subscript 1 equals P subscript 2 V subscript 2. Thus, option B is correct.
